FOTD 31-12-02 (So Be It [6])
by Jim Muth 31 Dec '02

31 Dec '02

FOTD -- December 31, 2002 (Rating 6) Fractal visionaries and enthusiasts: With today's FOTD we end the year by returning to the MandelbrotMix4 formula and visiting the fractal created when 4.1 parts of Z^(-7.5) are added to 7.7 parts of Z^(-1.5). To make things even more interesting, we then add (1/C) rather than just straight C. The resulting fractal consists of a short string of bays with many spurious sub-bays and valleys. Today's scene lies in an unlikely part of a spiral in an unpromising area in the south- west corner of the parent fractal. I found it more by instinct than logic. In fact, I rarely use logic when searching for fractals -- it takes too much of the fun and surprise out of the search. I named the image "So Be It". The name has nothing to do with the appearance of the fractal. It expresses the mood that comes over me every year at this time, when another year passes irretrievably into the past. (which too many have already done) The image consists of a central midget surrounded by a ring of silk ribbons. Beyond the silky ring lies a dark mysterious area filled with somber purplish bows. The whole thing is a bit on the depressing side, and can be rated no higher than a 6. But a 6 is still above average, so the 14 minutes spent rendering the image from the parameter file will not be a total waste of time. And even the 14 minute wait can be avoided by visiting one of the FOTD web sites and downloading the finished image from there. Paul's FOTD web site can be accessed at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's can be found at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday brought a repeat of Sunday's weather to F.C., with sun, clouds, light breezes, and a temperature of 44F 6.5C, which was pleasant for humans but not pleasant enough for dynamic fractal cats. The duo's moods turned sulky as the afternoon progressed and the mud in the yard remained undried. As for myself, I expect a pleasant enough day. The non-fractal work is nearly finished, leaving me little to do for the rest of the day but keep my eye on the cats, search for fractals, and finish reading my latest issue of 'Skeptical Inquirer' magazine, a publication by skeptics for skeptics, whose purpose is to pro- mote reason and reassure the concerned members of the skeptical community that the paranormal and the supernatural do not exist. Unfortunately for those whose world would come crashing down if the paranormal were shown to be true, things that cannot be ex- plained rationally actually do happen, and have happened to me, (particularly in the week preceding 9-11-01), which is why I no longer consider the articles in SI magazine to be the final word on the subject. But it is still an informative magazine, which is fun to read. And, being party-poopers, the authors are used to being kicked around by those who want to believe. Once again, I have managed to escape the silliness that happens at midnight every year on this date. Instead of going out and acting silly, I'll sit by my fractal TV and watch others act silly. Until next year, which will be here sooner than one might expect, take care, and bide your time with a search for fractals.

Best concise definition of fractal ?
by Anna Baron 31 Dec '02

31 Dec '02

I'm curious to discover a really good explanation, in layman's terms, of what a *fractal* is - just a couple of sentences and no technical jargon. I don't know much about fractals myself: all I do is play around with Fractint a bit but formulas are a mystery to me. I've occasionally been asked what on earth these fractals are that grab part of my time, and I'm aware that whatever brief answer I've come up with was far from enlightening. I've no doubt any of you could do much better so I'd love to hear if anyone has a particularly good definition up his sleeve. A happy New Year to one and all!

FOTD 30-12-02 (The Power [4])
by Jim Muth 30 Dec '02

30 Dec '02

FOTD -- December 30, 2002 (Rating 4) Fractal visionaries and enthusiasts: When I first saw today's scene, which lies deep in the Mandelbrot set, it reminded me of something that I could not place. Then I noticed the eight straight sword-like features radiating from the central midget, and thought of the power- swords of the 'Star Wars' series. In a moment of inspiration I named the image "The Power". As I recall, the actual swords glowed greenish and didn't appear until they were needed for combat. But today's image comes just barely close enough to justify the name. Since it is merely another scene in the M-set, and something that has been seen many times before, I could rate it no higher than a 4. Hope- fully, tomorrow's FOTD will close the year in a better manner. The render time of 17 minutes can be avoided by downloading the pre-rendered GIF file from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> I see in the news that claims of the birth of the first human clone are circulating. The questions that are raised by the possibility are truly interesting, and will give me much philofractal material to ponder in the days to come. The weather here at Fractal Central on Sunday was of the fractal variety -- some sun, some clouds, little breeze, and a tempera- ture of 46F 8C, which is somewhat above normal. The cats were somewhat happy with the conditions in the yard, especially with the drying mud, but it's still quite muddy down in the holly thicket, so they avoided that area. For me, it's back to normal work today, but I will always manage to find time for fractals. Until next FOTD, which will appear in 24 hours, take care, and life is never dull as long as the world has fractals and clones in it.

Anna, Tim Wegner's book, "Fractals for Windows", says: " A fractal is a mathematical object that has detailed structure no matter how closely you look at it, no matter how great the magnification." I hope this helps. Bill Rossi <A HREF="http://members.aol.com/billatny">http://members.aol.com/billatny</A> <A HREF="http://www.arts4u.org/rossi">http://www.arts4u.org/rossi</A>

I quote from the book "Fractal Creations": Fractals are beautiful, fascinating designs of infinite structure and complexity -- the sort of intricate patterns that capture attention and evoke a sense of childlike wonder. A fractal is a *MATHEMATICAL OBJECT* that has detailed structure no matter how closely it is looked at, no matter how great the magnification. And also from the book: So what are fractals? As you make your way through this book, we will present ample evidence of the diversity of the universe of fractals and the multiplicity of ways of answering that simple question. I might add: fractals are graphs of reiterated mathematical functions. Fractals are pictures of the things numbers do. But even that is not really satisfactory. In truth, fractals are kind of a mystery, inhabiting as they do a world halfway between the objective and subjective. No one really knows why such simple mathematical expressions must lead to such complex results. Jim M.

investigations#2

Dear reader Sierpinski With the if-else feature of the formula parser it's easy to write a escape time formula for the Sierpinski triangle. I suppose someone have done that before. Nevertheless here is mine: formula#5 Jhsierpinski {;Jos Hendriks,2002 z=Pixel: IF (real(z)<.5 && imag(z)>.5) z=2*z-(0,1) ELSEIF(real(z)>.5) z=2*z-(1,0) ELSE z=2*z ENDIF |z|<p1 } I know pictures made with this algorithm. For instance there are some in "Fractals everywhere" (Barnsley). These pictures show the layers due to how long it takes for the orbits to escape. The Sierpinski triangle itself isn't really visible. I was curious if a better picture was possible. It turned out that 3 parameters were important: number of iterations, bail-out value and the colormap. Below is a parfile with an example witch gives a quite good impression of the triangle. With the possibilities of fractint there are with the formula another kind of pictures possible. I'm always eager to find "texture" like pictures. Pictures that has a kind of repetition, but doesn't reveal more details when zooming in. Below are two pars with examples. I wrote another formula, based upon those creating the Sierpinski triangle. You could call it a lambdaSierpinski formula: formula#6 Jhsierpinskim { z=Pixel: IF (real(z)<.5 && imag(z)>.5) z=(2*z-(0,1))*Pixel ELSEIF(real(z)>.5) z=(2*z-(1,0))*Pixel ELSE z=2*z*Pixel ENDIF |z|<p1 } The linearity of the formula gives parts of the plane, edged by straight lines. Some unlinearity( spirals etc) slips in cause of lambda. Below 2 parfiles as examples. For simplicity I put the frm's and pars below together. So it's easier to transport them together. All the pars take just a few seconds to render. p.s: When I rerendered the images from some of the pars below, the parser gives:can't understand the parameter color=etc. Nevertheless fractint shows the image, but it may use an other colormap then I intended. Because I created the pars in the usual way, I can't understand what went wrong. Anybody knows? frm:Jhsierpinski {;Jos Hendriks,2002 z=Pixel: IF (real(z)<.5 && imag(z)>.5) z=2*z-(0,1) ELSEIF(real(z)>.5) z=2*z-(1,0) ELSE z=2*z ENDIF |z|<p1 } frm:Jhsierpinskim { z=Pixel: IF (real(z)<.5 && imag(z)>.5) z=(2*z-(0,1))*Pixel ELSEIF(real(z)>.5) z=(2*z-(1,0))*Pixel ELSE z=2*z*Pixel ENDIF |z|<p1 } jhsiertriangle {;Jos Hendriks,2002 reset=2000 type=formula formulafile=sier.frm formulaname=Jhsierpinski passes=1 center-mag=0.475632/0.48248/1.850399 params=10000/0 float=y maxiter=100 colors=000<8>000000000<3>000zzz<88>zzz<4>zzzccc<143>ccc } lambdasier1 { ; Jos Hendriks, 2002 reset=2000 type=formula formulafile=alle.frm formulaname=Jhsierpinskim passes=1 center-mag=+0.54606658322903670/+0.12909227378964890/946.2815 params=10/0 float=y colors=000z02<15>j02<2>g02f02f02f02<55>O02O02N02<3>M020z2<15>0j2<2>0g20f\ 20f20f2<55>0O20O20N2<3>0M200t<15>00d<2>00a00`00`00`<61>00G } lambdasier2 { ; Jos Hendriks, 2002 reset=2000 type=formula formulafile=alle.frm formulaname=Jhsierpinskim passes=1 center-mag=+0.54887713642052600/+0.10850051419031680/445.3089 params=10/0 float=y colors=00000e0e00eee00e0eeL0eeeLLLLLzLzLLzzzLLzLzzzLzzz000555<3>HHHKKKOO\ O<3>ccchhhmmmssszzz00z<3>z0z<3>z00<3>zz0<3>0z0<3>0zz<2>0GzVVz<3>zVz<3>zV\ V<3>zzV<3>VzV<3>Vzz<2>Vbzhhz<3>zhz<3>zhh<3>zzh<3>hzh<3>hzz<2>hlz00S<3>S0\ S<3>S00<3>SS0<3>0S0<3>0SS<2>07SEES<3>SES<3>SEE<3>SSE<3>ESE<3>ESS<2>EHSKK\ S<2>QKSSKSSKQSKOSKMSKK<2>SQKSSKQSKOSKMSKKSK<2>KSQKSSKQSKOSKMS00G<3>G0G<3\ >G00<3>GG0<3>0G0<3>0GG<2>04G88G<2>E8GG8GG8EG8CG8AG88<2>GE8GG8EG8CG8AG88G\ 8<2>8GE8GG8EG8CG8AGBBG<2>FBGGBGGBFGBDGBCGBB<2>GFBGGBFGBDGBCGBBGB<2>BGFBG\ GBFGBDGBCG000<6>000 } sier1 { ; Jos Hendriks, 2002 reset=2000 type=formula formulafile=alle.frm formulaname=Jhsierpinski passes=1 center-mag=0.488878/0.841371/0.7771474 params=100/0 float=y outside=imag colors=000zzz<5>ttz<3>ppzpoypnxpmwplv<3>mhrlgqkfo<3>gbgfaed_caX_<2>PKPKG\ HGBNC9TD6ZC6`D6bD6dF5fF5hG5jH3lH3nH3pJ3rJ3tL1vJ3xH6zG9wFCvDFsCHrAKo9Nm7P\ l6Si5Vh3Ye2`d1ba0e`0fZ6ZSDRLKKGSC9Z53e000zOLR7l00k00i00h00f20e50d70dC0<3\ >ZN0YP0YS0XX1<3>Rf3Pi3Pm5<2>Lv6Ky7Jz7Kz5Jz7Hz9HyCGvDGsGFpHDmJDkLChNCePAb\ R9`S9YV7XX7UZ6R`5Oa5Ld3Je3Gh<2>17m05o02r00s00z00t20p52l93hD6dG7`KAXOCSRF\ OVGKzm0mY6YHGL0NJ0OH2PG6RFARDFSCJU9NV7RV<2>3bZ9VL5XJ2eZ0zm0to1mo6foAaoFV\ oKOpOJpUCpY5pZ1sa0pd0oe0mh0lk0il0ho0fr0es0bv0ay0`z0fz0Z<2>m0Di06e00b00d0\ 0e10f32h75iC9kFClJFmLHoPLpUOrXRs`UtdYvf`wkbymezrizvlzyozzrzztzzrwwpttopp\ lmmkkiifefdbeaZdzlK<2>KOlezp6Gv9JsCKrDNpGOmJPlKSkNUiPVfRYeUZdX`bYb``dZbe\ YdhXfiU<2>moPppNrsLttKzzKHzKGzLAzH<5>Zz`bzdfzfkziozm } sier2 { ; Jos Hendriks, 2002 reset=2000 type=formula formulafile=alle.frm formulaname=Jhsierpinski passes=1 center-mag=0.529848/1.20584/3.72083 params=100/0 float=y outside=atan colors=000zzz<5>ttz<3>ppzpoypnxpmwplv<3>mhrlgqkfo<3>gbgfaed_caX_<2>PKPKG\ HGBNC9TD6ZC6`D6bD6dF5fF5hG5jH3lH3nH3pJ3rJ3tL1vJ3xH6zG9wFCvDFsCHrAKo9Nm7P\ l6Si5Vh3Ye2`d1ba0e`0fZ6ZSDRLKKGSC9Z53e000zOLR7l00k00i00h00f20e50d70dC0<3\ >ZN0YP0YS0XX1<3>Rf3Pi3Pm5<2>Lv6Ky7Jz7Kz5Jz7Hz9HyCGvDGsGFpHDmJDkLChNCePAb\ R9`S9YV7XX7UZ6R`5Oa5Ld3Je3Gh<2>17m05o02r00s00z00t20p52l93hD6dG7`KAXOCSRF\ OVGKzm0mY6YHGL0NJ0OH2PG6RFARDFSCJU9NV7RV<2>3bZ9VL5XJ2eZ0zm0to1mo6foAaoFV\ oKOpOJpUCpY5pZ1sa0pd0oe0mh0lk0il0ho0fr0es0bv0ay0`z0fz0Z<2>m0Di06e00b00d0\ 0e10f32h75iC9kFClJFmLHoPLpUOrXRs`UtdYvf`wkbymezrizvlzyozzrzztzzrwwpttopp\ lmmkkiifefdbeaZdzlK<2>KOlezp6Gv9JsCKrDNpGOmJPlKSkNUiPVfRYeUZdX`bYb``dZbe\ YdhXfiU<2>moPppNrsLttKzzKHzKGzLAzH<5>Zz`bzdfzfkziozm } sier3 { ; Jos Hendriks, 2002 reset=2000 type=formula formulafile=alle.frm formulaname=Jhsierpinski passes=1 center-mag=0.527529/-0.153234/7.771474 params=100/0 float=y outside=atan colors=000<3>00n00z0C0<3>0Cn0Cz0P0<3>0Pn0Pz0a0<3>0an0az0n0<3>0nn0nz0z0<3\ >0zn0zzC00<3>C0nC0zCC0<3>CCnCCzCP0<3>CPnCPzCa0<3>CanCazCn0<3>CnnCnzCz0<3\ >CznCzzP00<3>P0nP0zPC0<3>PCnPCzPP0<3>PPnPPzPa0<3>PanPazPn0<3>PnnPnzPz0<3\ >PznPzza00<3>a0na0zaC0<3>aCnaCzaP0<3>aPnaPzaa0<3>aanaazan0<3>annanzaz0<3\ >aznazzn00<3>n0nn0znC0<3>nCnnCznP0<3>nPnnPzna0<3>nannaznn0<3>nnnnnznz0<3\ >nznnzzz00<3>z0nz0zzC0<3>zCnzCzzP0<3>zPnzPzza0<3>zanzazzn0<3>znnznzzz0<3\ >zznzzz000<12>fffiiimmm<3>zzz000<18>000 }

FOTD 29-12-02 (Pink Lemonade [5])
by Jim Muth 29 Dec '02

29 Dec '02

FOTD -- December 29, 2002 (Rating 5) Fractal visionaries and enthusiasts: For today's glorious image we travel to East Valley of a midget in the East Valley of a larger midget in the East Valley of a still larger midget in the East Valley of the midget at -1.75 on the stem of the M-set. All these East Valleys add up to a lot of East-Valley-type fractal elements surrounding the as-yet-un- seen midget at the center of today's rather deep lying image. When working with deep images such as today's, it is sometimes difficult to find the best place to crop the scene. As I study the image, I can see areas deeper down which, if cropped there, might make even better images. I also notice that today's image could have been better if I had backed farther out to avoid the cut-off elements. This problem exists at every level of the immense basin surrounding the midget. The only thing to do in such a case is to find an acceptable cropping and stick with it. The resulting picture does not equal the quality rating of 9 that yesterday's image earned, there was little chance that any image could, but its rating of 5 is at least in the average range. Its render time of one hour however is well above average, which is actually below average for convenience. The name I gave the image -- "Pink Lemonade" -- refers to the lemonade-like colors in the ring of cut-off elements. The GIF image will soon be available, completely rendered, on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather was fair enough here at F.C. on Saturday, with warm sun, light winds, and a temperature of 43F 6C. But the yard is still snow-covered, and the melting snow made conditions too sloppy for the sensitive paws of the dynamic fractal cats, who passed the day wishing spring would arrive. I passed the day being dragged around, looking for bargains and grumbling under my breath. Today is another day however, and maybe I can spend it doing something far more useful such as reading the latest issue of 'Skeptical Inquirer' magazine, which even after 20 years of showing the scientific way, has failed to cure me of my gullibility, credulity and superstitious beliefs. So look for me, still credulous and fractaling, at this same place in another 24 or so hours. Until that golden moment, take care, and when the going gets tough, the tough get fractaling.

FOTD 28-12-02 (Cascade of Bubbles [9])
by Jim Muth 28 Dec '02

28 Dec '02

FOTD -- December 28, 2002 (Rating 9) Fractal visionaries and enthusiasts: Somehow, I once again survived the first and biggest of the two seasonal holidays. (Is it politically correct to use the word 'Christmas'?) The tree was lovely, the turkey dinner delicious, the presents were exchanged peacefully, the conversation was not controversial, and most importantly, the fractal cats concealed their bad moods. All this pleasantness left me in a highly- charged fractal-finding mode. (Fractals are really not hard to find.) The fractal I found appears as today's FOTD image. The formula I used is an old one, which has been lying dormant for many years and which for some forgotten reason I had named 'cascade'. As is the case with most of these old formulae, I have totally forgotten what it was originally intended to do. (Why do I neglect to add comments?) The formula appears to have some vague relation to the mysterious 'Ikenaga' function, though I wrote it at least one year before I began working with the 'Ikenaga' function. The image that I found, with its rating of a very impressive 9, is one of the best of the year. Like so many works of art that unfold in time, the 2002 series of FOTD images has reached its peak near its end. I named the image "Cascade of Bubbles". I chose this name when I noticed that the bof60 bubbles appear to be cascading down into the depths of the picture. This cascading effect might be what inspired the original name of the formula, which, unlike most of my formulae, has no variable parameters. There are as many holly leaves as bubbles in the image, all cascading downward, but bubbles are more poetic, so I chose the bubbles. The image renders in exactly 4 minutes on my machine, accurate to 1/100 of a second. There is nothing unusual in this time. It is simply a coincidence. After all, a time of exactly 4 minutes has just as much chance of coming up as a time such as 0:04:16.37. The 4-minute render-time wait can be cut by more than half by downloading the finished GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> It was a cold week here at Fractal Central, with 4 inches of snow on Christmas day giving the first white Christmas in 33 years. Needless to say, the dynamic duo of fractal cats disapproved of such conditions and needed several treats of left-over turkey to soothe their ruffled tempers. As for me, I somehow have managed to get almost all the work caught up, and find myself with little to do but search for the next fractal, which will appear in 24 hours. It will be hard to find one that equals or exceeds today's image, but I'll try. Check tomorrow to see if I succeed. Until then, take care and relax.

investigations#1
by jos hendriks 28 Dec '02

28 Dec '02

Dear reader Intro About three or four years ago I downloaded fractint and winfract. Since then, every year, during wintertime I'm playing with those programs. It's the formula parser that has my main interest. I can subdivide this in three things: 1. What are the possibilities of the parser? 2. Do I understand what it is doing? 3. Can I produce pictures, which are somehow interesting and/or beautiful? Now I feel the need to show some of my "investigations" to people who are interested. I'm not sure this list is the right place, because emails I read are mainly about implementation-problems. Well, we will see. Quit normal, during my investigations, a lot of questions pop up. Questions I couldn't answer. Maybe someone can. Short formulas and graphs of real valued functions This first time I like to show is that you can make really short formulas. Here's one: formula#1 jhline { : |Imag(Pixel)|<p1 } I like it: there is no initiation, nothing in the looping part, there is only a criteria to stop. The formula draws the x-as. The thickness of the line depends on the parameter p1. So I ask myself: "What is the shortest, meaningful formula possible". I came with this: formula#2 jhshortest { : Pixel<0 } This formula divides the plane in two half-planes. Apart from the name there are 10 symbols. Naturally this gives my first question: question#1 Is there a shorter formula possible? Does anybody know a shorter one? Because Pixel=( , ) is a complex number or otherwise interpreted a point of the plain, the statement Pixel<0 has mathematical spoken no meaning: there is no ordering in Z or R2. Nevertheless the generator interprets the statement. So question#2 How interprets the formulagenerator things like z<1? For sure these formulas have nothing to do with fractals. But they have to do with fractint. And the first one gave me a marvellous idea (at least that's what I think): you can use the formulagenerator for drawing the graph of real valued functions in a rather simple way. Here are two formulas doing that. The first draws a parabola, the second draws the graphs of functions of the form f(x)=(ax+b)/(cx^2+dx+e) formula#3 jhparabola {;Jos Hendriks,2002 : |real(Pixel)^2-imag(Pixel)-1.25|<p1 } formula#4 jhgraphs1 {;Jos Hendriks,2002 ;graph of y= (a1*x+a2*x)/(a3*x^2+a4*x+a5)\ ;imag(p3) gives the thickness : |(real(p1)*real(Pixel)+imag(p1))/\ (real(p2)*real(Pixel)^2+imag(p2)*\ real(Pixel)+real(p3))-imag(Pixel)|<imag(p3)||\ |real(Pixel)|<.001|||imag(Pixel)|<.001 } In these formulas is the amount of typework not greater then in a "math-program". The rendering time is not too long: a few seconds or less. Moreover, and I think the most interesting part: The unusual way fractint draws the graph (it's scanning if a point belongs to the graph or not) makes a graph a quite elegant drawing because the thickness of the line is not everywhere the same. So you can create elegant curves. About this maybe another time. For convenience I have included some parameter files, because some picture parameters are important. For instance maxiter=2. I have the frms also repeated. In this way you can transport all at once into a par file. p.s:don't blame me for mistakes I make in writing English: it's not my native language frm:jhline { ;Jos Hendriks,2002 ;draws the line y=0, p1 gives the thickness of the line ;watch out: only two colors are used ;take for instance maxiter=2, inside=0, outside=iter : |Imag(Pixel)|<p1 } x-as {;Jos Hendriks,2002 reset=2000 type=formula formulaname=jhline center-mag=0/0/0.6666667 params=0.001/0 float=y maxiter=2 inside=0 colors=00000e } frm:jhparabola{ ;Jos Hendriks,2002, ;draws a parabola.

Re: [Fractint] laptops and video card
by Kathleen.Roth＠kp.org 25 Dec '02

The troubles are unrelated to this question - had software problems with Netscape and then the fan died, probably related to dog hair and it cooked the CPU. They were able to replace it and most of my hard drive is ok. But now there are problems with the video card which might just be from being joggled loose as it goes back and forth to the shop. I forget what video card I have but it was recommended by people on this list 3 years ago. I have been thinking about getting a laptop for some time just as a backup. I am running Windows 98 on a Pentium 500 with I think 156 RAM- have been very happy with it so was not thinking of changing. It's got lots and lots of disc space left. The computer is in the consultant's shop and I am at work so I don't have all the info- hope you're all having a nice holiday. Thanks Kathy What are the troubles you are having? What operating system (version and release) are you using? How much RAM do you have? How much free disk space is available? > > I also was thinking of getting a laptop as a backup. What OS will you be wanting on your laptop?

FOTD 22-12-02 (Batty for Fractals [6])
by Jim Muth 22 Dec '02

22 Dec '02

FOTD -- December 22, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's image comes as close to true-color as is possible with only 256 colors. The iteration bands are still there, but one must look carefully indeed to see them. And no, I did not spend hours working on this illusion. It happened by accident as I was rotating the palette. I named the image "Batty for Fractals" because the dark objects in the foreground remind me of baseball bats. The generating formula is named "BackwardBrot" because instead of raising Z to the power of a number, it raises a number to the power of a power of Z. I wrote the formula many years ago, well before I started the FOTD, back in the days when I was an intrepid fractal explorer exploring alone where no one had gone before. I am still a fractal explorer, and always shall be, but as the world of fractals has become more familiar, I no longer need to be as intrepid as I once was. The sense of adventure is still there however, and as long as unseen things remain in the world of fractals, I shall seek to find them. Partly because of its illusion of true color, which might depend on the adjustment of the individual monitor, today's image rates a 6. Perhaps its best feature is its incredibly fast render time of 48 seconds, which is likely due to the fact that its magnitude is in the default range. The completed GIF image may be found on the W.W.W. at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> With a temperature of 55F 13C, Saturday turned out to be better than expected here at F.C. After starting with lots of clouds, it turned sunny and mild by noon. Too bad that the holly trees blocked most of the sun from reaching the yard, where the dynamic duo spent almost two hours exploring. I fail to see how one's own yard can be so unknown that it needs to be explored, but then I am not a cat, and cats live in a different world. Now I must give the bad news that I had hoped to avoid. With the holidays so close, things are getting so hectic here at F.C. that for the next few days I will be unable to find the time for fractal exploration. As a result, today's FOTD will be the last until this coming Saturday, December 28. But I am not losing enthusiasm for fractals -- I can't imagine that happening -- I merely will not have the spare time to sit at the computer and explore. Until Saturday then, take care, and I'll still be checking the lists every day.

FOTD 21-12-02 (Art-Nouveau Midget [6])
by Jim Muth 21 Dec '02

21 Dec '02

FOTD -- December 21, 2002 (Rating 6) Fractal visionaries and enthusiasts: December is supposed to be a month without quadratic midgets. This does not mean it is a month without near-quadratic midgets however. The midget at the center of today's image has in itself small imperfections that indicate it was generated by the formula Z^2.003+C rather than Z^2+C, so the quadratic-midget- free month continues. If yesterday's image had a bit of an art-nouveau feel about it, today's image looks like it came right out of 1898. What could I name it other than "Art-Nouveau Midget"? The image was generated by the MandelbrotBC1 formula, which calculated the parent fractal as it appears 1050 levels up the logarithmic spiral, where it is rotated 180 degrees, causing the negative X-axis split to fall on East Valley, which is now on the west side of the origin. I needed to go up 1050 levels because with the exponent so close to 2, the fractal changes very slowly as we depart from ground level. Today's arty scene is located in an area of fractured chaos at the edge of its parent's rotated East (or West) Valley, which is just starting to broaden and split. This area holds a horde of other midgets, many of which might be far better than today's. But it would take forever to track down all of them, and I have little time to spare. The image rates a 6, which is a little above average. It renders in 11 minutes, which is a little below average. And it downloads from the FOTD web sites in around one minute, which is always average. Those web sites may be accessed at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Friday began mild and showery here at Fractal Central, but around midday the rain stopped, the breeze picked up and the sun appeared. The unusually warm temperature of 57F 14C lured the cats into the yard even before the grass, or what is left of it, had completely dried. By the end of the day their moods were actually pleasant enough to bring purrs. For me, the heavy work continues uninterrupted. And I also have a number of gifts yet to find. It's looking like I may have to miss a few days' FOTD's next week, but at least tomorrow's will appear on schedule. Until then, take care, and a fractal a day is one of the best ways to keep off that extra weight.

FOTD -- December 20, 2002 (Rating 5) Fractal visionaries and enthusiasts: For today's FOTD I unpacked a formula named MytestAF. I have no idea what the name means or what the formula is supposed to do. I wrote it one day a number of years ago when I was inventing formulas (formulae for the over-educated) at random, hoping for a lucky break. But the lucky break never happened, and the formula was consigned to one of my abandoned formula files, where it has languished for 6 years or so. On Thursday, after being dead all that time, the formula was chosen at random and given one last chance. It seized the chance and created an image that, rating a 5, barely made it onto the honor roll of FOTD images. It is a busy, jittery looking image, which is why I named it "The Jitters". The foreground is filled with curved bits of brilliantly blue debris that arranges itself into yellowish angular masses as it fades into the background. This background debris is just that -- debris. When enlarged, it does nothing, and goes on apparently forever doing nothing. It lacks even the curvilinear, art-nouveau-like, feeling of the foreground. On my nearly-extinct machine the attached parameter file runs in 2-1/2 minutes. On a real 'screamer' it will run in a minute or so. The completed image will download in less than a minute from one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> But, for those who are not always connected, another minute or so will be spent going online and reaching the sites. Since all means of viewing the image are about equal in time spent, it is up to the individual fractalist to decide which route to take. Well, the holiday season is almost here -- the darkest time of year in the northern hemisphere, when I am most prone to wax philosophic about many things, but the shortcomings of science and technology in particular. And when I do such waxing, I usually get myself into a lively debate with those who feel that science might be threatened and needs to be defended. Luckily for members of the Fractint list, if the philosophizing starts, I will confine it to the philofractal list, where it will be on-topic for anyone who might still be there to listen. Thursday continued the cloudy, chilly, damp weather here at F.C., with a temperature barely reaching 40F 4C. Seeing such conditions, the cats were no happier than they had been the Wednesday before. As for me, I have much work to do and little time in which to do it, and the new work keeps coming in. I hope to keep the FOTD going every day through the holidays, but it is by no means certain that I will be able to do so. Tomorrow's fractal will appear on schedule however. After that we'll have to take it a day at a time. Until next FOTD, take care, and, if possible, be cheerful until the holidays are past.

FOTD 19-12-02 (Corrected Super-Bridges [5])
by Jim Muth 19 Dec '02

19 Dec '02

FOTD -- December 19, 2002 (Rating 5) Fractal visionaries and enthusiasts: This is a corrected version of the already-posted FOTD. I inadvertently left the semicolon out of the comment line of the formula in the first version. A few days ago, Tim posted a question about three-part numbers, or triternions. Shortly thereafter, Morgan posted a basic formula that draws the triternion Mandelbrot set, which, as drawn by the formula, consists of a skewed M-set with its northern part chopped off. When I ran the formula, I was expecting a somewhat different figure, but I'll take whatever the numbers give. (Maybe several varieties of three-part numbers are possible, and one of the other varieties would draw a different M-set.) Adding a few simple variable parameters to the formula, and giving it a new name, I did a little experimenting, and found that the triternion M-set behaves much like the hypercomplex set. It seems to consist of overlapping M-sets with straight 'bridges' added. Unlike the bridges in the odd planes of the Z^2+C Julibrot, which consist of stretched elements and can be unstretched into recognizable figures, the bridges in the triternion set consist of truly one-dimensional elements, which no amount of stretching will make into recognizable figures. In the triternion set, as in the hypercomplex set, different elements often overlap, and when this happens, the element with the lowest iteration count will prevail. Today's image shows triternion bridges overlapping conventional M-set elements, with a Minibrot on the left and a spiral on the right. The resulting interplay produces some interesting 3-D effects, especially around the spiral. I named the image "Super-Bridges" on a whim. Not knowing quite what to make of the image, I rated it at an average 5. Regardless of the rating, the image is a fast one, requiring only 2 minutes to render from the attached parameter file The image can also be seen by downloading it from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Partly cloudy skies on Wednesday could not make up for a raw east wind and a temperature that barely rose above freezing. The fractal cat Tippy expressed his displeasure by sulking. Thomas was too busy sleeping by the heat. And if I don't soon get busy, a few customers will be sulking. So until next time, which will arrive on schedule in 24 hours, take care, and keep careful watch for the spirit of the season.

FOTD 18-12-02 (Final FMOD [4])
by Jim Muth 18 Dec '02

18 Dec '02

FOTD -- December 18, 2002 (Rating 4) Fractal visionaries and enthusiasts: Things have been quite busy recently here at F.C. The reason is the season. To save time, I have taken one more trip to the world of <fmod>, and found another image composed of all-inside stuff. This image looks rather like a flower, but not enough like a flower to give it a flowery name. The name I finally gave it -- Final FMOD -- is an admission that, though this recently discovered world of <fmod> inside fill might be infinitely complex, I lack the time at the present to give it the exploration necessary to find the great images that certainly lie therein. As a result, I shall make today's image the last in the present series of images. (And I'm also getting interested in that triternion formula Morgan recently posted.) The render time of today's image is once again in the 11-minute range, which is not surprising, considering that the past three images have consisted totally of inside fractal areas of the same formula, and were rendered with the periodicity turned off. The finished GIF image will soon be posted on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: . . . <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> . . . ready for download. Tuesday was chilly but sunny and calm here at F.C. The cats must have approved of the 36F 2C temperature, for they spent almost two hours in the yard. I'll need to spend a bit more time than that if I hope to end the day with an empty 'to be done' shelf. So the best time to start is now. Until next time, take care, and don't be empty inside.

FOTD 17-12-02 (FMOD Mushroom [4])
by Jim Muth 17 Dec '02

17 Dec '02

FOTD -- December 17, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's image is another venture into the strange fmod world of yesterday's image. True, the parameters have changed a little, but the effect is the same. The fmod fill normally draws bubble- like shapes. It has no right to draw things like the nest of Sierpinski triangles that appears in today's image. But the image does not lie -- the shapes are there. Maybe the unusually high proximity setting of 8.5 is responsible for the madness. I don't know the answer, but after the holidays I will certainly do more investigation into this phenomenon. I must also work out a method of coloring these images. The all-or-nothing palette I used in today's image is the best I could find so far, but there are many things I have not yet tried. The many artistic shortcomings of today's image drag its rating down to a 4. This less-than-average artistic rating is somewhat offset by the mathematical potential that lies in the image. I have named the picture "FMOD Mushroom". A quick glance will show why I chose this name. The render time of 11 minutes can be avoided by downloading the completely-rendered GIF file from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday was sunny, and the temperature reached an unexpected high of 46F 8C, but the winds were far too high for outdoor comfort. After a brief time sitting on the porch, the dynamic duo decided to pass the afternoon indoors next to their favorite radiators. And I'm going to pass this day working and preparing for the holiday season and all the marginally necessary activities that accompany it. Until next time, take care, and prepare.

FOTD 16-12-02 (The FMOD Fill Wins [5])
by Jim Muth 16 Dec '02

16 Dec '02

FOTD -- December 16, 2002 (Rating 7) Fractal visionaries and enthusiasts: I have long suspected that the < fmod > fill has more potential than a hasty trial would indicate. Yesterday, I found that this is indeed true. I named today's image "The FMOD Fill Wins", because I feel that it reveals the full potential of the < fmod > inside fill, which I expect to be using more of in the future. With no inside fill, the parent fractal of today's image would be a circle with a totally blank and empty interior, and today's image itself, which consists entirely of trapped inside points, would show nothing more than a flat black screen. Another big contributor to the unusual effects seen in today's image is the < cosxx > function, which is actually an old mistake retained for compatibility. The final contributor is my Mystic2 formula. I wrote this formula a number of years ago for some reason which I have long ago forgotten. It draws nothing but empty circles unless a non-flat inside fill is applied. Because it is different, I have rated today's image at a 7. If I had found more time to color it, I might have found a palette that raised the image to an 8. The 11-minute render time is a bit slow, but a download of the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> can shorten the wait. Sunday turned out to be the warmest day of the month, with a temperature of 50F 10C. This was just what the dynamic fractal duo needed to give them the pleasant day outdoors that restored their kittenish good humors. But today is much colder, so I wonder how long those good humors will last. My humor is not too bad, but will improve still more when the work is finished. Until next FOTD, take care, and be mod.

FOTD 15-12-02 (Midget in a Nebula [7])
by JimMuth＠aol.com 15 Dec '02

15 Dec '02

FOTD -- December 15, 2002 (Rating 7) Fractal visionaries and enthusiasts: I rather admire today's image, with its elements half obscured by illuminated haze. It reminds me of one of those nebulas in space, where stars are being born. Because of this resemblance, I named the image "Midget in a Nebula" and rated it at a 7, a rating that, in my opinion at least, is fully justified. Yes, I realize that December was supposed to be a month without a quadratic midget. So I lied -- so what! Today's image is a good fractal, one well worth having the honor of FOTD bestowed upon it. Most of the image consists of bof60 inside fill. The generating expression combines various portions of Z^(1.8), Z^(-0.8), Z, and Z^(0.8) before adding 1/C. The work was done by my unused MandelbrotMix3 formula, which combines 4 different powers of Z but leaves it to the fractalist to work out a critical point to enter as the real(p5) parameter. Because of the work involved, and because the images are not that much better than those created by the M-Mix4 formula, I rarely use the M-Mix3 formula. The render time of 17 minutes is a bit slow. Time may be saved by downloading the finished image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Saturday was blustery here at F.C., but there was enough sun to warm it to 47F 8C, which pleased the fractal cats, who managed to enjoy an hour of yard time chasing the few sunbeams that filtered through the holly trees. A treat of chicken in the evening completed a pleasant day for the fractal duo. Well, I made it through yesterday's shopping, and I'll likely make it through today's also. Then, when the day is done, I'll concentrate on the next FOTD. Until tomorrow, take care, and when is a fractal not a fractal?

FOTD 14-12-02 (The Blade [5])
by JimMuth＠aol.com 14 Dec '02

14 Dec '02

FOTD -- December 14, 2002 (Rating 5) Fractal visionaries and enthusiasts: With much shopping to get done before the day ends, I will have to make today's FOTD discussion a fast one. Today's image pictures an enigma. "How can it be like that?" I ask myself as I study the image, which combines both Julia and Mandelbrot features of the (-Z)^2.003+C Julibrot. The scene is located in the East Valley area of the large midget on the split-up main stem of its parent. The outer part of the image is in the shape of a slightly distorted typical-East- Valley Julia set. Since the direction of the slice is slightly rotated from the exact Julia orientation, this distortion is to be expected. But the outer almost-Julia set is filled with the grossly stretched and enlarged apparition of the East Valley of the Mandelbrot midget itself. I do not know how it can be like this. It is a mystery. How can one look through an open Julia set and see an enlarged part of the Mandelbrot set? I know well enough how the numbers work to create the four-dimensional whole, but to picture that four- dimensional whole is as impossible to me as knowing the future or changing the past. I can comprehend it; I cannot see it. This mystery, this enigma, is what keeps me fascinated with fractals. To be so close to visualizing, yet stopped by my natural limits is frustrating, but at the same time, fascina- ting. Reading the books written by others who share my frustra- tion leads me to realize that the future is hopeless. Neither I nor anyone else shall visualize a four-dimensional object as it exists in its entirety in its own space at a single moment of time. And if anyone were to actually visualize something as simple as even a hypercube, that person could do no more than describe the arrangement of its parts -- a thing that we already know. The visualization would be impossible to communicate. I named today's image "The Blade". The distorted greenish object visible in the open area does resemble a blade. I rated the image at a 5, which is average. The render time of 3-3/4 minutes is also about average. And for those who would rather not render, the completed image can be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and downloaded from there. The rain arrived at 1pm on Friday, and fell steadily for the rest of the day. Despite the chilly temperature of 39F 4C, the fractal cats managed just enough outdoor time before the rain began to keep them happy until evening. This morning is once again threatening rain, and I can no longer put off the shopping that is unnecessary yet necessary at this time of year. But this evening, when the running around is behind me, I'll turn once again to fractals and the worlds that numbers create. Look for the next fractal in 24 hours. Until then, take care, and don't be too busy to enjoy the day.

Even my Jurassic 486 with Award BIOS has settings for monitor, hard drive, and CPU inactivity timeouts. If your CPU timeout is enabled, disable it; the "sleep" mode operates based on user interaction rather than CPU activity (I'd like to throttle the guy who made *this* judgement call).

Xfractint, colors & screenupdates
by Natalie 13 Dec '02

13 Dec '02

Hello again, One week passed without any reaction, so I'll try again. (Slightly edited version of previously sent message.) Dear, admirable programmers, would it be possible to add a colormap editor to Xfractint? Please?? I tried another fractal generating program for Linux, Gnofract4D. It can't compete with Xfractint, although it has some nice features. It has an evolver-mode (9 images), zooms in and out, there are 9 fractal types, some extra parameter functions, but the nicest feature is: the changing of colormaps (it uses Fractint colormaps!), the fractal is not regenerated (as in Xfractint), the colors are changed instantaneously (like in DOS Fractint). It is possible to edit colormaps in The GIMP and use them in Xfractint. The GIMP also has a gradient editor, which has even more editing features, but gradients have to be converted to palettes to use them in Xfractint. The colormap editing is still very tedious, you can't see directly how the colors turn out in the fractal image, Xfractint has to regenerate the fractal and if the result is not what you want, you have to go back to The GIMP and edit the map again. If the fractal takes a long time to generate, it might be days before you've obtained the result you want. Another possibility is to change the colors of the image in The GIMP, the image will be updated at once, but all Xfractint info will be lost. This is not a problem if you just want to have a nice image, it will be a problem when you want to zoom in or manipulate the fractal with the edited colormap in any other way in Xfractint. Other image manipulation progs, like Electric Eyes and Pixie can be used for color changing, and they too will update the screen immediately. So..., the code to edit colors of an image does exist, moreover the code is open source. >From The GIMP help file: The GIMP is an OSS (Open Source Software) program covered by the GPL License, which gives you the freedom to access and also to change the source code that makes up the program. Gnofract4D, Electric Eyes, and Pixie are all distributed under the GNU General Public License. Thanks Natalie -- Stolen tagline: Linux is like a wigwam, no windows, no gates, apache inside.

Fast and... slow
by Richard Giroux 13 Dec '02

13 Dec '02

Hi, Just a (maybe) technical question... I have observed that on many ".par" (from fotd) projects that are rather slowly rendered on my computer, there is an "accidental" way to speed up the rendering. That is just by pressing a key (which has no function in fractint, like "shift", to not disturb otherwise the rendering). The effect is that the rendering process seems to speed up for a while (one or two lines of pixels), then slows again. Is it caused by some memory settings ? I am under WinNT4, P3 / 533MHz, 576 Mb of RAM. Of course, Fractint20 runs under the DOS window of my WinNT. Thanks, RG ------- Un message en attend toujours un autre...

FOTD 13-12-02 (An Unreal Object [6])
by Jim Muth 13 Dec '02

13 Dec '02

FOTD -- December 13, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today is Friday the 13th here at Fractal Central. Am I worried about bad luck? Not in the slightest. I doubt that bad luck exists. What passes as bad luck is probably nothing more than normal statistical variation. But I admit that fate seems against me during those spells when, regardless of how long and hard I search, I can't find a good fractal anywhere. With its rating of 6, today's fractal is leaning toward good, but closer to average. In yesterday's FOTD discussion I told of a curious rectangular hole in one of the Julia sets of the Z^2.003+C fractal. Today's image shows that rectangle, not in its pure form, but slightly distorted by a double rotation. I have also added interest by filling the open area with < fmod > inside fill. The result looks rather artificial, even unreal. It appears to have been assembled from several fractals, which is why I named it "An Unreal Object". The entire image gives the impression of a surreal bird flying toward outer space, moving so rapidly through the atmosphere that it is actually ionizing the air as it moves through. The violet glow surrounding the bird-like shape could be a result of this ionization. I almost named the picture "Sunbird" after an old computer animation of a bird in space, flying beyond earth on its way to the sun. When viewing this short animation, I have always wondered how a bird can maneuver in the vacuum of space, with nothing to beat its wings against. Well, if those space fighters in the "Star Wars" series can do impossible things like turning and banking in a vacuum, why not a bird? The four odd perpendicular aspects of this area each have their unique features, and the odd oblique slices also hold some inter- esting scenery. But none are as interesting as the Mandelbrot and especially the Julia aspects. In its Mandelbrot aspect, today's scene is located in the East Valley area of the prominent midget on the main stem of its parent fractal. But in this parent fractal, created by Z^2.003, the main stem, including the East Valley of the midget, has started to split apart, revealing some entirely new material, including a curious tiny bay right on the X-axis. To see the 'unreal' bird that in today's image flies into space, boot Fractint and run the attached parameter file. After a wait of 7 minutes, the bird will be in full view, violet aura and all. Or the wait can be avoided by downloading the pre-rendered GIF image from the internet at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Thursday was a cloudy day here at F.C. The temperature of 45F 7C was reasonable enough, but the combination of snow and mud in the yard kept the fractal cats confined to the porch. Their moods were surprisingly pleasant considering the situation. Today is once again cloudy, with rain threatening. It remains to be seen how the dynamic duo will pass the day. I know how I'll pass my day -- keeping busy. And at 11:15am, it's already past the time to start. So until next FOTD, take care, and keep fractaling.

I assume it is caused by NT thinking the program is idle, so it is lowering its priority. This is necessary since many DOS programs, even though they look idle, are continuously polling the keyboard. If NT didn't lower the priority, it would kill system performance. I am guessing NT doesn't realize fractint is actually doing anything and it thinks it is just polling the keyboard. I never solved this problem - since I could only get fractint to work at 320x200x256 on my NT system, I hardly ever used it. Anyway, go into the properties for the DOS program (fractint) and try moving the 'Idle Sensitivity' slider all the way to 'Low'. Nick

FOTD 12-12-02 (Firefall [6])
by Jim Muth 12 Dec '02

12 Dec '02

FOTD -- December 12, 2002 (Rating 6) Fractal visionaries and enthusiasts: Fire and brimstone fill today's image, as an erupting fractal volcano on the left spews its fiery ejecta high into the atmosphere and over the cliff at the right edge of the frame. In the cloud of debris near the right edge lies a tiny object resembling a midget M-set. The resemblance is only superficial, for at the odd angle of today's image, no midgets are possible. The image is an odd slice of the open rectangle that appears in the C=-1.7435,0.0 Julia set of the Z^2.003+C fractal at Z coordi- nates 0.00019,0.07388. This unexpected and near perfect rectan- gle is one of my favorite fractal objects, one to which I often return. Its actual four-dimensional shape would appear to a 4-D person as a 2-D hole, with two extended dimensions and the remaining two dimensions very small, much as a sheet of paper in our 3-D world has two extended dimensions and one small dimension. Since two of its four dimensions are so small, this open area appears as a rectangle only when sliced in the Julia direction and at the exact C coordinates. The slightest rotation or imag(C) deviation totally destroys its straight edges and sur- rounding symmetry. At today's angle, the symmetry is totally destroyed. I named the image "Firefall" because, with a little imagination, it shows fire spewing from the ground and falling over a cliff. Others may see something else, but the falling fire is all I can see. The rating presented little problem. The slightly-above- average 6 seems just right. The image is a fast one, requiring only 2-1/4 minutes to render from the parameter file, on my worn-out machine. About the same time will be required to go online and download the completed GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Freezing rain, followed by heavy rain and melting snow brought flooding, fallen trees, power outages, and a roof leak to the Fractal Central area Wednesday. By evening, the high tempera- ture of 36F 2C had melted most of the ice that had built up on trees and sidewalks. Conditions were so bad outdoors that the intrepid cats were thankful to be permitted to remain indoors all day. The roof leak will require further investigation. Today is starting much improved, but I expect a lot of work before the day is finished, which might cut into my fractal time. To see how things work out, check back here in 24 hours, when the next FOTD will appear almost by magic. Until then, take care, and beware of fractal brimstone.

FOTD 11-12-02 (Spirals Without End [3])
by Jim Muth 11 Dec '02

11 Dec '02

FOTD -- December 11, 2002 (Rating 3) Fractal visionaries and enthusiasts: Today's fractal might show actual new material in the hypercom- plex Mandelbrot set, or it might be an artifact of mathematical imprecision. But regardless of what it is, it's an image with spirals everywhere. There are single spirals, double spirals, even signs of triple spirals. In fact, the image is filled with spirals without end. And "Spirals Without End" is what I named it. The image is a zoom into a hidden valley that appears peeking between the converging straight arms of yesterday's "Hyperbud" image, where a new world appears to be only partly revealing itself. In contrast to yesterday's image, which suffered from resolution breakdown, today's image suffers from the near impos- sibility of finding an acceptable coloring. I finally settled on a very broad purplish palette, though the result still leaves much to be desired and drops the rating to a below-average 3. While fractaling, I sometimes wonder about the meaning of it all. Is the existence of fractals filled with a deep, as-yet- undiscovered meaning, perhaps about the nature of reality, or are fractals mere candy for the eyes? And what of the concept of meaning itself? Is it something invented by the highest known form of life on the planet Earth, or is the universe filled with it? Does meaning actually exist before a self-aware entity asks the question 'why'? Does meaning exist on a two- mile-wide chunk of ice orbiting in the cold loneliness of the Oort cloud, where observers never have and never shall venture to ask 'why'? And what of this fourth dimension with its hyper-objects? We can infer exactly how the various parts would fit together if it existed, but even knowing these things, we cannot visualize some- thing as simple as a tesseract. Does this mean that the fourth dimension does not exist? Does it mean that it does exist but we cannot visualize it? Does it mean that we have invented the whole puzzle as a mental exercise? Or does it mean anything at all? Don't expect answers any time soon. And don't expect an image soon if you try to run today's para- meter file. It takes 1-1/4 hours on my less-than-supersonic P-200 machine. The best way to see the puzzling image is to download it from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Tuesday's fractal weather was cloudy and chilly here at F.C., with a high temperature of 34F 1C. The ex-dynamic duo passed the unsatisfactory day lounging by the heat, except for when they were asking for food. This morning has brought freezing rain, which is even worse. It's a good day to remain indoors and get ahead on some work. Until tomorrow, when things will hopefully be more pleasant, take care, and try to make the best of bad situations as they arise.

FOTD 09-12-02 (The Nest [6])
by Jim Muth 11 Dec '02

11 Dec '02

FOTD -- December 09, 2002 (Rating 6) Fractal visionaries and enthusiasts: Well, fractal persistence paid off, and I finally found an image worthy of an above-average rating. True, it's only a slightly- above-average rating of 6, but it's still an above-average rating, and that's all that matters. I might have rated the image higher if it had been something I found rather than created with the < epsiloncross > inside fill feature of Fractint. But let's not quibble -- an above-average image is an above-average image, and I needed an above-average image. (Having repeated the phrase 'above average' a sufficient number of times, I shall mention it no more.) The expression (-Z)^(1.5)+C was iterated to draw the fractal. Iterating -Z instead of Z merely reveals a different part of the infinite complex logarithmic spiral. The 'SliceJB-new-min' formula is a slight reworking of a formula that was posted to the list several years ago by John Goering. Today's image is an oblique slice of the -Z^1.5+C Julibrot. The slice is oriented rather close to the Julia direction, which is revealed when (p1) and (p2) are set to 0.5,0.5. I named the image "The Nest" when it reminded me of some crazy bird's nest. With its effect of being illuminated from behind, the image could just as easily been named something inspirational such as "Crown of Thorns". The 'SliceJB-new-min' formula draws more rotations than any other formula in my vast and partly forgotten collection, but it does not draw every possible rotation in four dimensions. Finding a formula that does this is still one of my quests. The render time of 18 seconds is blazingly fast, but the down- load of the completed image is still available at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Sunday was pleasant enough, with hazy sun, gentle breezes, and a temperature of 48F 9C. The problem was that the snow turned wet and slushy -- far too unpleasant for the cats' tender paws. They once again passed the day keeping warm and wishing they could get outside to play. This morning the snow has re-frozen and is dry, but the tempera- ture is well below freezing -- far too chilly for the intrepid ones. Having a pile of work to think about, I shall give the cold little notice -- that is unless some reason arises that I must wander outdoors. Until the next FOTD appears in 24 hours, keep warm or cool, whatever the case may be, and keep your fractals dry.

Triternnions
by Tim Wegner 11 Dec '02

11 Dec '02

Does anyone know anything about these beasties? I haven't had a chance to read this in depth yet, but they appear to be 6 dimensional cousins of quaternions/hypercomplex numbers. Could probably define trig functions for these, and get some fractals out of them (there's a Mandelbrot example in the article.) The question is, would there be more to discover that is not already present with hypercomplex and quaternion slices? http://fibonacci-arrays.com/Triternions.pdf Tim

FOTD 10-12-02 (Hypercomplex Bud [5])
by Jim Muth 10 Dec '02

10 Dec '02

FOTD -- December 10, 2002 (Rating 5) Fractal visionaries and enthusiasts: I see that the existence of triternions has been noticed. I had not seen them mentioned until Tim mentioned them in his recent letter, though I had assumed that they did exist and were less well-known mainly because they are less useful than quaternions. Three-part numbers would draw a three-dimensional Mandelbrot set and a six-dimensional Julibrot. But I wonder whether they would actually create new Mandelbrot material. The Quaternions and Hypercomplex numbers draw interesting Julia sets, but merely expand and distort the Mandelbrot set, introducing little if any actual new material. This might be due to the nature of the M-sets or it might be due to the way they are implemented in the program. I question the implementation because the Julia versions of the hyper-sets have 6 parameters, while the Mandel versions have only 2 working parameters. The quaternions draw a figure resembling the 3-D figure that would appear if the M-set were rotated around its X-axis. This figure, which basically consists of circles, can then be sliced through any of its parts, but the result is always a stretched and distorted version of the same Mandelbrot set that we know and love. The Hypercomplex M-set appears as two separate sets that overlap. Some interesting things happen where the two sets intersect, but once again, no new material is created. Perhaps the triternions would create a M-set with new material to explore, perhaps not. I rather suspect the latter, though it would be most interesting to actually try it and find out. Several years ago, bored with the sameness, I wrote a generaliza- tion of the Hypercomplex formula that does create new material. I have never been convinced that this new material is real rather than an artifact of mathematical imprecision, but it exists in a consistent way that would imply that it is indeed real. Today's image, which was created with this formula, and rather resembles a skewed gothic window with converging bars before it, has been named "Hypercomplex Bud". I gave it this name because it is a bud in the Hypercomplex Mandelbrot set unlike anything that appears in the familiar complex M-set. Not only is the image unique on the surface, but its inner details are surpris- ingly complex -- more intricate than anything that appears in the traditional M-set. I will show some of this incredible inner richness in tomorrow's FOTD. I had to rate today's image at an average 5. Its mathematical interest is above average, but its artistic merit is below. My alibi, as always, is lack of time. If I had more time, I could have found a better color palette. With a render time of 2/3 hour on my machine, the parameter file is a slow one. A far better way of viewing the scene is to download the finished GIF file from the internet and Paul's site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday was sunny but cold here at F.C. With snow on the ground and a temperature that never reached freezing, (it stopped at 28F -2C), the dynamic duo of fractal cats spent the day huddled by the heat. Late in the afternoon, a treat of turkey eased their distress, and consequently my distress also. As is usually the case, I find myself with several non-fractal tasks to accomplish before setting out on my fractal journey of the day. This is a certain sign that I must now get busy. So until next time in 24 hours, take care, and when you walk with fractals, don't expect much conversation.

FOTD 08-12-02 (Arcing [4])
by Jim Muth 08 Dec '02

08 Dec '02

FOTD -- December 08, 2002 (Rating 4) Fractal visionaries and enthusiasts: I named today's image "Arcing". My excuse is that the bluish streaks surrounding the central area of activity could be interpreted as a series of electric arcs. The actual reason is that I rather enjoy using the word, which regardless of how it is spelled, never seems to be spelled correctly. The presumed correct spelling is 'arcing', but spelled this way, the word looks as if it should be pronounced 'arse-ing', which more sensitive fractalists could take to mean something un-nice. The spelling 'arking' looks as though it would be pronounced correctly, but seems unrecognizable when seen on paper. The participial form of the word 'picnic' is 'picnicking', and this word gives no trouble. Why then can not the participial form of the word 'arc' be spelled 'arcking'? . . . I guess it looks like a mis-spelling of 'racking'. This little side trip into the world of correct spelling is in no way meant to divert attention from today's image, which is rated well above yesterday's lowly 2, but still comes in at a slightly-below-average 4. The slit-like hole at the center is actually a very odd slice of a midget that appears in the east valley area of a larger midget that lies on a filament extending from the northwest shore of the main bud of the M-set. At this angle, the 2,4,8... series of elements has basically disintegrated into a disorganized chaos, though the overall pattern is still rather well defined. A glance at the < tab > screen will show that the image has been greatly stretched and skewed to undo the inherent stretching and skewing of the scene. Such stretching and skewing is an important part of examining the odd slices of the Julibrot, where features in their natural form are often stretched and twisted beyond recognition. This natural stretching is an inevitable part of the odd slices. It exists for mathematical reasons, one of which is that objects appear far larger in the Julia aspect than in the Mandelbrot aspect, and the odd slices include parts of both aspects. I will have more to say about this stretching in a future FOTD. Right now, it's time to reveal that, with a render time of 4 minutes, the image is barely worth the effort of rendering it from the parameter file. Those who choose not to render may find the pre-rendered image ready for download on Paul's site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Saturday was sunny but chilly, with a temperature barely above freezing. The snow still on the ground kept the dynamic ones safely indoors by their radiators. But I could not avoid a trip outdoors to do some things that needed to be done. This morning is sunny and chilly again. I expect a similar day. Until the next FOTD appears in 24 hours, take care, and see you then.

FOTD 07-12-02 (FMOD Modules [2])
by Jim Muth 07 Dec '02

07 Dec '02

FOTD -- December 07, 2002 (Rating 2) Fractal visionaries and enthusiasts: On some days you just can't find a good fractal. That's what I told myself as I reluctantly designated today's abysmal image as FOTD for Dec. 7. My alibi is that, though I had expected a slow day on Friday, a pile of unexpected work arrived, and after snow- removal duty, I was left with basically zero time to devote to fractals. But even a much-below-average image is better than no image at all. Today's image is a zoom into the 'New View' image of Dec. 4. To add a bit of life to an otherwise lifeless scene, I colored the image with the inside areas set to < fmod >. I named the resulting mess "FMOD Modules". The result vaguely resembles a surreal landscape, with stretched and tortured shapes hanging in the sky above the straight horizon. In the foreground, an eroded, brilliantly yellow peak juts upward from nowhere, while in the distance, mysterious features lurk. The preceding paragraph is an exercise in saying something about nothing. Speaking of the fourth dimension can also be considered saying something about nothing. But at least the fourth dimension is a real abstraction, in the sense that we know exactly how it would appear if it did exist and we had the eyes to see it. And who knows? These days, when physicists speak of 10, 11, or 26 dimensions as though they actually exist, who knows what else might exist. Perhaps, hidden in some undiscovered and undiscov- erable parallel world, a hypercubic crystal of four-dimensional salt actually exists. At least it's worth thinking about for a few seconds. With its abysmal rating of 2 and its render time of 14 minutes, the image is unlikely to be worth the effort of running the parameter file. A download of the completed image is strongly recommended. The download can be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Friday was a partly cloudy, breezy and cold day here at F.C. The snow cover and temperature that never got above freezing kept the intrepid duo snug indoors all day. I was kept quite busy removing snow and by an unexpected job that came in around noon and had to be finished by today. But all went well, and things are back on track. Hopefully, the next FOTD, which will appear in 24 hours, will have a bit more class. Until then, take care, and better things are to come.

FOTD 06-12-02 (Passion Flower [5])
by Jim Muth 06 Dec '02

06 Dec '02

FOTD -- December 06, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's image catches one of those Mandelbrot midgets at an angle where it is most distorted. The actual midget can be seen by checking the M-set at the coordinates of (p4) of today's image. At the angle of today's slice, little is left of the hole, which once was the midget and now lies invisibly at the center of the image, or even of the basin itself, for that matter. At this angle, the basin appears to have split into two branches, though actually it is the angle of the slice that creates the split, cutting the single curved basin in two places. The surrounding areas of chaos, which somewhat resemble comets, are far better defined in the M-set. I named the picture "Passion Flower". At one time I thought I saw a flower blossom somewhere in the scene, though the bloom is now far less apparent. I rated the image at an average 5, which is all I could do for it. (The corresponding midget, which appears in the M-set, would rate a 6 or 7.) With a 3-1/2 minute render time, the parameter file is one way of viewing the scene. A more efficient way is to download the completed GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Today's image is a slice of the four-dimensional Julibrot. The Julibrot cannot be accurately considered an object, because objects are things that exist objectively in the objective world, and to our specialized senses at least, the objective world is three dimensional. I have spent many years trying to visualize a four-dimensional hyper-object, knowing all the while that my effort was futile. The greatest problem is that the surface boundary of a 4-D figure must be three-dimensional, and my imagination invariably produces flat two-dimensional bounding surfaces for all my mental figures. A 4-D hyper-object must have on its bounding outer surface as many dimensions as there are altogether in our space. On the 3-D surface of a 4-D planet, there would be six cardinal directions. Three parameters would be needed to fix a location, and two parameters would be necessary to define a direction. The horizon would not be a circle, but a sphere that totally surrounds and encloses a visitor from the third dimension, as the heavens surround the planet Earth. On such a world, the sunrise would first appear as a brightening concentrated in a particular area. Then a brilliant star-like dot would suddenly pop into existence at the brightest point, grow to the familiar blinding disk, then shrink again to a dot and vanish. At sunset the same thing would occur at another point of the field of view. At night, assuming perfect clarity of the atmosphere, the stars would appear as twinkling fireflies as they rose above and sank beneath the horizon, passing through the 3-D visitor's field of view. The view on a 4-D world would be interesting indeed -- provided, that is, that the visitor could find a way to shield his retinas from light from the side, and also a way to avoid crumpling into a wrinkled heap as a 2-D sheet of plastic wrap does in our 3-D world. It snowed at a moderate rate all day Thursday here at F.C., piling up 8in 20cm by the time it ended at 11pm. Combined with a temperature of 27F -3C, the conditions proved far too harsh for the intrepid duo, who passed the day alternating between the window and the radiator. All things considered, their moods were surprisingly cheery. Unable to get out yesterday, I passed the day getting ahead in the work. As a result, after clearing the sidewalk, I will have extra time this afternoon to devote to fractal hunting. Hope- fully, I'll find something worthwhile. Check back tomorrow to see whether I actually find it. Until then, take care, and fractals can and do make life interesting.

FOTD 05-12-02 (The Laugh [4])
by Jim Muth 05 Dec '02

05 Dec '02

FOTD -- December 05, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's image resembles a disembodied grin -- a rictus someone who likes to use fancy words might call it. I simply call it "The Laugh", a name which properly describes the effect the picture creates. Turned upside-down, the image might be called "The Cry", but let's keep things as pleasant as possible. I'll try to be as pleasant as possible about the image, for which I make no excuses and which I can rate no higher than a somewhat inflated 4. But even a 4-rated image is worth the effort when the time required to render it is only 44 seconds. The hole at the center, shaped like a gaping grin, is actually an odd slice of a midget located near the tip of the northern- most filament of the M-set. At the hole's upper shoreline a bit of one of those ubiquitous straight bridges appears. (In the M-set a slice of this bridge appears as a valley that forms a lip of a bud.) The grin is actually part of a four-dimensional hyper-object. In a space of four dimensions, things that seem absurd in three dimensions become everyday facts. Consider rotation. In a space of zero or one dimension, rotation is impossible. In two- dimensional space, rotation takes place around an axis-point, while in three-dimensional space, rotation takes place around an axis-line. The general rule is that in n-dimensional space, a simple rotation takes place around an n-minus-2 axis. But a simple rotation requires only two dimensions. The remain- ing dimensions simply remain fixed while turning in place. In four-dimensional space, this leaves the two-dimensional axis of rotation motionless, its points rotating on themselves. But even while serving as an axis of rotation, this plane may itself rotate. The resulting motion, which is impossible in three dimensions, is known as a double rotation. When subject to a double rotation, every point of a four-dimensional hyper-object except the point where the two axis-planes intersect is in motion. If the two rotations are equal, all points move in a circle. If the rotations are not equal, the points trace out a surface of double revolution, which is shaped like a four-dimen- sional doughnut. This double-rotation motion can perhaps be more fully realized by considering the Mandelbrot set and Julibrot. With the M-set on the screen, which of the Z dimensions is perpendicular to it, real(z) or imag(z)? Of course, they both are. In fact, every line in the Z, or Julia, plane is perpendicular to the M-set. Keeping the M-set undisturbed on the screen, the Julibrot can be rotated around the M-set, so that every line of the Z plane in turn lies in our 3-space and at a right angle to the M-set. Looking at only the screen, one would never know that the Julibrot was rotating. Now, with the Julibrot still rotating, if the M-set on the screen were to begin rotating on the screen around its origin, carrying the rest of the Julibrot with it, the Julibrot would be in a state of double rotation. Do not try to mentally trace out the path the points would take, it is impossible. It is far easier to imagine the fun of rendering today's super- fast image from the attached parameter file. And those not particularly fond of rendering can download the completed image from one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> I'll have much more popularized 4-D curiosities in the weeks to come. Wednesday was hazy and cold here at Fractal Central, but the day was made interesting by a late morning apparition of two brilliantly colored sun dogs. The temperature of 26F -3C was far too chilly for the ears of the intrepid duo, who also dislike dogs of any variety. They wisely decided to pass the day stretched by the warmest radiator they could find. Gazing from the F.C. window this morning, I see snow falling at a moderate rate with 6in 15cm already on the ground and the snow expected to continue until evening. The fractal cats will need comforting. Regardless of the weather, the human's work still needs to be done however. And the best way to finish work is to start it. So until tomorrow, take care, and be of good cheer.

Xfractint, colormap editing
by Natalie 04 Dec '02

04 Dec '02

Hello again, I tried another fractal generating program for Linux, Gnofract4D. It can't compete with Xfractint, although it has some nice features. It has an evolver-mode (9 images), zooms in and out, there are 9 fractal types, some extra parameter functions, but the nicest feature is: the changing of colormaps (it uses Fractint colormaps!), the fractal is not regenerated (as in Xfractint), the colors are changed instantaneously (like in DOS Fractint). It is possible to edit colormaps in The GIMP and use them in Xfractint. The GIMP also has a gradient editor, which has even more editing features, but gradients have to be changed to palettes to be able to use them in Xfractint. The editing is still very tedious, you can't see directly how the colors turn out in the fractal image, Xfractint has to regenerate the fractal and if the result is not what you want, you have to go back to The GIMP and edit the map again. If the fractal takes a long time to generate, it might be days before you've obtained the result you want. Another possibility is to change the colors of the image in The GIMP, but all Xfractint info will be lost. This is not a problem if you just want to have a nice image, it will be a problem when you want to zoom in or manipulate the fractal with the edited colormap in any other way in Xfractint. So... Dear, admirable programmers, would it be possible to add a colormap editor to Xfractint? Please?? >From The GIMP help file: The GIMP is an OSS (Open Source Software) program covered by the GPL License, which gives you the freedom to access and also to change the source code that makes up the program. >From Gnofract4D help file: Gnofract4D is distributed under the Gnu General Public License. Thanks Natalie PS The GIMP is also great for - adding effects to images - making animations with lots of extra features - adding layers, for example a layer with a copyright notice N. -- Stolen tagline: Linux is like a wigwam, no windows, no gates, apache inside.

FOTD 04-12-02 (New View of the M-Set [3])
by Jim Muth 04 Dec '02

04 Dec '02

FOTD -- December 04, 2002 (Rating 3) Fractal visionaries and enthusiasts: When is Seahorse Valley not a valley?...When it's a bridge, of course. Today's image shows a new view of the Mandelbrot set. But when seen from this angle, it is not the M-set. It's an odd slice of the Julibrot, a slice in some unimaginable direction oriented roughly halfway between the Mandelbrot and Julia directions. To picture the orientation of today's view, imagine the M-set on the computer screen, with normally unseen attached parts of the Julibrot extending invisibly in front of and behind the screen. Then imagine the top half of this invisible 3-D part of the Julibrot cut off and the newly-exposed 2-D surface rotated 90 degrees around the X-axis until it fills the screen. Today's image illustrates that slice. The image vaguely resembles the M-set, but it is not the M-set. The main bay is represented, as are the primary bud on the negative stem and the next bud beyond. Farther west, there is a slice of the prominent midget at -1.75, which barely skims that midget's main bay. Only hints of the stem itself are visible. The large period-2 buds that lie at the north and south edges of the main bay of the M-set are nowhere to be found. They are now lying invisibly in the space before and behind the screen, in the position where the slice now on the screen was originally located. Along the eastern edge of the large bay on the screen, which is actually East Valley, a few of the 'elephants' that roam there can barely be discerned, grossly distorted at this strange angle. The most surprising thing about the new slice is what has happened to Seahorse Valley at -0.75 and Scepter Valley at -1.25. They are in the image, but they have turned into the narrow straight rods which I have named bridges. I have colored these bridges a brilliant green for emphasis. These straight rods are not artifacts. The Julibrot is filled with them. They are caused by the fact that, regardless of where iterated points start, if they do not escape first, they will eventually settle into the same orbits as points that start at zero. The immediate implication is that, when its total shape in the Julibrot is considered, a Mandelbrot valley does not come to a sharp point, but rather a sharp knife-edge. But even this idea is incomplete. The Julibrot is four-dimen- sional, and there are many other orientations in which the Mandelbrot valleys appear to come to sharp knife-edges. In the four-dimensional world, these knife-edges stack together edge-point to edge-point, not side-by-side, forming sharp two- dimensional cutting surfaces, such as a 4-D man would use to shave his hyperface. Like so much that can exist only in the world of four dimensions, these sharp 2-D surfaces are impos- sible to visualize, and the complete shape of the Mandelbrot valleys will therefore never be imagined. I named the lightning-fast image "New View of the M-set". The rating of a below-average 3 might be a bit pessimistic, but hopefully the render time of only 11 seconds will make viewing it worth the effort. As always, the pre-rendered GIF image is available on the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Tuesday was cold and sunny, with blustery winds and a temperature of only 23F -5C. Needless to say, the fractal duo turned around and came back inside as soon as their noses felt the outside air. They passed the day sleeping by the radiators, thankful that they have such a cozy place to take shelter in. This morning is even colder, but there is little wind. It's a fine day to tackle some work. Until next time, take care, and don't get taken for a ride by a Seahorse Valley in disguise.

FOTD 03-12-02 (Training Oblates [5])
by Jim Muth 03 Dec '02

03 Dec '02

FOTD -- December 03, 2002 (Rating 5) Fractal visionaries and enthusiasts: I am sometimes asked, 'where is the fourth dimension located?' It is not an easy question to answer. The first answer that comes to mind is the intuitive common-sense reply that the fourth dimension does not exist. It cannot exist because our space has only three dimensions, with no room in it for an extra dimension. But science has long since passed beyond the realm of common-sense, and such an answer can no longer be considered the final word. Almost 100 years ago the theory of relativity appeared on the scene, which treats time as a fourth dimension. But taking time as a fourth dimension is not very satisfying. We want an extra spatial dimension, a space in which time would be the fifth dimension. The fact that time is handled differently mathemati- cally is an admission that time is not the new dimension we seek. When studying the world of the very tiny, Physicists sometimes work with what is known as 'Hilbert Space'. This space can have as many dimensions as necessary, but it is more a mathematical abstraction than a physical reality. Hilbert space cannot serve as the extra dimension. In the 1980's the idea of superstrings burst upon the scene. These infinitesimal things are supposed to lead the way to a theory of almost everything. They are assumed to exist in 10 or 11 dimensions, with their vibrations manifesting in our space as the various sub-atomic particles. But the extra dimensions are now so tiny that they lie far beyond the range of observation. And even if a way were found to actually observe the hidden dimensions, we could do nothing more than take a measurement that told us that the dimensions were really there. With our two-dimensional retinas and three-dimensional-trained minds, we could never observe the extra dimensions. Yet four-dimensional objects do exist mathematically. The 4-D Julibrot is really there in math-space, appearing objectively identical to all who study it. With our computers we can slice it in any direction desired and study the slices. We can study the six perpendicular planes and the four perpendicular three- spaces that exist in 4-D space. Yet, despite this ability, we still cannot visualize the fourth dimension nor a 4-D object as simple as a hypercube. The limitation is apparently in our visual apparatus and minds. Living in a universe of perhaps infinite dimensions, we can visually observe only 3 of them. And this limitation assures that regardless of how hard we try, we shall never visualize even one extra spatial dimension. But if the fourth dimension actually did exist, in which direction would it lie? When asked this question, I reply that the way to the fourth dimension is sideways to the insides of solid objects. If a point were to start at the center of a sphere and move perpendi- cularly into the fourth dimension, the point would not move toward any point on the surface of the sphere. It would dis- appear at once from the center of the sphere, and move away from it, remaining at the same distance from all points on the sphere's surface. Of course, to our 3-D-trained minds living in 3-D space, this seems impossible, and in three-space it is impossible, but in four-space it is only one of the many apparently impossible things that can happen. I'll have much more to say about four- dimensional curiosities in the upcoming FOTD's. And before I forget, we do have a fractal. Today's average- rated fractal is a scene in the Oblate direction of the Julibrot created by the formula Z^(-2.5)+Z+C. I have named it "Training Oblates" because of the train of indescribable open areas lined in a straight diagonal line. Once again the straight theme appears in an odd slice. I will explain this curiosity also in a soon-to-appear FOTD. The render time of just under 4 minutes is slightly slow for an average image. Downloading the completed GIF file from the internet at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> will be a bit more convenient. Monday was cloudy and chilly here at F.C. The temperature of 45F 7C was not too extreme, but for some reason the dynamic duo of fractal cats chose to remain indoors by the heat source. Not one to interrupt a good thing, I let them sleep most of the afternoon. Today promises to be sunnier, but also blustery and much colder. It will likely be another indoor day for the intrepid ones. For me it will be another work day, and if I hope to finish, I must begin. Until tomorrow, same time same place, take care, and always look to the fractal side.

FOTD 02-12-02 (Fractal Trinity [5])
by Jim Muth 02 Dec '02

02 Dec '02

FOTD -- December 12, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's image shows an odd slice of a midget that lies in the East Valley area of the prominent midget on the main stem of the M-set. At this angle, the tiny open area at the center of the image cannot be said to be a midget -- Julibrot holes appear as midgets only when they are sliced in the Mandelbrot orientation along a critical plane. The orientation of the entire image is so far removed from both the Julia and Mandelbrot directions that the hole at its center appears as a mere slit. Much of the distortion of the hole is caused by the extreme stretching and skewing that was necessary to remove the inherent distortion from the surrounding pattern. The world of the odd slices of the 4-D Julibrot is unlike the world of the M-sets or the J-sets. In the odd slices, the features twist, turn and stretch in an unpredictable manner, and must be unstretched to make reasonable pictures of them. So the stretching that went into today's image is actually an unstretching -- a stretching in the opposite direction. I named the final result "Fractal Trinity". The brilliant white triangle around the center slit reminds me of a religious symbol that might be used to represent the Divine Trinity. I'm not trying to promote religion, but I have always wondered whether fractals have a far deeper significance than mere candy for the eyes and ears. After all, fractals resemble the quantum world of the very small, in that they both can be properly comprehen- ded only by the math that describes them. And like fractals, the world at the quantum level does not really come into exis- tence until we make a measurement (iterate a formula) and force it to do something that we can comprehend. Despite (or because of) its religious connotations, I could rate today's image no higher than an average 5. These distorted Julibrot slices have a certain feeling of stress about them that does not make for totally enjoyable viewing. The render time of just under 4 minutes is reasonable enough, but a download of the completed image, which may be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> is even more reasonable. The sun was strong on Sunday, but the high winds and tempera- tures barely above freezing (33F 0.5C) kept the dynamic cats indoors all day. Their moods were surprisingly pleasant however as they chased the patches of sunlight streaming through the windows. Since they have never figured out which way the sun- light will move, they were only partly successful in keeping themselves in the warm rays. As for me, I know which way the sun will move, but I'm not sure how the day's work will move, so I'd best take some action to see that it moves in the right direction. I'll return in 24 hours, more or less, still in the third dimension but talking about the fourth. Until then, take care, and follow the sun.

Hello again, Yesterday I wrote about the RDS screen that isn't in the main menu, but does pop up after Ctrl-s. It's the same for Starfield and Ant Automaton, they're not in the main menu, but pressing a/Ctrl-a takes you to the parameter screens. It seems that the (in)visibility of the zoombox depends on the colormap. The zoombox is visible with: chroma defaultw firestrm froth6 & froth616 gamma1 & gamma2 glasses1, glasses2, & glasses5 goodega grid headache landscap paintjet topo The zoombox is invisible with: altern default froth3 & froth 316 green grey lyapunov neon royal Is it possible to make the K (up) and J (down) keys in the save parameter screen act like normal character-typing keys? It is quite annoying not being able to type 'Julia'. As soon as you type Shift-j the cursor moves down. The arrow keys work ok (in all menu screens), so the K and J keys aren't needed for navigation.

FOTD 01-12-02 (Not a Minibrot [5])
by Jim Muth 01 Dec '02

01 Dec '02

FOTD -- December 01, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's FOTD features the first of the odd slices of various Julibrots, a theme that will continue throughout December. The Julibrot being sliced in today's image is the best known of them all -- the figure produced by the formula Z^2+C. This Julibrot figure is the assemblage of all the Julia sets into a single four-dimensional unit. It is also the assemblage of all the perturbed Mandelbrot sets, though in this case, the slices are cut through the Julibrot in the completely perpendicular direction. The minibrots that I am so fascinated with are actually slices of holes which are like gas bubbles in a four-dimensional swiss cheese. Their appearance depends on the point at which and the direction in which the holes are sliced. When sliced in the Julia direction, these holes will appear as various julia sets, their exact appearance depending on the point at which they are sliced. When sliced in the Mandelbrot direction, they will appear as perturbed Mandelbrot sets. They will appear as perfect midgets only when the slice is taken at a critical point of the generating formula, which in the case of the formula Z^2+C is zero. The question immediately arises, if these holes can be sliced in at least two different directions, why can they not be sliced in other directions, and in fact an infinity of directions? And if other slices are possible, what might these slices look like? Today's image answers that question. The object at the center of the image, which rather resembles an artillery shell, is part of the Z^2+C Julibrot. But it is obviously not a Mandelbrot midget, nor is it a Julia set. It is a slice through a 4-D hole, another slice of which appears in the M-set as a midget in the Seahorse Valley area. The slice in today's image is taken in a direction rotated 30 degrees from the Julia orientation. In this direction, the hole appears as nothing in particular. It can be said to be only a hole in a fractal, but the pattern that appears around both the Mandelbrot midget aspect and the corresponding Julia sets is still there, though it is distorted into a blunt triangular shape. The hole itself has two sides that are perfectly straight and parallel, a thing that is never seen in J-sets or M-sets. And a glance at the <tab> screen will show that the image has been both stretched and skewed. This is a hint of very important features of the Julibrot figure, which I will discuss in future messages. After much indecision, I have named today's image "Not a Minibrot". Since it is clearly *not* a Minibrot, the name is justified. The rating of 5 for an artistically routine but mathematically interesting image is also justified. Those curious few who would like to see the undistorted Mandelbrot midget can find it in the M-set at today's real and imaginary p(3) or p(4) coordinates. With a render time of only 2 minutes, the parameter file may be the best gateway to the world of 4-D. But for convenience, Paul and Scott have posted the image to their web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Saturday here at Fractal Central featured sun, clouds, showers and wind, with a temperature of 48F 9C. In the evening the temperature started dropping like a rock, accompanied by a few flurries of snow. The cats took their outdoor time in the late morning, when it was sunny and mild. This morning is starting sunny again, but it is very cold and windy. The cats will have a less satisfying day. Since it takes little but fractals to satisfy me, my day will also be satisfying. And I shall return in 24 hours with another 4-D fractal and more talk. Until then, take care, and walk with a fractal in your pocket.

FOTD 30-11-02 (Alieness [7])
by Jim Muth 01 Dec '02

01 Dec '02

FOTD -- November 30, 2002 (Rating 7) Fractal visionaries and enthusiasts: I have named today's image "Alieness". This name could imply that the image vaguely resembles a female alien, or it could imply that the image has a certain alien feeling about it. Actually, it implies none of the above. I have no idea what a female alien might look like, and all fractals have a certain alien feeling. I invented the name because I liked its sound. The parent fractal of yesterday's fly-trap image is also the parent of today's image. It is the same eastward-flying rocket ship, except that the escape radius has been increased to 100, a change that makes a larger difference in today's image than it would have made in yesterday's. Today's midget, with its deep-blue background, amber arms, and tiny points of light, is located near the tip of a filament extending from a second-order bud near the the center of the western shore line of its parent. The overall impression is more of a seasonal decorative scene than anything alien. The small but brilliant points of colored light could almost be a string of ornamental lights strung on a tree, or in this case, a fractal minibrot. The image is above the long-term FOTD average, which earns it a rating of a solid 7. The render time of 3 minutes is just fast enough to make running the attached parameter file a practical way of viewing the scene. And as always, the completed GIF image is posted on the two FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Mandelbrot midget in today's image is the last midget that I will post until January. This is also the last time I will use the MandelbrotMix4 formula until January. The FOTD's for December will feature fractals that are neither Mandelbrots nor Julias. Instead, the December images will be oddly oriented slices through various four-dimensional Julibrots, with special emphasis on the Z^2+C figure. The discussions will feature much blather about four-dimensional space and the figures therein, a good bit of which might actually be correct. (In fact, it all might be correct.) The Friday weather here at F.C. was cloudy, breezy and cold, with a high temperature of only 38F 3C. The cats, who dislike such conditions, let their displeasure be known by displaying their least pleasant behavioral aspects. A treat of left-over turkey only partly restored their good moods. My good mood will be restored if I can get through today doing as little work as possible. Searching for fractals is play, not work, so the time I spend in 4-D Fractal Land will not count as work. And before you can count to one-million, I'll be back with the first in the December series of four-dimensional fractal images. Until then, take care, and don't get decohered.

xfractint crash & more questions
by Natalie 01 Dec '02

01 Dec '02

Hello again I ran some old FOTD pars in x fractint, one of them - Spooky_Radicals (November 27, 2000) - caused a crash and a core dump. I removed the line ranges=..., ran the par again, no problems. The resulting image isn't half as nice as the DOS version though. RDS conversion isn't in the main menu, but the Ctrl-s keys do give access to the RDS parameter screen. The RDS image is ok, but as soon as you go back to the parameter screen and change something, the new image becomes messy. The only solution (as far as I know) is to reload the image, press Ctrl-s, try other parameter settings and if the image is not what you want, reload it again, and so on. Not really an xfractint question, but closely related: Is there any chance that OrgForm will be ported to Linux? Thanks, Natalie -- Stolen tagline: Linux is like a wigwam, no windows, no gates, apache inside. [ Linux Counter: user 230952 machine: 111180 ]

xfractint (in)visible zoombox
by Natalie 30 Nov '02

30 Nov '02

Hello again, After I discovered that the visibility of the zoombox depended on the colormap used, I tried to find similarities in the maps. I didn't find any. Then I played around with the default (DOS) map. I changed the color values in the final triplets (all 0 0 0) and after some trial and error I got a visible zoombox. The final triplet is now changed to 64 64 64. The trick didn't work with other maps, and I really don't know why it works for the default map, but it'll do until the next patch.

FOTD 29-11-02 (Venus Fly-Trap [7])
by Jim Muth 29 Nov '02

29 Nov '02

FOTD -- November 29, 2002 (Rating 7) Fractal visionaries and enthusiasts: The parent of today's image rather closely resembles a rocket flying east. The rocket is a large one, requiring several outzooms to shrink it enough so that it fits onto the screen. Today's midget is located near the tip of the southern fin of the rocket, in an area on the verge of fractal evaporation. I named the picture "Venus Fly-Trap". I gave it this name when the eight prominent elements surrounding the midget reminded me of the fly-catching leaves of a Venus fly-trap plant that I once kept as a kind of floral 'pet', feeding it assorted insects until it could eat no more. No flies are visible in today's image, though I am certain they are there, hiding in the lush growth of fractal mayhem. The iterated expression behind the image adds 0.7 parts of Z^(1.25) to 0.45 parts of Z^(-1.25), then adds 1/C instead of C. The escape radius has been reduced from the M-Mix4 default of 100 to 40, though I doubt that the reduction makes more than a tiny difference in the resulting fractal. The rating of 7 continues my current spate of above-average FOTD images. But I wonder how long the above-average images will continue, considering that in two days I will begin a month-long special of odd Julibrot slices and 4-D chatter. The 9-minute render time is a bit slow, but the image is worth the time spent. And as always, the pre-rendered image file is, or soon will be, available for download from Paul's site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> With a temperature of 36F 2C, the weather Thursday here at Fractal Central was quite chilly, but ample sun and lighter winds gave the dynamic cats a reasonably comfortable half-hour in the yard. In the evening a treat of left-over turkey made them forget any discomfort they might have experienced. This morning I find myself with a backlog of work, so I guess it's time to get busy. The next FOTD will appear in 24 hours. Until then, take care, and enjoy today's fractal.

Autokey script is tricky but useful if you know how to use it and tweak it. I used it succesfully to make very deep zooms like the last half of the 2 universe viddies posted on my web site. I also use it to convert a large batch of images to a different color palette. I can send you these scripts if you want. JackOfTradez

FOTD 28-11-02 (Vision of the Unknown [4])
by Jim Muth 28 Nov '02

28 Nov '02

FOTD -- November 28, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's image takes us into the unknown. Do I believe in the unknown? Of course I do. It would be folly to claim that we know everything there is to know, just as it would be equally foolish to claim that we have already found every fractal that might possibly exist. But there are different varieties of the unknown, and some are more reputable than others. Our civilization is currently obsessed with the scientific way of discovering truth, a method that depends on rational thought and empirical testing. With a few exceptions, this method does not admit the existence of unknown things beyond the range of the senses and their instrumental extensions unless a math can be found that makes predictions which have a chance of being experimentally verified. In the world of science, if a thing such as the existence of ghosts cannot possibly be disproved, it cannot be taken seriously. This does not mean that it does not exist; it merely means that it is beyond the range of scien- tific investigation. Before science can consider something to be 'the unknown', some rational evidence is needed that the thing exists in the first place. Undiscovered things such as 'dark matter' are said to be 'unknown' because they have not yet been found and there is evidence that they do exist. At the same time, there are those people who rational thinkers consider credulous and gullible, because they are not limited by the need to conform to the doctrine of scientific correctness. These 'free-thinkers' consider those who follow the scientific way to be narrow-minded. They don't need evidence, since they have already decided that what they believe is true. In their world, things beyond the range of the senses are a part of everyday life. The position of the planets at the time of birth indicates a person's potential. When people die, they don't cease to consciously exist, but merely become invisible spirits. Such beliefs bring comfort, but this type of 'the unknown' is scientifically disreputable because there is neither evidence that it might be true nor a logical need for it to exist. I am on the undecided fence in all of this, constantly shifting back and forth, but slowly drifting toward the scientifically disreputable side. I am certainly not on the fence when it comes to fractals however. Today's fractal is of the reputable variety. I have named it "Vision of the Unknown". The name is a bit misleading, for actually the scene is very well known. Despite its puzzling appearance, it is nothing less that our old friend, the one and only "Seahorse Valley", seen from a new angle which I call the Oblate orientation. I introduce it at this time because I will make December the month of the fourth dimension, featuring new and unusual slices of the Z^2+C Julibrot and much discussion of the curiosities that exist in four-dimensional hyperspace. I could rate the image no higher than a 4, since among serious fractalists the scene is already well known. It has only the coloring to set it apart from what has gone before. Perhaps its best feature however is its sizzling render time of 55 seconds from the attached parameter file. The pre-rendered image is available on the W.W.Web at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather was cloudy and blustery here at Fractal Central on Wednesday. With the wind making so much noise, the dynamic cats ventured out of doors for only a few minutes. The chilly temper- ature of 39F 4C helped not a bit. A treat of tuna was necessary to keep the duo in good temperament. Today is starting even colder, but the sun is bright and the wind has died down. In addition, there will be lots of Thanks- giving Day turkey by late this afternoon. All this considered, the fractal cats should have a better day. If I survive the feasting, I'll return in 24 hours with the next FOTD. Until then, take care, and if you eat too much turkey and gain a few pounds, sue the turkey farmers for your weight problem.

FOTD 26-11-02 (Mollusks [6])
by Jim Muth 28 Nov '02

28 Nov '02

FOTD -- November 26, 2002 (Rating 6) Fractal visionaries and enthusiasts: Now that I have found a way to eliminate the nuisance of un- wanted e-mail, I sometimes amuse myself by actually reading the pathetic junk. This morning for example, I found 23 unwanted letters in my e-mailbox. Of these 23, three would make me into a 'bigger' man, two had approved my non-existent mortgage appli- cation, and the remaining 18 offered a way I could earn a lot of money by doing next to nothing. Unfortunately, all of the money-making letters required me to spend money before I could find how to get rich by doing almost nothing. Another problem was that most of the letters failed to disclose the nature of the get-rich-quick business they were promoting. I lost track of how many times I read phrases such as 'unlimited demand' and 'this business'. By the time I had finished reading the junk, I was convinced that I could probably do better raising chinchillas or selling sensuous pizzas. Fractals will never make me rich, but at least, they are honest. The parent fractal of today's image combines portions of Z^(-1.313) and Z^(-13.13). Then, to turn the fractal rightside- out, 1/C has been added instead of the normal C. The result is a large Mandeloid with a scattering of smaller Mandeloids arranged in a broad ring extending to the east and south. One of these smaller Mandeloids appears to consist of two Mandelbrot sets partly merged. Today's image is located in a broad valley where the two sets come together. I studied today's image for several minutes before finding the name "Mollusks". I can give no logical reason for the name other than I felt like using it. And the eight dark red features surrounding the midget actually do vaguely resemble steamed lobster claws. (Is a lobster a mollusk?) I rated the image at a 6, which is a bit above average on my scale of fractal worth. It might have rated a 7, were it not for the 37-minute render time. But as always, the completed GIF image is available on the internet at the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Monday weather here at Fractal Central was of the pleasant variety. Warm sun, light winds, and a temperature of 61F 16C kept the cats active and happy in the yard most of the afternoon. Tippy briefly eyed a nut-gathering squirrel, but decided to do nothing but watch. Thomas just watched Tippy. This morning is cloudy and colder, with a raw north wind. The duo will be much less happy, and a treat will likely be necessary. For me it promises to be a routine day -- do the work, then explore the fractal world. The next FOTD will appear in 24 hours. Until then, take care, and have a fractalish day.

FOTD 27-11-02 (A Real Quickie [6])
by Jim Muth 27 Nov '02

27 Nov '02

FOTD -- November 27, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's fractal image might be the quickest of all time, not in terms of render time, though this is under 3 minutes, but in terms of the time I spent in finding the scene with its midget at the center. Running on fractal instinct alone, and using Fractint's evolver feature for the real(p1) and real(p2) parameters, I found a parent fractal that appeared as though it might be promising. With nothing to guide me but instinct, I chose an apparently non-critical area of chaos in the eastern suburbs of the parent, and, simply to see what might lie there, zoomed in at random. Though no signs of the two-way symmetry that indicates the basin of a midget appeared, I kept zooming. I cannot say what drove me onward, but I kept going. The new images came up very fast. Then, after only a minute and much to my surprise, there it was before me -- the unmistakable signs of a midget. Once I had found the rather unique midget, a few minutes of color cycling produced today's FOTD. I have no idea how I stumbled upon the midget. A quick trip back to the surface of the parent will show how unlikely its existence seems from up there. Intact midgets do not appear in non-critical fractals or non-critical-appearing fractal regions. I guess I was just lucky. The name, "A Real Quickie" refers to the time I spent in finding the midget, not the 2-3/4 minutes required to render the image. The rating of 6 is limited by the small effort that went into the coloring. With so much work before me, I had no time to put more effort into the coloring phase. For the convenience of those who would rather nor run parameter files, the completed GIF image is available on the W.W.W. at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Tuesday was a cloudy, chilly day here in Fractal Land, with a temperature that never topped 45F 7C. The fractal cats responded by being irritable when they found the outdoors not to their liking. But when they saw those chunks of tuna appear in their food dishes, their moods improved notably. My mood will improve notably when I take the work now before me and put it behind me. But that will take some effort, and unless I start I'll never finish. Until tomorrow's FOTD, take care, and anything worth having is worth waiting for -- but not waiting too long.

FOTD 24-11-02 (Gills [7])
by Jim Muth 25 Nov '02

25 Nov '02

FOTD -- November 24, 2002 (Rating 7) Fractal visionaries and enthusiasts: The color flap on the Fractint list appears to be winding down. Not surprisingly, it turned out that we were all saying much the same thing in different words. Like the sound of the tree falling in the forest, the answer to the question of whether color exists before it is observed depends on the meaning given to the word 'color'. Today's emerald-colored image, which is surprisingly three- dimensional, vaguely resembles many things. I could have given it many names, but the name I decided on is "Gills". I rendered this otherwise routine scene with the outside set to < tdis >, which colors the points according to the total distance travelled before escaping. The normal equal-iteration-band rendering of the same scene draws a worthwhile image, but one that is not nearly as striking as today's < tdis > version. The parent fractal was created by adding 3.7 parts of Z^(-6.5) to 4.9 parts of Z^(-1.83). It is a three-lobed thing composed of mostly non-critical features. A small critical area does appear on the eastern end of the figure however, and in this area lies a bud with a curved filament extending from it. Today's image is located out near the tip of the filament, near one of the many nodes that lie on it. Due to its striking emerald coloration, I have, perhaps a bit liberally, rated the image at a 7. The render time of 5 minutes is within reason, which helps justify the rating. Those who want still more justice in the rating may download the completed GIF image from one of the two FOTD web sites. Paul's site can be accessed at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's site can be found at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather was brisk here at Fractal Central on Saturday. The sun shone at intervals between scudding clouds, but the wind roared and the temperature stopped rising at 44F 6.5C. The cats, who could endure only a few minutes of such conditions, complained mildly, then settled by their favorite radiators. Today is starting better, though it's still a bit brisk. Time will tell how the day will turn out. Regardless of how things develop, I'll return in 24 hours with the next in the unending series of FOTD's. Until that eagerly awaited moment, take care, and if fractals are made of numbers, why not superstrings? I kind of like the idea of the universe being made of numbers, but if this is the case, where do the numbers come from? . . . . . . And what about those membranes of M-theory? . . . . . . Perhaps I ask too many questions. . . .

FOTD 25-11-02 (Just Another Midget [5])
by Jim Muth 25 Nov '02

25 Nov '02

FOTD -- November 25, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's fractal, which mixes fractional parts of Z^(101) and Z^(-1.5), is a picture of another midget lying in a valley of its parent. And the parent is another indescribable fractal with a critical area filled with bits and pieces of Mandel- material, where the midgets are found. In response to these undeniable facts, I have named the image "Just Another Midget". I rated it at only an average 5. I know of no reason for the merely average rating. The colors might be a bit too brilliant, but fractals can look good with bright colors. I am simply dis-satisfied in some way. Why do I feel this vague dis-satisfaction with today's image? Nothing is wrong with midgets, (Minibrots, atoms). They are among the most interesting of fractal objects. But though their number is infinite, they comprise only a tiny part of the vast universe of fractals. Could I finally be becoming bored with midgets? A couple years ago I went an entire month without featuring a midget in the FOTD. Perhaps I need another such break. Perhaps I need to return to the preoccupation with four-dimen- sional figures and the curiosities of four-dimensional space that filled the FOTD discussions a couple years ago, when I posted many images of odd slices of the 4-D Julibrot figure. The Seahorse Valley area of the Mandelbrot set is perhaps the richest area of that best-known of all fractals. Its Julia sets are among the finest the M-set has to offer. But in addition to Julia sets, the four-dimensional Seahorse Valley area can be sliced to create Oblate sets, Rectangular sets, Elliptic sets and Parabolic sets. These less-familiar sets illustrate slices through Seahorse Valley in the remaining four mutually-perpendi- cular directions of 4-D space, and they are quite rich in an entirely new way. I think I will make December the month of the fourth dimension. The images will feature odd slices of the Z^2+C Julibrot, and the discussions will tell of the curiosities of 4-D space. Mini- brot lovers need feel no concern. When the new year arrives, the Minibrots will return, though not in the nearly exclusive manner of the past year or so. Today's image, which I have almost forgotten in my hyperspace ramblings, renders in under 10 minutes on my tired old fractal- workhorse P-200 machine. The file of the completed GIF image downloads in only a minute from one of the following two web sites: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Sunday here in the Fractal Central part of the world was near perfect, with full sun, light breezes, and a tempera- ture of 59F 15C. The cats were happy and so was I. No treats were needed. Today is promising to be a repeat, except that I now have a pile of work before me. Actually, it's a virtual pile, since the work is contained on a computer disk. When the work is finished, the fractals will appear, and one of them will be the FOTD for tomorrow. Until that serene moment, take care, and beware of rogue fractals lurking in the shadows.

Text fixed?

OK. My Outlook Express was set to send "Plain Text". In the sub-menu for text settings, "Mime" was set encode text using Base64. I've changed that to "None". Hopefully I'm now cured? Don't know what that single line of gibberish was, that appeared at the foot of my messages. I assumed that it was some artefact of the Fractint server! Apologies all round. John W.

FOTD 23-11-02 (Fiery Terraces [5])
by Jim Muth 23 Nov '02

23 Nov '02

FOTD -- November 23, 3002 (Rating 5) Fractal visionaries and enthusiasts: The fractal adventures today are still taking place in the giant claw, this time on the biting edge of the upper claw, where, a short distance inland, I found a two-way symmetry which told me that a Mandelbrot atom was near. Often, these surface symmetries lead to what I call 'dry lakes', where the symmetry ends in a blank, but in this case, a midget was indeed waiting at the bottom of the pit. It's not an outstanding midget, only an average one, with most of the impact coming from the strong color palette. Instead of coloring the outside with the normal equal-iteration bands, I have colored it with the < tdis > option, which creates the fiery terraces surrounding the midget, and explains the name "Fiery Terraces". I have already described the image as average, and that is the way I rated it. The time from parameter file to finished image is 8 minutes on my aging P200 machine. The time required to download the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> is less than half the render time. The dense fog early Friday lifted by late morning, leading to a cloudy day with occasional sprinkles of rain. The temperature of 49F 9.5C was not enough to make up for the wet grass, leaving the fractal cats with a boring indoor day. A mid-afternoon treat of turkey eased their irritation, but the day was not yet finished. A high wind arose at nightfall, which insured a skittish evening. As for me, I've got a bit of work to do before taking it easy for the rest of the day. I'm departing now, but I'll be back in 24 hours with another (hopefully) awe-inspiring fractal from the great beyond (wherever that is). Until that glorious moment, take care, and what's wrong with the philofractal list?

It is largely determined by the wave length of the light striking the retina of the eye. But the situation is not so simple. The sensation of color can also be produced by a white light that flickers on and off at the proper rate. I have seen strong color by staring at a white sky through the blades of a rotating exhaust fan. And we have all seen those disks with black and white patterns on them that create the impression of color when spun at the proper rate. In these cases, the color most certainly exists only in the mind. Jim M.

I think I figured out what is going on here. John's messages are coming through (to me, anyway) as UU encoded. This is a method of encoding binary files using only letters and numbers so they can be sent via text-based email. I ran it through an old DOS UU decoder and it came through fine. John, is there a setting in your email program that might be doing this? I'm probably the only person having problems because I'm using the Lotus Notes email client, which is absolutely the worst email program in the world. Most likely, all other email programs recognize UU encoded messages and automatically decode them. Nick

When you have a little time, could you switch over to this one and cancel the rsync calls to sundog.triumf.ca. That node will disappear behind a firewall in a week or so. Cheers, Noel

FOTD 22-11-02 (Forever Amber [6])
by Jim Muth 22 Nov '02

22 Nov '02

FOTD -- November 22, 2002 (Rating 6) Fractal visionaries and enthusiasts: I've seen the topic of the nature of color being tossed around on the Fractint list lately. One of the questions being discussed is whether the sensation one person experiences when he observes red is identical to the sensation someone else experiences when he observes the same bundle of wave lengths. When I ponder this question, the topic of artistic painting (and fractals) comes immediately to mind. Different people always have different opinions of the same work of art (or the same fractal). Could this be because they actually experience the colors differently? The sensation that is red to one person might appear as blue to another person, (though he would consider it red), while to a third person, the first person's sensation of red might be totally unknown. Perhaps different people actually experience the same work of visual art in different ways, and what is pleasing to one person is truly disgusting to another. There is an old saying that goes, "beauty is in the eye of the beholder". This might be more true than we realize. And could the same thing also be true of the non-visual arts such as music and literature? Another question also comes to mind, this one also of a philo- sophical nature. Since the sensation of colors we see in the world around us does not appear until the information from without reaches the mind, what do the actual external objects actually look like? We cannot say they look like a black-and- white photograph, since shades of gray are also color sensations that arise in the mind. We can only dismiss the question as a meaningless waste of energy, saying that the actual shades and colors of the outer world is an abstract something that we can never know, and try to be satisfied with the non-answer. It is far more convenient to project the inner sensation of color onto the outer world and consider color to be an objective reality. But I can never forget that by doing this we are merely fooling ourselves. Today's fractal rates a 6, and that's in my opinion. I enjoy the color amber. Someone who does not enjoy amber might experience amber as puce, and rate the image at only a 3. The scene is located once again in the giant claw fractal, this time just beyond the shoreline of the largest bud in the nascent Mandeloid near the hinge of the claw. I have named the image "Forever Amber", not after a naughty novel that appeared about a half-century ago, but because of the intensely amber network of intertwined filaments surrounding the central midget. With a render time of a little under 6 minutes, the parameter file is a bit slow. The more efficient way of viewing the image is to download it from the web site of Paul at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Heavy clouds and occasional light sprinkles of rain kept things too wet for the dynamic cat duo Thursday. The temperature of 45F 7C failed to help things. As a result, the duo became sulky, and needed several treats to restore their spirits. Today is starting foggy and wet, promising to be little better. I have a bit of work to accomplish before I can think of what kind of treat to give the duo. Until tomorrow, take care, and make a fractal an every-day event.

I have always thought so, based on a mechanistic view of the systems involved. The "normal" human eye has three types of cones with peak sensitivities spaced on the visible spectrum to provide "optimal" human color vision. There are two main types of color blindness: dichromat and shifted trichromat. I don't know if there are many truly color blind (grey scale only) people, and most of these are probably related to brain defect/injury or albinism (complete lack of pigment). Dichromats have only two types of cones, so their internal reconstruction of colors is substantially less sensitive. Shifted trichromats have one or more types with peak sensitivities shifted so that two are closer together on the spectrum, and consequently provide less resolution in that part of the spectrum. (The cones are sensitive to bell-curve distributions rather than discrete wavelengths, which is how we perceive colors between and beyond the peaks.) Severity of degradation varies with the amount of frequency shift. I have a mild case of red/green color blindness, which means my low energy sensors are closer together than normal; but I have absolutely no trouble with anything other than the really subtle color test cards. I have done my share of resistor color code reading, have properly balanced photographic color prints, and am able to discern the difference between copper and gold. Since we are, by the nature of our 98+% shared DNA, wired basically identically, one can argue that our optico-neural wiring, and hence function, is basically the same. In mammals, certain functions such as clear stereographic vision and motion detection require sensory stimulation to train (rewire) the neural net in the visual area of the occipital lobe. But I see no reason to doubt that color vision is hard-wired from the start.

But it does not describe the creation of color. It describes how the *frequency* of electromagnetic radiation in the visual range is affected by relativistic effects in atoms. Color itself is a subjective sensation in the mind. It does not exist until the radiation reaches the mind via the eyes, optic nerve, and visual cortex. Jim (always subjective) Muth

FOTD 21-11-02 (FMOD Fun [6])
by Jim Muth 21 Nov '02

21 Nov '02

FOTD -- November 21, 2002 (Rating 6) Fractal visionaries and enthusiasts: An earlier start today will hopefully avoid yesterday's log jam here at F.C. For today's image we return to the claw of yesterday's FOTD and concentrate on the area near the origin. When entered into the M-Mix4 formula, the claw parameters draw a default screen with an obvious though somewhat-distorted Mandeloid just north of center and a nascent Mandeloid tucked in on the lower left border. Today's scene lies in a small area of irregularity on the east shoreline of the main bay of this half-developed Mandeloid. When rendered in the outside=iter mode, today's scene has little to recommend it, and rates no more than a 3, but with the outside set to fmod and the proximity set to 1, an entirely new image appears, and the rating jumps to a 6. The image is also helped by the bit of extra effort that went into the coloring. Smooth gradients do not come easily with only 256 colors to work with. A couple weeks ago, there was an FOTD image named "FMOD Fantasy". Today's image is named simply "FMOD Fun". It's an apt name. Fractals, after all, are fun. They're fun to sit and admire, and even more fun to work with. Today's image is all the more fun because of its relatively short render time. Less than 3 minutes are required for the magic to work that turns the attached parameter file into a finished image. Those who don't believe in magic can see the image by downloading it from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> And if fractals are not magic, I would like to know what is. With lots of sun, light breezes, and a temperature of 59F 15C, the weather was ideal for cats and man here at Fractal Central on Wednesday. Needless to say, the cats were happy. The man was busy.

FOTD 20-11-02 (The Giant Claw [5])
by Jim Muth 20 Nov '02

20 Nov '02

FOTD -- November 20, 2002 (Rating 5) Fractal visionaries and enthusiasts: It's another busy day here at F.C., and I'm running late, so the discussion will once again have to be short. In the FOTD discussions, I often describe the parent fractal in which the day's image exists. But until now I have not used a 'parent' fractal as a fractal of the day. But that is about to change. Today's image shows the lobster-claw fractal that is the parent of the "Hyperhot" FOTD of November 18. The resemblance to a disembodied claw is obvious, as is the reason for the name "The Giant Claw". The name could even serve as the title of a grade-B sci-fi thriller movie, if it has not already done so, that is. The claw holds tons of midgets in both arms, and there is also a tiny Mandeloid near the origin. I will be returning to this claw for FOTD images several times in the days to come. The overall rating of a 5 is average. The render time of two minutes should be incentive enough to run the attached parameter file. An alternate way of viewing the giant claw is to download it from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> And don't get pinched in the process. With a temperature of 56F 13C and morning sun, Tuesday was a pleasant day overall, but a brief shower in the middle of the cats' outside romp rather spoiled their day. No problem however. A treat of tuna restored their spirits, and they ended the day purring. Today is once again starting sunny. This time it appears no rain will mar the afternoon, so I expect a good cat day. If I hope to have a good day however, I must first finish the work. Until next time, take care, and don't drown in information.

I'm sure you know what I meant. The actual sensation of color is a subjective phemomenon originating in and perceived by the mind. The nature of that color sensation is determined by the wave length of the light waves striking the retina. Light waves carry attributes such as wave length and polarization. They do not carry color along with them. (I could go into retinal cones and rods, and how they respond to different light waves, but I would rather stick to fractals.) Finally, I have been working with color for 30 years. If I have been wrong about its subjective nature all this time, please enlighten me. Jim M.

FOTD 19-11-02 (Dunes [5])
by Jim Muth 19 Nov '02

19 Nov '02

FOTD -- November 19, 2002 (Rating 4) Fractal visionaries and enthusiasts: An unexpected rush job has arrived, the customer has already called once, and is waiting impatiently, so I'll have to make today's discussion a short one. I found today's scene near a larger midget in the Z^(sqrt(2))+C Mandeloid, located 23.78 levels up the logarithmic spiral. The image vaguely resembles a sea of sand dunes with a mis-shapen midget at the center, perhaps located on the well-known fictional planet known as "Dune". I gave the picture the simplest name possible -- "Dunes". Being found and colored almost automatically, I could not rate the image above average, so I gave it the highest possible below- average rating -- a 4. The render time of almost 19 minutes is slow for such a mediocre image. The best way to see the scene is to download it from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The pleasant autumn weather gave the fractal cats a pleasant afternoon Monday. The temperature of 46F 8C was chilly, but the duo managed to find enough sun to keep them comfortable despite a moderate breeze. I'll be comfortable when I finish this work, so until next time, which will arrive in 24 hours, take care, and make no fractal mistakes.

FOTD 17-11-02 (The Bluest Atom [5])
by Jim Muth 19 Nov '02

19 Nov '02

FOTD -- November 17, 2002 (Rating 5) Fractal visionaries and enthusiasts: I have named today's image "The Bluest Atom". One glance at the image will reveal why the atom in the picture is the bluest. The atom is the midget at the center of the frame. Mandelbrot midgets are sometimes called atoms, as well as Minibrots. Actual atoms, the kind that the world is composed of, have no color. They are far too small. An object's color is determined by the wave length of the visible light that it reflects most strongly. But atoms do not reflect light at all. Light waves are far larger than an atom, and pass by it as though it were not there. A deeper question is whether the particles atoms are made of are there at all. One would assume something is there . . . but is it? . . . The parent of today's image appears as a large irregular Mandeloid bay, with a secondary Mandeloid off to the east. The East Valley of this secondary Mandeloid, which is actually on the north shore, is split down the middle by a cleft that is just starting to open. Today's scene is located in a spiral in a weed-choked cove near the shore of this cleft. The image is broken, much of it consisting of featureless black inside areas. I normally try to avoid such broken areas in my fractal searches, but sometimes these areas produce unexpectedly fine fractals. In today's image, the black areas actually add to the overall somber feeling of the scene. I have rated the image at an average 5. Its feeling of sadness holds it down. If the color palette had been cheerier, I might have rated the picture at a 6. The render time of 28 minutes is unreasonably long for such a gloomy image. To avoid impatience, the download from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> is recommended. It rained steadily all day Saturday here at Fractal Central, keeping the dynamic cats confined to the indoors, where they passed the day in a very un-dynamic fashion. The temperature of 47F 8C did not help at all. Luckily for me, I had stocked lots of tuna and turkey, which kept their bad moods under control. Today is starting just as rainy as yesterday, so I'll likely have to repeat the treats. As for myself, I'm bored with watching rain, yard work is impossible and driving is miserable. After I get a head start on this week's design work, I'll probably reduce myself to watching a game or two on TV and trying to keep the cats happy. The best part of the day will come later, when I shift into my fractal-hunting mode and bring one back alive. Until next time, which will arrive in 24 hours, take care, and are fractals alive or dead? Secondary question: can something that has never been alive be considered dead?

FOTD 18-11-02 (Hyperhot [5])
by Jim Muth 18 Nov '02

18 Nov '02

FOTD -- November 18, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's image bears the name "Hyperhot". The name is whimsical, since nothing in the image gives the impression of heat. The image, with its disconnected features that appear to be multiplying, actually resembles some sort of bacterial growth, but a name such as "Festering" would not attract many viewers, so I settled on the present name. The parent fractal, which was created by subtracting 0.93 parts of Z^(1.8) from 0.18 parts of Z^(-1.5), is shaped quite like a gigantic lobster claw, so large that two outzooms are required to fit it on the screen. Today's scene is located in the smaller arm of the big claw. I could rate the image no higher than a 5. But the giant claw parent fractal holds many other interesting scenes, some of which will appear in FOTD's soon to come, and will certainly have a higher rating. The render time of almost 1/2 hour on my machine is admittedly excessive for an image that brings little new, and can be avoided as always by downloading the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> On and off rain, and a temperature of 41F 5C marred the cats' day Sunday, but ample treats of tuna and turkey kept their dispositions within the bearable range. This morning, we actually have a bit of sun, and a fresh breeze also. If it stays this way, the dynamic ones should have a pleasant afternoon. My afternoon will be pleasant when most of the work is behind me. I finished a good chunk of it yesterday, so my task should not be too difficult. Then it's on to the fractals. Until fractal Tuesday, (every day is a fractal day), take care, and keep seeking for the deeper mysteries.

Here are the config.sys and autoexec.bat files I use with my dedicated Fractint machine. I have also included the directory of all files on the DOS-6.22 boot disk, which on start-up takes the machine directly into the Fractint program, with 634,144 bytes of conventional memory free.

FOTD 16-11-02 (Curly Slices [4])
by Jim Muth 16 Nov '02

16 Nov '02

FOTD -- November 16, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's image is a scene in the fractal that results when 8 parts of Z^(-11) are added to 12 negative parts of Z^(-1.1) before adding 1/C. Normally, this parent fractal would be an island surrounded by an infinite ocean, but by adding 1/C instead of C the entire fractal has been turned inside out, or inverted, and instead of appearing as an island, the fractal resembles a marshy area with X-axis symmetry, which is filled with debris-choked ponds. Perhaps the most prominent feature of this parent fractal is the large fan-shaped feature just east of the origin. Similar fan- shaped features often appear in inverted fractals created with negative powers of Z. At first glance, these fractal fans appear to be totally non-critical and therefore devoid of midgets, but a careful search sometimes proves otherwise. Today's image lies in the outskirts of a larger midget in a cut-off feature in the northern part of its parent's fan. I gave it the name "Curly Slices" when I noticed the resemblance of the four prominent features surrounding the midget to slices of bread with curly extensions attached to their top corners. Maybe it is just my less-than-cheery mood, but I could find nothing in the image that would rate higher than the slightly- below-average rating of 4 that I gave it. The 13-minute render time can be avoided by downloading the completed GIF image from one of the FOTD web sites, which may be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Friday weather here at Fractal Central was very pleasant, and the cats were very happy. Warm sun, light breezes, and a temperature of 63F 17C gave them a comfortable afternoon in the yard. But this morning is cold and rainy, and it will likely stay this way all day, and the dynamic, sun-loving cats will likely be far less satisfied. For me it will be a day to finish a small amount of work and watch the rain. When I tire of watching the rain, I will turn to the world of fractals. The best fractal I find will appear as tomorrow's FOTD. Until then, take care, and turn to fractals when reason fails.

FOTD 15-11-02 (Parabrot [7])
by Jim Muth 15 Nov '02

15 Nov '02

FOTD -- November 15, 2002 (Rating 7) Fractal visionaries and enthusiasts: I have named today's image "Parabrot" because in my opinion it lies just a little beyond the normal fractal scene. (Whether my opinion agrees with the opinions of others is another story.) The parent was found by the Fractint evolver feature, which IMO is one of the program's best features. The parent was created by combining portions of two different negative powers of Z, in this case, Z^(-1.6) and Z^(-3.6), then adding (1/C). This parent is an indescribable thing consisting of many bays filled with islands, with a large irregular ring extending to the east and north. Today's scene is located in a spiral at the southern origin of this ring, near the point where the ring vanishes into the center of a Mandeloid valley. The image itself is one of unusual smoothness, though this smoothness cannot be fully displayed with a palette of only 256 colors. The color bands are not arranged consecutively. The iteration count alternates back and forth in a curious manner, which might be natural or might be an artifact of the math routine. The rating of a 7 could be a bit overblown, but the image is at least a little above average. The render time of a little less than 15 minutes can be avoided by downloading the finished image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday turned out to be very pleasant, with lots of sun and a temperature of 61F 16C. Accordingly, the cats were so pleased that they finished the day with a purr. And I finished the article in "Skeptical Inquirer" magazine. I found it to be rather routine, containing little new debunking material. Basically, it re-stated the obvious fact that before the existence of PSI can be assumed from experimental results, all the other things that might possibly have caused the small discrepancy from chance should be eliminated. Since it is impossible to totally eliminate all the other things that could possibly influence the outcome of such PSI experiments, the world-view of the 'hard skeptics' is still safe, and they will not need to admit the possibility of the existence of the paranormal. As for me, I am now forced to admit the existence of the work on the shelf, which must shortly be finished. It's time to get busy, so until next FOTD, take care, and be cautious with feral fractals.

FOTD 14-11-02 (Four Corners [7])
by Jim Muth 14 Nov '02

14 Nov '02

FOTD -- November 14, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today's fractal is unusual in that it contains flat, nearly featureless areas surrounded by areas of total chaos. The flat areas are of more interest, since many hold midgets at their centers. Today's image shows one of these flat areas, with its midget sitting proudly at its center. To emphasize the difference between the chaotic and flat areas, I have given the scene a color palette that highlights the flat areas. The largest flat area, which surrounds the midget at the center, has four well-defined spirals at its corners, thus the name "Four Corners". The other obvious flat areas in the image appear to also have midgets at their centers, but I have not yet checked these. The parent fractal was created by combining some Z^(-2.1) with a lesser amount of Z^(-8.9), and adding (1/C). The exact portions were chosen at random with the program's evolver feature. The parent's shape resembles a clover-leaf, with no immediately apparent critical areas. But sometimes things can be critical where least expected, and today's parent is a fine example of this always-enjoyable phenomenon. A trip back up to the surface of the parent fractal will reveal how unlikely the existence of today's midget would seem to be when seen from the surface. And some other interesting things will be seen on the way, including a tiny, most unlikely bud, in the valley of which today's scene is located. Not wanting to under-rate myself, I rated today's image at an above-average 7. Yes, I realize that if every image is rated at a 6 or 7, then the standard for an average image will increase until the typical image once again rates a perfectly average 5. But that is a consideration for the future. The render time of 24 minutes is slow. The download of the completed GIF image file is fast. The download can be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather here at F.C. on Wednesday was cloudy, breezy and chilly, with light rain in the morning. The wet grass and temperature of 50F 10C kept the fractal cats pretty much house bound, but they accepted their confinement with only a modicum of displeasure. Today is starting sunny, and it is due to be warmer. The cats should have a better day. My day will improve when the work is finished and I have had time to settle down to read the latest issue of "Skeptical Inquirer" magazine, which I picked up last evening. In it I see an article which, at first glance, appears to state that psychokinesis (mind-over-matter) has been con- firmed by the rational scientific method that skeptics place so much faith in. The article then tries to escape the rational conclusion by stating that something must be wrong with the standard scientific method of doing statistics. I haven't read the entire article yet, but if it in fact claims what it appeared to claim when I skimmed it, I'll have much to philosophize and be cynical about in the near future. If the standard statistical method could lead to a wrong conclusion about psychokinesis, how many other currently accepted statisti- cal proofs could also be in error? On the other hand, if psycho- kinesis is true, how many other 'paranormal' things could also be true? Things could be getting interesting. (Or perhaps I got the wrong impression when I skimmed the article.) Until next time and next FOTD, take care, and though skeptics doubt the existence of a non-material world beyond the senses, why do they still fear that it might exist? (One thing for certain is that the non-material world of fractals does exist.)

xfractint questions and quirks
by Natalie 14 Nov '02

14 Nov '02

Hi, I've been playing with xfractint 20.2.04 for about a week. (I've used Fractint since version 8.) Here is a list of some (strange) things I've observed. (I *did* read the doc and the man-page. The BUGS-section in the man-page points to the README file for a list of bugs, the README file only says: You will almost certainly need to edit the directories at the top of the makefile! I downloaded the complete mailing-list archives, searched for anything related to xfractint, but didn't find an answer to these problems. I submitted the boundary trace bug to the Fractint Buglist (twice), but so far I teceived no response.) 1. ---------- passes=b does not work, it freezes up xfractint. Sometimes the 'freeze' occurs at the very start, sometimes it draws about three quarters of the fractal, but until now I haven't been able to finish a fractal in boundary tracing mode. All keypresses are useless, both in the fractal xterm-window and in the input/output xterm-window. The windows can be closed by <Alt-F4> or by using the mouse. I started xfractint again, zoomed in on the default mandel and changed passes to tesseral. No problems there. Saved the parameters. Changed passes to boundary tracing, xfractint froze (as expexted). Since I couldn't save the gif in xfractint, I made a screencapture in the Gimp, and saved the file as a gif. Copied the par to an old DOS-only machine. Restored the par in fractint (Version 2002 Patchlevel 4). Saved the parameters for comparison. Changed passes to boundary tracing, no problems, saved the par and saved the gif. I now have a par-file with three entries: - tesseral_linux - tesseral_dos - boundary_dos two giffiles - b_dos.gif (57622 bytes) - b_x.gif ( 8622 bytes) If anyone wants them I can mail them. 2. ---------- Why is the initial colormap different from the DOS-version? It has blues and greens, and white where the default.map has blue. I use xfractint map=default.map to get the old familiar default colors back. 3. ---------- In the DOS version I always had separate directories for par, frm, ifs, l, and map files. In xfractint I have to dump them all in the same dir or they won't be found. Is there no way to use multiple directories in xfractint? 4. ---------- In DOS I could move to another dir or to another drive, xfractint doesn't seem to know there are subdirs in the default dir. 5. ---------- Is it possible to create an xfractint.rc file (like sstools.ini)? I know I can add options on the command-line, but I don't think the command-line is long enough to hold a complete sstools.ini file. 6. ---------- When I use <Page-Up> to call up a zoombox it is not always visible. I tried <Ctrl-Ins> and <Ctrl-Del> to change the colors, no effect whatsoever. I tried <Ctrl-I> and <Ctrl-D> too, still no change of color. When using the mouse, the zoombox is visible. It makes no difference if I use the left or the right button. Manipulating the zoombox while using the mouse seems impossible. As soon as I release the button, the zoom-in is drawn. 7. ---------- Sound doesn't work always. Sometimes it beeps (through the speakers) when an image is completed, sometimes it stays silent. I tried the music pars. Message: Oops. I couldn't understand the argument hertz=220 Any key to continue. 8. ---------- In the Helpscreens: Backspace to get to the Last Topic dooesn't work. The Helpscreens get scrambled after moving from one link to another and after moving around with the cursor-keys. I captured the screen-output in a textfile and added a short description of what I did and what happened. Ths file is also mailable. (5642 bytes) Anyone? But... despite the bug(ette)s, quirks and oddities, I still DO love it! Thanks! Natalie -- Stolen tagline: Linux is like a wigwam, no windows, no gates, apache inside.

FOTD 13-11-02 (Scattered Fractals [6])
by Jim Muth 13 Nov '02

13 Nov '02

FOTD -- November 13, 2002 (Rating 6) Fractal visionaries and enthusiasts: With its dull, earthy brown shapes floating before a glowing, celestial blue background, today's fractal has a pronounced 3-D effect. It could be a glimpse of heaven as seen from one of the lower regions, presuming that heaven has blue skies, that is. But it is not. It is a fractal created by combining portions of Z^(-1.77) and Z^(-8.8). The ridiculous escape radius of 10^100 signals that the image is an evaporated one consisting entirely of trapped inside points. The picture consists of spirits of dead outside material made visible by a non-flat inside fill, in this case the < bof61 > fill. I believe this fill colors the inside points according to which iteration comes closest to the origin. I have named the image "Scattered Fractals". I gave it this name when I heard the phrase 'scattered showers' on the weather report on the F.C. radio. It is a true name because, as is the case with most all images, an infinity of smaller fractals is scattered throughout the scene. The rating of 6 might be a bit optimistic for an image with so many dark somber colors in the foreground, but the blue in the background speaks of better things beyond, and justifies the slightly above average rating. The render time of 6 minutes is a bit slow, but regardless of the render time, the completed GIF image can be downloaded in a minute or so from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> With the temperature at 50F 10C, the rain fell all day Tuesday here at Fractal Central, and the cats complained all afternoon, running from one door to another, searching futilely for the door that led to a sunny warm day. They never found the sun, and had to settle for treats of tuna and turkey. Today is starting cloudy and brisk. I've got cats to keep happy and work to finish. Until next time, take care, and enjoy your fractals while you have them.

FOTD 05-11-02 (Creepy-Crawlies [5])
by Jim Muth 13 Nov '02

13 Nov '02

FOTD -- November 05, 2002 (Rating 5) Fractal visionaries and enthusiasts: True, it's a few days past Halloween, but today's image has something creepy about it. With its somber dark blue color palette and its eight objects that could be taken as leeches, it might serve as an adequate cover for a paperback horror novel with a title such as "The Leeches that Sucked the World Dry". (Yes, I could be thinking of certain local politicians running for office. It's election day here in Fractal Central country.) Not wanting to name the image after something as unappealing as a dish of leeches, I gave it the more childish name "Creepy- Crawlies". The parent fractal is a grossly bloated Mandeloid rotated 180 degrees and on the verge of turning inside-out. The main period-2 bud, which is on the east side of the large bay has been totally obliterated by the ballooning bay itself. The bay has expanded so far that instead of the period-2 bud being the most prominent, buds with a periodicity around 30 or 40 are most prominent. Today's scene lies in the northern chaos that has accumulated as the whole fractal has expanded. I am sometimes asked how I find these midgets in unfamiliar areas of unfamiliar fractals. I'm not entirely sure how I do it. My attention is often attracted by elements that appear to have two-way symmetry. Then I simply get a feeling that a midget lies deep down at that spot, and when I go look, I am right as often as wrong. The route I took to today's midget can be retraced in reverse by turning off the logmap and outzooming. The trip back out will go faster if the passes is reset to <g> and thumbnail-sized images are calculated. Today's image, which was calculated in the basic default manner, with equal iteration bands on the outside and blank black on the inside, rates a 5. This is an average rating; the image is an average fractal. The 11-minute render time from the parameter file is somewhat excessive, but relief is always at hand at Paul's web site: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or at Scott's site: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> where the finished GIF image will soon be posted. The weather on Monday was uneventful here at Fractal Central. The partly cloudy skies, light winds, and temperature of 54F 12C made for a pleasant enough afternoon as the dynamic ones checked and explored the yard, finding nothing out of the ordinary in the process. It's now Tuesday morning and sun is once again illuminating the area. I've got a bit of work to accomplish before I can call it a day, so until tomorrow and the next FOTD, take care, and has anyone considered a fractal chess set?

twin graphics card problem
by Richard 13 Nov '02

13 Nov '02

Hi, I haven't posted much here, but I love the whole fractal thing since I found Fractint 19.1 on a CDROM. I have a problem, which I will detail below. I am running a desktop pc (duh) with a new Pentium 4 1.8ghz, with 2 graphics cards : the main is an NVidia Geforce 4 MX440 64mb, and the other is my aging Ati 3DCharger 2mb. What I would like to know is this : Can I run Fractint in DOS on my ATI Card's monitor at 800x600 fullscreen yet continue to run normal windows operations on my NVidia's monitor? If you need any more info, please ask, but I hope someone can help here. Richard. PS - How do you get the par files in a text format? --- Outgoing mail is certified Virus Free.

FOTD 12-11-02 (Solar Wind [7])
by Jim Muth 12 Nov '02

12 Nov '02

FOTD -- November 12, 2002 (Rating 7) Fractal visionaries and enthusiasts: In yesterday's fractal I colored the outside with the < real > option. In today's image I color the inside with the < epsiloncross > option. This option assigns colors to trapped points if they come within a certain 'proximity' distance of the X or Y axes. As far as I can remember, this is the first time I have used this option in an FOTD image. In today's image, the option creates the dark parabolic shapes in the foreground. The brilliantly colored arms consist of normal outside material. The parent fractal, which is created by combining portions of Z^(-1.85) and Z^(-5.5), was found with Fractint's evolver feature. It consists of an indescribable mass of various shaped bays surrounded by equally indescribable outside material. A ring of non-critical debris lies off the screen in the far distant southeast suburbs, but this ring does not figure in today's image, which is located in a valley at the tip of a filament extending from a bud in a small critical area at the northern end of the main body of bays. After studying today's image a few minutes, I was reminded of the solar corona. The name "Solar Wind" soon followed. The problem of rating the image was to decide between a 6 or a 7. In the end, I decided to flatter myself with a rating of 7. The render time of 11 minutes can be avoided by downloading the completed image from one of the FOTD web sites. Paul's site is at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's site can be found at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday morning brought heavy thunder-storms to F.C., but the rain ended by noon, leading to a warm breezy afternoon that, by 3:30pm, dried the grass just enough for the dynamic duo to have a brief romp in the yard. The temperature of 70F 21C made up for any left-over dampness. This morning is once again starting rainy. It remains to be seen how well the fractal duo will handle the fresh dampness. As for me, I've got some work to handle. And the best way to handle the work is to do it. When the work is behind me, I'll start the search for tomorrow's fractal. Until next FOTD, take care, and bomb the enemy with fractals -- they are a lot less damaging.

FOTD 11-11-02 (Something_Fernny [8])
by Jim Muth 11 Nov '02

11 Nov '02

FOTD -- November 11, 2002 (Rating 8) Fractal visionaries and enthusiasts: State-of-the-art hi-tech is great, but it can also be quite annoying. One of its more annoying aspects is the constant need to 'upgrade'. Hardly a week passes where I fail to receive a file in a format that I cannot use. It is most annoying to try to load a file saved in super-publisher-36.2 format into version 36.1 of the same program and get nothing but an error message. Usually, a call to the customer only makes things worse, when I find that the document contains features that only version 36.2 can produce. Then I am faced with the choice of telling the customer that I cannot handle the document unless he makes changes, which he usually does not want to do, or spending several hundred dollars to 'upgrade' to the latest version of the super-publisher program. It must be a plot of the forces of evil -- most likely an invasion of off-world aliens set on bankrupting us so that we will be unable to resist the coming takeover. But I'm not concerned. We'll probably be better off once we have been taken over. ;-) Today's fractal is certainly not bankrupt. And I believe it is the first time I have colored an image with the outside coloring option set to < real >. This option does nothing but add the real part to the iteration count when a point escapes. But at least in today's case, it makes a surprising image. I named the picture "Something Fernny" when I had the impression of ferns growing on a forest floor. The iterated expression subtracts Z^(1.1) from Z^(-1.2) and adds (1/C). The resulting fractal consists of several large open areas, only one of which is an obvious Mandeloid. This Mandeloid is rotated -90 degrees so that its main bud points south and its East Valley lies on its north side. Today's scene is located in a small area of cut-off debris in the interior of this East Valley. I have rated the image at an 8. I was undecided on a 7 or an 8. Since the image appears somewhat different from my usual fare, and because of its 'illuminated from behind' effect, I finally decided on the rating of 8. The render time of under 2 minutes is surprisingly fast for the scene. The potential viewer may become an actual viewer by running the attached parameter file and enjoying the gradual appearance of the image, or by downloading the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and missing some of the enjoyment. The Sunday weather was quite mild here at F.C., but heavy clouds obscured the afternoon sun, and a few sprinkles of rain dampened the grass enough to make things a bit unpleasant for the fractal duo. Being courageous cats, they endured their displeasure stoically, taking their comfort in the temperature of 71F 22C. Today is starting cloudy again, and to make things worse, it is raining and there is a tornado watch in effect. I have a fresh supply of work that could keep me busy until nightfall if I don't get busy on it. Since I would like to be finished before nightfall, I had best get started. As for the cats, they will have to shift for themselves. Until next FOTD in 24 hours, take iterative care, and keep iterating.

FOTD 10-11-02 (The Jaggies [5])
by Jim Muth 10 Nov '02

10 Nov '02

FOTD -- November 10, 2002 (Rating 5) Fractal visionaries and enthusiasts: Take one negative portion of Z^(-8.5), add to it eight negative portions of Z^(-1.5), then add (1/C), iterate one-thousand times and display a critical plane. What do you get? You get the parent fractal of today's image. This parent is beyond verbal description. It is filled with a larger variety of fractal features than a fractal cat has tricks. Basically, this fractal is a large multi-lobed Mandeloid surrounded by scattered smaller disconnected Mandeloids. Today's image is located near the tip of a filament extending from a bud of the northernmost bay of the main Mandeloid. The filament itself has a curiously jagged nature. This jaggedness is reflected in the filaments surrounding the midget in today's image. The whole image appears to have a case of the jaggies, which inspired (if it can be called inspiration) the name "The Jaggies". There is also a vaguely sinister and threatening aura about the image, which creates a feeling of unease suitable for the design of a cover for a paperback horror novel. The image is of average quality; I rated it at a 5. The render time of 6 minutes is a bit slow for a merely average image. A download of the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> is the better choice. As a brief off-topic comment, I have noticed the nature of sounds being discussed on the Fractint list recently. The question arose of what is the shortest sound duration in which a definite pitch or frequency can be discerned. The question has been tossed around a bit, but to my knowledge no one has yet mentioned the reverberation aspect. A sound must have a duration of at least one cycle (hertz) for the concept of frequency to make sense. But even a sound burst of one cycle will produce reverberations lasting many cycles. It is these reverberations that give the effect of pitch to sounds such as the tapping of a pencil on a desk. The ear tends to ignore these reverberations and notice only the initial impact, but if the tapping is recorded on tape and played backward, the importance of the reverberations to the perceived sound of the tapping is immediately obvious. The closest we can come to a sound without reverberation is an electronically produced and recorded sound heard through an earphone headset, but even here, the ear and headset itself create some echo. A pure one-cycle tone heard without echo appears to be an unreachable ideal. The Saturday weather here at F.C. featured no sharp sound transients, which would have scared the cats, but it did feature lots of sunshine, which pleased them. The temperature of 64F 18C pleased them even more. Since happy cats make for a happy day, it was a better-than-average day. Today is starting with less sun, but it is still warm. How the cats will take these conditions remains to be seen. Until next time, which will arrive with little fanfare in 24 hours, take care, and keep the fractal faith.

FOTD 09-11-02 (Intaglio [6])
by Jim Muth 09 Nov '02

09 Nov '02

FOTD -- November 09, 2002 (Rating 6) Fractal visionaries and enthusiasts: With today's much improved image we rise out of the abysmal depths of yesterday's failed attempt to find fractal worth. Today's image rates a 6, which is actually a bit above average. It's not too great a jump, but it's better than nothing. I named the picture "Intaglio". I can give no definite reason for choosing such a name. The word simply came to mind when I studied the image, which actually resembles thinly stretched blueish cloths more than a carved image. The iterated expression that drew the image combines some Z^(-2.5) with about one-tenth as much Z^3, then adds (1/C). The parent fractal is a bloated Mandeloid with its nose to the east, on the verge of exploding and turning inside-out. The numbers catch the parent at a point where its sides have ballooned out to grotesque proportions, leaving the 'main' period-2 bud with its straight stem virtually invisible. Though the stem is small, it is there however, and scattered fractal debris lies beyond its tip. Today's midget lies near a larger midget that lies in this debris, just beyond the tip of the stem of its parent. When rendered with my usual outside=equal-iteration-band method, today's scene has little to note. But in today's image I have set the outside to < tdis >, a method that colors the points according to how far they have travelled before escaping. This, along with some serendipitous coloring, raised the ordinarily humdrum scene from a rating of 5 to one of 6. The render time of today's image on my P200 machine ranges from 1min 7sec with a clean boot to 1min 25sec with all the peripheral drivers loaded. Either way it's a fast render. The download of the completed image is just as fast however, and may be found on the internet at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Friday weather was sunny and mild, with a cat-pleasing temperature of 61F 16C. Accordingly, the cats were pleased. The aging ones spent several hours in the yard, attempting to romp, but actually spending more time sleeping, occasionally waking only long enough to shift position to follow the ever- moving patches of sunlight. I spent the day wrapping up another week's work. Today is starting sunny and even warmer, and for a change I have no work waiting. It should be an interesting day. To see how interesting, check back in 24 hours for the next FOTD. Until then, take care, and keep your fractal side up.

Watcom and Fractint
by Tim Wegner 09 Nov '02

09 Nov '02

Does anyone recall a Watcom version of Fractint? I vaguely recall that this existed once. I'm looking for an old Watcom make file. The watcom compiler is available for free at www.openwatcom.org. If anyone is interested in trying to port Fractint to Watcom let me know. This likely doesn't involve changing (much) code, mostly the make files etc. Tim

FOTD 08-11-02 (Patchwork Minibrot [3])
by Jim Muth 08 Nov '02

08 Nov '02

FOTD -- November 08, 2002 (Rating 3) Fractal visionaries and enthusiasts: Today's below-average effort has the appearance of a patchwork quilt about it. But it is not a quilt; it is a picture of a Minibrot. I could not name it "Patchwork Quilt", so I named it "Patchwork Minibrot". Rather than being seen as a quality fractal image, today's picture is best seen as a sample of what exists in the places that I normally pass over in my fractal explorations. As the image shows, there is a good reason that I put so little effort into these areas. The parent fractal consists of a large double-lobed Mandeloid, with a smaller double-lobed Mandeloid not far to the east, and a more conventional M-set still farther to the east. Today's scene is located in the large eastern valley of the center Mandeloid. The image, with its rating of 3, will bring no cheers from the FOTD viewers. The render time of 52 minutes will lure few but Paul and Scott to run the parameter file. But Paul and Scott will post the image to their web sites when they finish rendering it, where it may be seen with minimum effort. Paul's site is at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's is at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Thursday here at Fractal Central was brisk, bright and breezy. The temperature of 52F 11C chilled the noses of the fractal cats, but they braved the outdoors for over an hour in the afternoon. It's now Friday morning at F.C., and if I can finish the modicum of work that sits on the shelf, I might find myself with nothing to do all week-end but take it easy and search for that lost perfect fractal. Whether I find it or not, I'll return in 24 hours with at least a better fractal. Until that astounding moment arrives, take care, and the quest is the quest.

FOTD 07-11-02 (Spin-Off [7])
by Jim Muth 07 Nov '02

07 Nov '02

FOTD -- November 07, 2002 (Rating 7) Fractal visionaries and enthusiasts: The parent fractal of today's image quite closely resembles a butterfly flying west, complete with body, wings and antennae. Today's scene is located in a bit of debris that lies in a valley that forms a separation between the northern wings. Instead of my normal outside=iter setting, I rendered today's image with the outside set to outside=fmod. The result is a different sort of a midget, which seems to be spinning off fragments of itself. It took only a few minutes to find the name "Spin-Off". This image graphically displays the limitation of the 256-color GIF format. The background should be a smooth gradient, but the GIF format has too few in-between steps for the sharp breaks between bands to blend smoothly. When, if ever, Fractint gains workable true-color ability, this problem will be solved. The image is above average with no qualifiers. It rates a 7. The render time of 5 minutes can be avoided by downloading the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> But if the image is downloaded, the fun of watching it come to life on the screen will be missed. The Wednesday morning sun here at Fractal Central did not last long, as heavy clouds moved in around noon and light showers arrived in the afternoon. The chilly temperature of 50F 10C did not help either. The cats grew sullen as they watched their enjoyable afternoon in the yard vanish with the sunshine. But the 5pm treat of tuna helped cheer them. It's now Thursday morning, and so far, all is well. True, I have the usual amount of work to accomplish, but with a bit of effort, that can be finished by afternoon. Then I'll start searching for tomorrow's FOTD. Until then, take care, and keep searching for the perfect fractal.

FOTD 06-11-02 (Creepy-Crawlies [6])
by Jim Muth 06 Nov '02

06 Nov '02

FOTD -- November 06, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's discussion will have to be brief. I stayed up unusually late last night watching election returns, and overslept this morning. The fractal for today features a midget, (nothing unusual in that), and a continuation of the creepy mood of yesterday's image. I named it "More Creepies". In order to fully appreciate the image, it is best viewed in subdued light. The iterated formula combines a negative portion of Z^(11) with a portion of Z^(-1.2), then adds (1/C). The resulting fractal appears as a Mandeloid with its stem pointing NNW and an extra bay extending SSE beyond East Valley, which is split into two separate valleys. Today's scene is located on the eastern branch of East Valley. Rating the image was a simple task. I rated it at a 6, which is the lowest possible above-average rating. The 12-minute render time can be avoided by downloading the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Tuesday weather here at Fractal Central started sunny enough, but before noon a veil of clouds moved in, which thickened through the afternoon and produced rain by nightfall. The clouds held the afternoon temperature to 50F 10C and held the cats' outdoor time to under an hour. They took their confinement stoically however. This morning (Wednesday) has again started sunny. The cats are enthusiastic, but whether it will remain sunny is yet to be determined. One thing fully determined however is the amount of work on the shelf. In order to finish I'll have to start, so until tomorrow's fractal, take care, and a new world is coming . . . but will it be a fractal world?

Re: clean boot and bat files
by JackOTradez 06 Nov '02

06 Nov '02

Do a "sys a:" command from the Win98SE command prompt (DOS window ok for this) this will create a clean DOS-7 boot floppy with the system files. Then add config.sys and autoexec.bat like these: CONFIG.SYS file: (1 line) break=on AUTOEXEC.BAT file: (4 lines) @echo off path A:\;C:\;C:\windows;C:\windows\command;C:\windows\system;c:\fractint prompt $P$G cls NO TSR's, himem.sys, emm386.exe, etc. I have found thru extensive work that fractint likes clean memory space. Keep it clean. Keep it cool. As for nesting bat files within bat files, use the "call" command; don't just put the name of the bat file in another bat file. You just need to keep track of the logic flow in all the files being called or referenced.

As I wrote in a recent message, I have U.F. on another computer, and I already use it to do deep dives into some FOTD images. In fact, I have several other fractal generating programs on my computers, though I most often use Fractint, (and to a lesser degree, U.F.). Your letter makes a fine commercial promotion for U.F. Are you trying to lure more Fractinters into the U.F. fold? Most on this list are already aware of the capability of U.F., and many already have it on their computers. As for myself, I have found that Fractint best matches my short-burst- of-activity style of fractaling. And let's be realistic. Those who use U.F. are more likely to see fractals as a means of artistic expression, (There is nothing wrong with this -- fractals are indeed a great new means of artistic expression.), while those who use Fractint are more likely to see fractals as abstract mathematical objects made visible. Since I am more interested in the mathematical aspect, though I subscribe to both mailing lists, I find myself more at home using Fractint and discussing fractals on the Fractint list. Jim M.

FOTD 04-11-02 (FMOD Fantasy [8])
by Jim Muth 04 Nov '02

04 Nov '02

FOTD -- November 04, 2002 (Rating 8) Fractal visionaries and enthusiasts: I named today's highly-rated image "FMOD Fantasy". I gave it the name because the scene is an evaporated all-inside one that consists entirely of < fmod > inside fill. Without the fill, the scene would be a total blank. I do not know exactly how the < fmod > fill works. I assume it measures some distance, but however it works, it works quite well with today's screen-full of trapped points. (The < bof61 > fill also produces a fractal rather than a blank screen, though the image produced by the < fmod > fill is by far the better. The parent fractal, which adds Z^(-0.25) to Z^(0.25), can hardly be called a fractal, for it also consists entirely of trapped inside points. With the < fmod > fill applied to it, the parent consists of a large crescent with the horns pointing east, the edges of the crescent lined with buds. Today's scene is located in the valley area of one of the second-order buds. When coloring the image, I used a little more care than usual. It shows in the result. One of the reasons I consider my FOTD images to be mathematical curiosities rather than works of art is that I so often lack the time to find and refine the best color palette for the images. I cannot consider something on which I do less than my best to be a work of art. But as mathematical curiosities, some FOTD images are truly unique. This is not surprising, since fractals themselves are unique. They come from nowhere, exist for a few brief moments, and unless recorded, return to whence they came. Though the appearance of today's image departs from that of my typical images, I rated it at an exceptional 8. The parameter file takes 14 minutes to run on my tired old machine. The GIF file of the completed image takes only a minute to download from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Running the parameter file is more fun; downloading the image is more convenient. The near ideal weather here at Fractal Central on Sunday resulted in reasonably happy cats. They approved of the few patches of sunlight that filtered through the holly trees, and they approved of the light winds. They would have preferred the temperature to have been a few degrees higher than 52F 11C, but they held their complaints to a minimum. Their moods remained adequate well beyond their evening meal time. Today's weather will be similar, though with a few more clouds. The cats' day will likely be similar also. Until tomorrow, when the next glorious FOTD will appear, take care and be mod but not fmod.

FOTD 02-11-02 (Electron Cloud [4])
by Jim Muth 04 Nov '02

04 Nov '02

FOTD -- November 02, 2002 (Rating 4) Fractal visionaries and enthusiasts: Many years ago, when I was just discovering science, I became fascinated with the atomic world. My fascination was caused by a story I read about a man who begins shrinking. I forget the name of the story, (it might be "One Who Shrank"), but in it the man is placed on a block of very dense metal and shrinks until the atoms of the metal appear as large to him as stars and planets. He eventually lands on an inhabited planet, where they tell him that they have seen him coming in the sky for many years. As he continues to shrink, he finds that the atoms of this sub-atomic-sized world are also planets of still smaller worlds, ad infinitum. When I read it, the idea seemed sensible enough, so I promptly went to the local library to read about these miniature inhabited worlds that might exist within the everyday objects around us. But instead of alien civilizations, I found the world of quantum mechanics, where, unless one is a mathematical genius, (which I was not), nothing makes sense. I found that electrons, for example, are not objects in the everyday sense, but clouds of probability, where some indefinable non-thing has a certain chance of existing for an indefinable moment of time. I found that, for electrons, and all atomic particles for that matter, the very concepts of object and location are fuzzy at the best. But my small disappointment was far offset by my fascination with the discovery that the atomic world beneath the physical world is not as I had supposed it might appear to my senses. Today's image could be interpreted as a fractal atom, in which the electron cloud surrounds the nucleus, which in this case is a Mandelbrot midget. In fact, I actually did interpret it this way, and named it "Electron Cloud". The generating expression subtracts some Z^(0.9) from some Z^(-0.9) then adds (1/C). The parent fractal created by this expression is what I call unstable, that is it 'evaporates' when the bailout radius is increased. Since the bailout of today's image has been raised to 10^100, the entire scene has long since evaporated and left behind a totally black screen of trapped 'inside' points. Blank screens can sometimes be saved however, and I salvaged today's blank screen by applying the < bof61 > inside fill to it. The result is not great. Indeed, with its rating of 4, it is a bit below average. But it is worth a look. The slow render time of 1-1/2 hours makes rendering the image from the attached parameter file an option only the most devoted fractalists would choose. Fortunately, Paul and Scott are devoted fractalists, and as soon as they can render the image, it will be available on their web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Friday was chilly and blustery, with a temperature of 54F 12C and heavy clouds that dropped sporadic showers of rain. Needless to say, the duo of dynamic fractal cats disliked the conditions, and showed their displeasure with intermittent shouts of frustration. A treat of tuna eased their distress. My distress, which is not all that great to begin, will be eased even further when I finish the tiny amount of work that still lies before me. The best news of all is that I shall return in 24 hours with the next FOTD, one that will rate at least a 6. Until that moment arrives, take care, and walk with your head in the clouds.

Unfortunately, the ability to find great fractals is like artistic inspiration -- it is not always there when needed. Try as I may, I could find nothing of reasonable worth with the M-Mix4 formula. As a last resort, I turned to the MandelbrotBC1 formula and drew the default Mandeloid created by the very simple formula Z^1.75+C. This parent Mandeloid resembles the classic M-set rotated about 120 degrees cw, with the large period-2 bud sitting peacefully on the northwest shoreline of the main bay. Today's scene is located in the southwest branch of the Seahorse Valley of the parent. It contains nothing that has not been seen before, and has been rated at a very liberal 6. The BC in the formula name stands for 'branch cuts', three of which appear prominently in the image. These discontinuities must always appear in Mandeloids drawn with fractional powers of Z. The BC formula can move the cuts around by changing the real(p2) parameter, but they will always be there. I named the image "Pink and Blue" because of the large amount of pink and blue it contains. I consider the render time of 18 minutes a bit excessive for such a routine image. Patient fractalists will run the parameter file; others, with equal patience but less spare time, will download the finished GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Saturday brought sun and chilly winds here to Fractal Central. The dynamic duo enjoy sun, but the sun was blocked by the evergreen holly trees at the bottom of the yard, which left only the winds and temperature of 50F 10C. The duo does not like chilly winds, and as a result, they were testy all day. It took a treat of tuna followed by a turkey treat to flip them into wash-up mode and restore their good moods. It's now a sunny but chilly Sunday morning. The cats have not yet asked to go out. I have but a tiny bit of work to do before I can get down to the serious business of relaxing and fractaling. The result of the fractaling will appear as tomorrow's FOTD. Until then, take care, and beware of hit-and- run fractals.

There is no exact equivalent for that selection in XP though. I also found an article in PC Magazine that explains how every application can have its own autoexec and config.sys files. I haven't yet found what to put in them to solve the problem, but I'm still playing. In the meantime, I can continue to boot to DOS. I also want to say that I completely agree with your clear statement of the open-source program issues. I'm one of the folks who'd be willing to pay for Fractint. I fully understand and respect Tim's position on this, though. And, as Tim points out, a 13year life-cycle (and still counting!) is an incredible run in any case. Bill

FOTD 01-11-02 (Chromatic Jubilee [6])
by Jim Muth 01 Nov '02

01 Nov '02

FOTD -- November 01, 2002 (Rating 6) Fractal visionaries and enthusiasts: The iterated expression that created today's fractal takes Z^(-2), subtracts Z^(-3) from it, then adds (1/C). This operation creates a fractal which is little more than a hole with scattered debris in it. But a small critical area exists at the east edge of the hole, where a tiny main stem extends east a short distance. Today's image is located on a side branch out near the tip of the stem. The name "Chromatic Jubilee" came to me when I realized that the image works best with one of the Fractint random color palettes. I also noticed that the bands are arranged so that every other iteration is displayed, rather than every consecu- tive iteration. I have no idea why this is so; it likely has something to do with the negative exponents. The rating of 6 seems fair enough. The render time of 4 minutes can be reduced to under 2 minutes by running the parameter file with the passes set to <g>. And finally, the completed GIF is available at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday here at F.C. was cloudy and chilly, but dry, with a temperature of 47F 8C. The cats did manage about 1/2 hour outdoors, but this was not enough to satisfy their desire for adventure, so a treat of tuna was necessary to restore their good spirits. For me, it's the start of another day, maybe a good day, maybe bad. I won't know which until the day ends, when it will be too late to do anything about it. But regardless, I'll return tomorrow with another FOTD and maybe some trivial banter. Until then, take much care, and where is Ned Kelly when we need him?

State of the Fractint program
by Tim Wegner 01 Nov '02

01 Nov '02

Thought I'd clear up a few points. 1. Fractint has always been and will always be open source. This isn't just due to my opinion, it's because everyone who has ever contributed to it has done so with the understanding that it WAS open source. However, as far as my opinion is concerned, I am very happy it is open source, and if I could, I'd change the license over to GPL or a similar license. Easier said than done because we can no longer reach most code contributors. This license change could still happen, but it would be in conjunction with an extensive rewrite. 2. Thanks for all the kind offers of being willing to pay for upgrades. Money is not and never has been an issue. Developers contribute for their own reasons. 3. Right now Jonathan Osuch and occasional other contributers are the only ones maintaining the program. His interest (and my interest) are gravitating to Linux, but we are used to maintaining the Linux version in parallel to the DOS version so we do it. I have never lost interest. It's just that I have a job and a real life and am getting older. I still dream of diving back in. I might, or I might not, we'll see. 4. I don't think the present situation with Fractint is bad or sad. It's the way life is. Software, like people, have a life cycle. I am very pleased that this list is still active and many folks still get pleasure out of Fractint. I suspect Fractint will continue to have a following. It is even possible that it will have a rebirth on other platforms. Whether it fades away or has a rebirth remains to be seen. Either way, I'm happy. Change is the name of the game, especially in technology. Fractint assumed something like it's present form in 1989, which makes it about 13 years old, so in people years that's about a millenium. Not bad!! :-)

FOTD 31-10-02 (Surreal Reflection [?])
by Jim Muth 31 Oct '02

31 Oct '02

FOTD -- October 31, 2002 (Rating ?) Fractal visionaries and enthusiasts: It's Halloween day here at Fractal Central, the day when we pretend that ghosts and ghoulies are real and hope that they are not. In recognition of the day, I have found a fractal so different from my usual unending string of midgets that I can't rate it. The situation is downright spooky. The generating expression combines some Z^(-7.7) with ten times as much Z^(-0.77), then adds (1/C). With an escape radius of one-googol, the resulting image is a blank black screen consisting totally of trapped inside points. Anything that might have once been there has evaporated. But all hope is not yet lost, for the blackness is filled with invisible dynamics that can be made visible with the various inside fills. The <epscr> fill creates an impressive and intricate pattern, but for today's image I chose the <bof60> fill, which tends to draw circles and glowing auras around objects. The result of my efforts is a surreal image in which an indescribable object is suspended over a glassy surface, with the object's distorted reflection visible in the glassy surface. I named the image "Surreal Reflection" as a simple description of the scene. I leave the rating of the image to the viewer. Those who enjoy such pictures will rate it higher than a 5; those who do not will rate it lower. But all will agree that the render time of 54 minutes is excessive. This delay in seeing the image can be avoided by downloading the pre-rendered image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> where the GIF image will soon be posted. The weather Wednesday was totally miserable, with clouds, a steady cold rain, and a chilling wind. Even if it had been dry outside, the temperature of 36F 2C was far too cold for the cats' delicate ears and whiskers. They passed the day indoors, watching raindrops trickle down the windows and asking for food. Today is still cloudy and cold, but at least it's dry. That's a small improvement. The far bigger improvement will come when the work is finished. But before I can finish, I must start, so until tomorrow, when the first FOTD of November will appear, take care, and pause to ponder the impossible.

FOTD 30-10-02 (An In-Depth Look [6])
by Jim Muth 30 Oct '02

30 Oct '02

FOTD -- October 30, 2002 (Rating 6) Fractal visionaries and enthusiasts: Since yesterday's FOTD I have been pondering, (I ponder a lot). I have been pondering the multiple-worlds interpretation of Q.M. If taken literally, this theory implies that there are a near infinity of myselves in a near infinity of alternate universes, living every possible life I might have lived. At the same time, experience shows that I can be in only one place at a time. Can I trust experience? If so, who then are these other versions of myself? And how can they be different versions of myself? If they merely look like me, they are not me, they are my identical twins. Are they unconscious auto- matons? If so, I might be justified in claiming that everyone in this world but myself is an automaton, an unconscious reflection of someone who is conscious only in some remote alternate universe. And when, if ever, does an alternate version of myself stop being me? In a world where I merely blink one extra time, the other version is clearly myself. But what of the worlds where I am born a woman in Mongolia in the year 1347? How can that person be said to be me if I am not aware of her? What of the worlds where I am born a Neanderthal woman? And the worlds where I am born an ape or a bacteria, or a mud-skimmer on a planet in the Virgo cluster? Taken to the extreme, it appears I might end up living through every possible experience every possible conscious living thing could possibly experience. There would even be a world where I am one of the fractal cats, and the cat is me! (But, unless fractals are conscious, there is no world where I am a fractal.) Or is there? Maybe if I properly understood certain esoteric things such as coherence-decoherence and consistent histories, paradoxes such as the above would vanish, or at least become less puzzling. Alas, I am not among the anointed high priests of science, the initiated few to whom these mysteries are revealed by means of arcane mathematics. Today's fractal might not be aware of itself, but I am certainly aware of it. And it is no puzzle at all. The generating expression takes a bit of (1/Z), adds a tiny bit of Z^8 to it, and finally adds (1/C). The resulting fractal is a bulging Mandeloid rotated 180 degrees, with the period-5 buds being the largest. Today's scene is located on a side branch near the tip of the tiny main stem that extends out from the tiny period-2 bud. Most of the worth of the image lies in the fiery coloring. The underlying shapes are nothing spectacular. After an exhaustive study, I decided to rate the picture at a 6. I named it "An In-Depth Look" because of the time expended on the exhaustive study. In most cases, the render time of under one minute will be faster than the download of the completed GIF image file from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The decision is left to the individual fractalist. The weather here at Fractal Central on Tuesday was truly abysmal. A cold steady rain mixed with ice pellets, a temperature of 37F 3C and a biting northeast wind kept the dynamic cats housebound the entire day. Even a tuna treat failed to pull them totally out of their funks. And today is once again starting out abysmally. It will make no difference for my work, but the cats will have another bad day. Until tomorrow and the next FOTD, take care, and take it one fractal at a time.

FOTD 29-10-02 (Feste Fractalis [5])
by Jim Muth 29 Oct '02

29 Oct '02

FOTD -- October 29, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's routine image gives the impression of a gala festival, with brightly colored balloons and streamers hanging everywhere. I named it "Feste Fractalis", which, if it actually is a phrase in some foreign language, is purely accidental. The work of fractal building was accomplished by taking 0.8 parts of Z^(-1.5) and subtracting from it 0.8 parts of Z^(+1.5). Then (1/C) was added. The resulting fractal consists of a large mass of chaos with a skewed Mandeloid near its center, the whole area surrounded by satellite Mandeloids. Today's scene is located in the Seahorse Valley area of one of these smaller figures. The small Mandeloid that holds today's scene appears to be on the verge of vanishing beyond an escape radius, even though other Mandeloids exist farther from the origin. With an unexpected pile of work coming in, I had too little time to search for the best coloring, and had to settle for the pal- ette in the image. I am sure that better coloring is possible for this image, which is why I rated it at a run-of-the-mill 5. The 3-minute render time is acceptable; the download of the completed image is more acceptable. The download will soon be available on the WWW at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Monday was rather foul here at Fractal Central, as heavy clouds, a chilly temperature of 50F 10C, and occasional light rain kept the dynamic cats indoors most all day. As expected, their moods suffered, and a treat of tuna was necessary to restore their good spirits. This morning it's cloudy again, and rain is threatening. It will be another bad day for the duo. For me, it will be a passable day, though not until I finish the things that need to be done. That's it for now. Until next time, take care, and long live fractals.

FOTD 28-10-02 (Moth-Eaten Midget [4])
by Jim Muth 28 Oct '02

28 Oct '02

FOTD -- October 28, 2002 (Rating 4) Fractal visionaries and enthusiasts: In a recent FOTD I speculated about a "Theory of 'Everything'". The next day I received a private e-mail directing me to a web site, where an article about theories of everything is posted. (The article is posted as a graphic image rather than text, so it took a long time to download.) Basically, it is an article about multi-worlds theories. The problem is that the conditions making self-aware life possible in our world are so unlikely that it is almost impossible for them to have arisen by chance. One way out of the dilemma is to theorize a creator or a 'God' who intentionally designed and fine-tuned the world so that life could arise and thrive in it. But this is not really a way out at all, because we immediately ask how the 'God' came to be. Another answer is to posit the existence of a near infinity of equally real worlds. Every world that could possibly exist, act- ually does exist. It is then no surprise that we find ourselves in a world where life is possible. How could it be otherwise? But even here there are problems. Can a world actually be said to exist if it contains no self-aware observers to be aware of it? The realization of the possibility of observer-created reality is nothing new. And if the observation creates the reality, what of the worlds I and most others observe in our dreams, especially our lucid dreams? While we are dreaming, these worlds can be as real and solid to us as the physical world is when we are awake. I doubt that a scientist who wants to be taken seriously would claim that dreams are real adventures in other real worlds. But where is the difference? If we claim that dream worlds are really only brain activity, we must then answer the question of what the physical world processes such as atoms, the universe, and brain activity really are. We need a theory of everything to completely explain anything. In the end, having gone in a circle, we are right back where we started. The final 'theory of everything' would appear to be a long way off. I see that my discussion has wandered rather far from the topic. No harm has been done, however, for today's fractal is sub-par, and I needed a distraction from its deficiency. (On some days, you just can't find a good fractal.) Today's image adds Z^10 to Z, then adds just plain C. The resulting parent fractal is a nondescript circle with 9 bays. Most bays are non-critical, and hold little of interest, but a small critical area does appear on the WNW shoreline. This small area is full of holes however. It is so filled with holes that it actually appears moth-eaten. Today's midget, which lies in a spurious valley where two arms intersect, is equally moth-eaten. And that is the name I gave to it. In an attempt to pump a bit of life into the image, I rendered it with the outside set to < tdis >. This option helps a little, but not much. It raised the rating from 3 to 4. The render time of 17 minutes, even with passes=t, is no help at all. Few will be willing to wait that long to see an inferior image. But most, I hope, will give Paul and Scott a few minutes to render the image, and then go to their FOTD web pages at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and download the completed GIF image from there. The Sunday weather here at Fractal Central was all one could ask for. The sun shone, the sky was blue, and the temperature was 66F 19C. The fractal cats approved heartily by spending several midday hours in the yard, doing nothing much but watching the surrounding activity. At one time, a stray cat appeared in the bushes. The dynamic duo leaped up and were ready for a fight, but the stray wisely moved on. Today, Monday, is starting with clouds and sprinkles of rain. The cats will be complaining about that. And I'll be complain- ing until the work is finished, (but not very loudly). Until tomorrow's FOTD, take care, and perhaps nothing but fractals are real.

Re: Fractint "deadware"? NO!
by Ralph Feltens 28 Oct '02

28 Oct '02

- Lurk mode off - Hello everybody I started my fractal explorations using fractint (version 16.something) when I bought my first PC (around 1990?), and I owe this program (that is, its creators) a lot. Nevertheless, some years ago I switched to Ultrafractal. I know that this is the Fractint list, but it seems a little strange to me that the topics that generate a lot of traffic on this list are the same that also have been appearing on the official fractint wishlist http://web.ukonline.co.uk/members/robin.b2/olig/fracwish.htm page for several years now. These include truecolor support, windows (or at least 32 Bit OS) compatibility and formula compiler enhancements. It is true that UF doesn't have the complete functionality of Fractint (evolver, boundary tracing, L-systems - and yes, the color cycling now implemented in UF doesn't work as smooth as the one in Fractint), but the abovementioned and often asked-for functionalities are realized in UF and work very well, so if someone feels that he or she really needs one of these, she might feel inclined to pay the registration fee for that programm (for those who don't know if the program is worth its money, they can download a fully functional demo version). I am not suggesting to abandon Fractint altogether, but I have the feeling that some people will like the additional functionality offered by UF (and it is quite easy to import Fractint parameter and even gradient files to UF). One possible szenario: find a nice parameter set in Fractint using the evolver, then import the par file into UF and generate the picture in truecolor (I wonder: if the artistic merit of the pictures is not an issue, then why are so many people demanding truecolor support?). And with respect to Jack's email (attached below), as far as I know, every statement he makes does *not* apply to UF 3. Deepzoom: supported now even for user-made formulas (So, Jim Muth, here is your possibility to do deepzoom dives - arbitrary precision math - into your MandelbrotMix formulas). Formula writing: the formula compiler is much more advanced than that of Fractint; additionally, you can also write your own inside/outside colouring formulas (and no limitation to the amount of parameters you can define). Most fractal types: since the whole (orgform?) formula collection can also be used with UF, I think this statement is obsolete. Most options: most definitely not! I don't know what the price for a second hand pentium system is, but I guess it is more expensive than an UF license - and for my part, I wouldn't like to add another PC to my living room just to run Fractint (if I had a spare room for setting up more computers, things might be different - but more probably I would do this only to take advantage of UF's capability to use networked PCs).

FOTD 27-10-02 (Bubbling Lava Pit [6])
by Jim Muth 27 Oct '02

27 Oct '02

FOTD -- October 27, 2002 (Rating 6) Fractal visionaries and enthusiasts: In fantastic adventure games, where intrepid armchair explorers venture into computerized worlds of danger, lava pits are sometimes found. These pits of boiling, bubbling molten rock are just one of the many hazards that block the way to the ultimate goal. If stumbled into, these pits can be fatal to the adventurer . . . that is unless he has in his possession a magic charm of some sort that can enable him to survive things that would ordinarily mean instant death and a trip back to the beginning of the game or level. I mention computer adventure games because today's image reminds me of a lava pit, with bridges of fractal debris spanning the chasm beneath. I promptly named it "Bubbling Lava Pit". No one has yet fallen into the pit, though many have come close. Hopefully, this pit will claim no victims in the future. The formula behind the image is based on the golden ratio, where <a> is to <b> as <a+b> is to <c>. In today's case, I took the negative value and subtracted from it half as much of the negative of its squared value, which simply adds the number one to the original value. The result of this trick is a Mandeloid that resembles two partially coalesced Mandelbrot sets. The East Valley area of this figure is relatively undistorted, and that is where I found today's scene. When searching for a rating, I looked at yesterday's image and compared it with today's. An honest comparison led me to a rating of 6, which is still above average but only slightly. The render time of around 4 minutes is in line with the worth of the finished result. And as always, the finished image is available on the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Heavy rain fell during the pre-dawn hours Saturday here at Fractal Central, but by mid-morning the clouds departed and the temperature soon rose to 66F 19C. By afternoon, the grass was dry, which gave the dynamic duo the chance they needed to catch up on lost outdoor time. The extra time outdoors made them so happy that they almost forgot to ask for food when they returned inside. It's now Sunday morning. We made it through Saturday with no unexpected disasters and a minimum of work. Hopefully, today will be a repeat. Until next time, take care, and then have a little fun.

FOTD 26-10-02 (Super Symmetry [8])
by Jim Muth 26 Oct '02

26 Oct '02

FOTD -- October 26, 2002 (Rating 8) Fractal visionaries and enthusiasts: The theory of supersymmetry is the latest fad in physics. It is supposed to show the way to the ultimate theory of (almost) everything (TOE). Included in the theory are a multitude of new 'sparticles', and mathematical abstractions known as super- strings, with perhaps 7 or more extra dimensions for the super- strings to twist, turn and vibrate in. The intersection of vibrating, multi-dimensional superstrings with our three-dimen- sional space is supposed to appear as the familiar 'particles' of traditional physics. None of this string-business has been directly observed, nor is it ever likely to be. The theory is so popular because the numbers can be made to add up. When I see stuff like this happening, I wonder whether we have really discovered a new part of outer reality, or are merely playing games with numbers and devising clever experiments until, purely by chance, we finally find a test that appears to confirm our expectations. Then I sit back and wonder whether the whole vision of the atomic world is nothing but a model of our own creation, and finally I look metaphysically through the Fractal Central window, out at the universe, and wonder the same. Of course, the TOE is not truly a theory of absolutely every- thing. Unless I have missed it, the theory does not suppose to tell what the superstrings are made of, (If it is energy, what is energy made of?), or why the strings exist in the first place. The theory also ignores the subjective world of thought and awareness. I suppose these inner things are shuffled aside because they are supposed to arise at a level above the quantum world. (Give metaphysicians the problem, then ignore and mock them because there is no way to test their theories.) Yes, I realize that you have been waiting for the connection to fractals, and here it is: I named today's image "Super Symme- try" because the filaments swirling around the central midget match my vision of what a superstring might look like . . . if it had an actual appearance, that is. I rated the image at an 8, because, with its rings of golden filaments on a blue back- ground, it is rather striking, and also because blue and gold are my old high-school colors. The parent fractal has the same nature as the most recent parents, with a central Mandeloid surrounded by a vast, sprawling suburban region of filaments and rings. Today's image is located on a filament inside a ring near the tip of a filament extending from a crooked bud on the east shoreline of the northern bay of the Mandeloid. I rendered the image in the default outside=iter manner. I used the passes=b option because it is very fast and works perfectly with this image. With the images' render time of one minute, finding the fastest rendering method is not very significant, however. But for the convenience of the non-renderers among us, the completed GIF image may be found on the internet at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather continued cloudy and chilly here at F.C. on Friday, but at least the morning was dry, which gave the dynamic duo the opportunity for a romp in the yard. Unfortunately, the temperature of 46F 8C was a bit too chilly for their sensitive ears, and they were back indoors within 20 minutes. In my world, it's once again Saturday morning, and all is well here at the fractal depot. If I'm lucky, I'll get through the day without doing any significant work. If I'm not lucky, anything could happen. So check again tomorrow to see what does happen. Until that stupendous moment, take care, and if a fractal crosses you, cross it right back.

I, for one, would be willing to pay for an upgrade. And marketing Fractint as shareware, or something similar, would add an incentive that might draw new programmers into the development team. But I think Tim is committed to the open-source freeware concept. With a spare computer dedicated to DOS and fractals, I have no problems with the current DOS platform.

Corrupt display on exiting from Fractint
by Barber138＠aol.com 26 Oct '02

26 Oct '02

I am a newcomer here, though I have been using Fractint on and off for some time. I expect this has been answered lots of times before, but here goes. I run Windows 98 SE and after running Fractint, particularly in SF7 display mode, I find that the Windows video display is so corrupt as to be useless. Typically just black and white, no detail, no text, no cursor. The only cure is to re-boot. Grateful for any ideas! Jonathan Barber Birmingham England

>So let's do a "straw pole" to establish who >here is willing to "PAY" for an upgrade to >Fractint? Well, I would be willing to pay for an upgrade, but I don't think that's the main problem. First of all, I think it's more of a problem with time rather than money. Anybody with the skill to rewrite Fractint probably already has a full-time, well-paying programming job. I don't think the job of rewriting Fractint can be done in any reasonable length of time by somebody (or even more than one person) working part-time in the evening. And I don't think anybody is going to quit their full-time job to do it as it is doubtful they would make much money with shareware revenue. Secondly, and more important to me, is that Fractint is open source. I believe in the open source concept, *not* because it allows me to get free software, but because of all the other advantages it has. In fact, it would probably violate the copyright to turn Fractint into shareware. I doubt if Tim would allow it. Nick

FOTD 25-10-02 (A Ringing Spectre [7])
by Jim Muth 25 Oct '02

25 Oct '02

FOTD -- October 25, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today's image continues the same theme as the most recent three images. One negative part of Z^(-14.14) was added to six negative parts of Z^(-1.414) before 1/C was added. The relation to the square root of 2 is intentional. The resulting parent fractal consists of the same large many-lobed Mandeloid as the past three FOTD's, but in this case, the enormous rings to the east are missing. The northern bay of the parent is partly obscured by two thick arms extending toward its mouth, which create the impression that the area is not critical and therefore no midgets will be found there. However, in the worlds created by the M-mix4 formula, things are not always as they first appear, and a closer examination of the eastern arm revealed suspiciously symmetrical areas. When I dove down into one of these areas, I did indeed find a perfect quadratic midget. The entire area is in a state that I call 'eroded', with the normally solid outside elements broken by numerous holes, which in many cases are larger than the midget itself. When the scene is calculated at the default bailout radius of 100, the holes are so numerous that they comprise the greater part of the scene. When this situation exists, the better fractals are often found when the remaining outside material is 'evaporated' by raising the bailout radius to one-googol, leaving only the ghost of the midget that was once there. It is this midget- ghost that is visible in today's image, which totally consists of trapped 'inside' points. The ghost is made manifest by the inside fill of bof61. With its 3-D effect, the ghost-midget rates a conservative 7, perhaps a liberal 8. I decided on the lesser rating; I could just as honestly have chosen the 8. (Is today's image really one whole rating beneath yesterday's?) I have no explanation for the name I gave the image -- "A Ringing Spectre", but the words have a poetic quality that rather matches the feeling of the blue and gold image. The 12-minute render time is somewhat slow, making the download the wiser but not quite as much fun choice. The download may be found at both Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Thursday was most unpleasant here at F.C., with heavy clouds, a raw northeast wind, occasional drizzle, and a temperature of 43F 6C. The dynamic cats were very undynamic as they passed the day in their favorite chairs, stirring only to look outside and eat. Today promises to be a gloomy repeat, so I guess it's a good chance to get ahead on some of the work I've been putting off. Until tomorrow, take care, and we have evaporated milk, why not evaporated fractals?

The problem lies in finding someone able and with the time to do the upgrading job. As an old-time user, I am not bothered by the DOS platform, nor would I resist a Fractint upgrade to a state-of-the-art OS. I enjoy the DOS speed, as well as the full-screen when searching for fractals. I can endure the limitations imposed by DOS, perhaps the greatest of which is the inability to apply arbitrary precision math to type=formula fractals. But if a native XP version of Fractint were released which bypassed this limitation, as well as the video-mode problems, I would likely switch to it. Does anyone volunteer to do the job? Jim M.

FOTD 24-10-02 (Starring a Midget [8])
by Jim Muth 24 Oct '02

24 Oct '02

FOTD -- October 24, 2002 (Rating NA) Fractal visionaries and enthusiasts: With all the breaking news, things are hectic here at F.C. this morning, so today's discussion will be short. To produce today's fractal, I went back to the fractal of two days ago and again raised the value of the exponents of Z, this time to -1.32 and -13.2, and at the same time, reduced the portions by 40 percent. This small change made a large change in the appearance of the parent fractal. Today's parent fractal consists of a single large, multi-lobed Mandeloid, with a large but partial ring originating in a valley at the north end and stretching out east, down and around to the southern part of the parent. Today's scene is located at the end of the main stem of a larger midget located near the point where the ring emerges from the northern valley. I named the scene "Starring a Midget" after the vague star-like yellowish area around the midget. I gave the image no rating. Due to the hectic news developments, I had no chance to study the image in a detached manner. The parameter file requires 14 minutes to run. Those who do not wish to enjoy watching the image develop one line at a time, may download the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Wednesday weather here at Fractal Central was quite pleasant. The temperature of 61F 16C was spoiled only by a few too many clouds in the afternoon. But the cats enjoyed the day nevertheless. It's a very active morning here at F.C., and I have the usual amount of work to do, so I'd best get started on the task. Until tomorrow, take care, and when the going gets tough, the tough use common sense.

Reply to Mark A. Freeze post: Good words ... I think. Actually, the Fractint program is excellent enough as it is and runs - it isn't of any concern what OS it is using. I have just installed XP and am having enuf trouble with it as is I will not even think of trying Fractint on it when it runs so well on DOS 7. There is a "port in progress" supposedly to rewrite Fractint for Windoze NT, which would also then be for XP. I don't know how far along it is or if it is even continuing; they, like so many others in cyberspace, ignore my email.

Dave/Tony, I just wanted to clear up some confusion in case others are trying to solve problems following this discussion. Tony, you had asked me: > What are your default desktop video settings when in Windows XP? You can > determine that by right-clicking your mouse on a blank part of your > standard desktop and then clicking your "settings" tab. Is there a > possibility in XP that you can't exceed the default video settings of your > desktop? i.e. if your default video settings are at 640x480 you can't > access 800x600, also check the settings of your Fractint.exe "Dos box". I replied: My screen resolution in XP is set at 800 x 600 so that can't be it. I looked at the settings of the DOS box. The only setting I can see that directly addresses resolution is on the Compatability tab. There is a box to check off that says "Run in 640 x 480 screen resolution." I have it unchecked. (I've tried it both ways and it doesn't change anything.) The memory settings of the DOS box are set at the defaults. Per Steven Hessler's info posted here last week, these shouldn't matter. My screen colors are set to 32 bit, btw. I'm still playing around with the DOS box settings, but I haven't found any that make a difference. Bill

FOTD 23-10-02 (Silverhouse Fractal [8])
by Jim Muth 23 Oct '02

23 Oct '02

FOTD -- October 23, 2002 (Rating 8) Fractal visionaries and enthusiasts: For today's image I took the -1.23 of the past two FOTD's, changed it to -1.28 and got a similar parent fractal with different details. This new fractal has new valleys that yesterday's lacks, some of the valleys more convoluted, with more fragmented elements. Today's image lies at the tip of a rather unique broken filament extending from a bud in one of the new valleys. The filament is more of a discontinuous chain of rasp-like elements rather than a continuous jagged line, and as always, the nature of the filament is mirrored in the elements surrounding the central midget in the image. I gave the image a rating of 8, which might be a bit above what it is actually worth, but the scene is still an interesting one, well worth the 7 minutes required to render from the parameter file. I named the picture "Silverhouse Fractal". When I named it, I must have had a logical reason. If there was a reason however, it now eludes me; so for all intents, the image can be considered as having been named by accident. The image can be seen without the need for running the parameter file by downloading it from Paul's FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> It was another near-perfect Autumn day here at Fractal Central on Tuesday, with sunny skies, light breezes, and a temperature of 63F 17C. The cats enjoyed the perfection to the utmost, exploring the farthest reaches of the yard and even chasing a nut-gathering squirrel up a tree. In the evening, they were thoroughly tired out, and fell asleep soon after their evening meal. Unfortunately, I'll be unable to fall asleep until I work my way through another day. So I'd best get busy. Until tomorrow, take care, and almost every fractal is a new one.

FOTD 22-10-02 (New World Symphony [6])
by Jim Muth 22 Oct '02

22 Oct '02

FOTD -- October 22, 2002 (Rating 6) Fractal visionaries and enthusiasts: For today's image, I stayed in the same parent fractal that produced the past two FOTD images. The parent fractal consists of a group of weird-shaped Mandeloids, with a jagged filament leading from the eastern-most figure to an immense ring lying farther to the east. Today's image is located in the area where the filament joins the ring. Other disconnected rings lie scattered even farther to the east, but these are not involved in today's image. I may visit these far-out areas in a future FOTD however. The FOTD for today has mixed themes within its single image. The ovaloid elements extending straight out from the center midget create a feeling of rigid inflexibility, while an element of chaos is added by the twisting, jagged filaments in the discontinuities, which cut off parts of some ovaloids. I named today's picture"New World Symphony". There is an actual New World Symphony, which, though it is one of my favorites, has no connection to the image. The name merely expresses a vague feeling of the nature of the scene. I was about to rate the image at a 7, but then I recognized the resemblance to several earlier FOTD's and decided to drop the rating to a 6. This is still above average, but only slightly. The render time of the parameter file is a nominal 8 minutes on my aging fractal computer. That time will be correspondingly shorter on newer, faster machines. The image may be seen by running the parameter file, or by downloading it from one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Monday here at F.C. was rather pleasant for late October. Morning clouds burned off by noon, leading to a sunny mild afternoon with a temperature of 61F 16C. The dynamic cats took full advantage of the mild conditions by lurking several hours in the holly thicket, where the holly berries, which decorate at Christmas and feed the wintering birds, are just beginning to ripen. As for me, I'm just beginning another day's work, and it's time to turn off the fractal mode until the work is finished.

Re: Fractint and Windows XP

Thanks to Tony et al. I have added a second hard drive to my machine. I created a FAT partitiion on it and put Fractint there. I created a Fractint.cfg file by booting to DOS with a Windows 98 boot disk and running makefcfg.exe. Oddly, the video modes in the new Fractint.cfg all work except one, 1600 x 1200. I can live with that though. I can use the disk video modes if I need to create a hi res picture for printing. I still cannot get the program to use any video mode above 640 x 480 when going through Windows XP. I must still boot to DOS to run Fractint to get the rest of the modes in Fractint.cfg to work. It does not matter which boot disk I use for this, by the way, the XP or 98 version.

Why are we still holding on to Fractint?
by David Dollevoet 22 Oct '02

22 Oct '02

For visual scanning a M-set for J-set parameter choices, Fractint's full screen display has clearly been the best alternative for me. Also, Fractint's capability to render to screen at various resolutions has been a tremendous time saver. This has been especially true for iterative J-set selection in multiple parameter models.

FOTD 21-10-02 (An Exoteric Brot [8])
by Jim Muth 21 Oct '02

21 Oct '02

FOTD -- October 21, 2002 (Rating 7) Fractal visionaries and enthusiasts: The fractal part of today's discussion will be short, since I have taken too much time writing the above rant, which appears on the philofractal list. Today's fractal is a picture of a midget that lies in the same parent fractal as yesterday's image, and most of what was true for that image holds true for today's image as well. I named today's image "An Exoteric Brot" because it can be enjoyed even by those uninitiated into the mysteries of higher math. And I rated it a 7 because it's really not too bad. But the render time of 1/2 hour is not too good. Luckily, that wait can be bypassed by downloading the finished GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Sunday here at the old fractal emporium was quite fall-like, even though the leaves are a bit late turning colors this year. Grey skies, chilly breezes, and a temperature of 55F 13C held the cats' outdoor time to under an hour. But their 45-minute romp seemed to be enough for them, since they were quite happy once back indoors and eating their regular meals. It's now Monday morning, and, unlike recent days, I find myself with more than the usual amount of work to be done. I guess the fractals will have to wait until the work is finished. Until tomorrow, take care, and one of these decades I might grow bored with fractals, but it won't be this decade.

My screen resolution in XP is set at 800 x 600 so that can't be it. I looked at the settings of the DOS box. The only setting I can see that directly addresses resolution is on the Compatability tab. There is a box to check off that says "Run in 640 x 480 screen resolution." I have it unchecked. (I've tried it both ways and it doesn't change anything.) The memory settings of the DOS box are set at the defaults. Per Steven Hessler's info posted here last week, these shouldn't matter. Bill Rossi

Re: Why use Fractint, and P4-DOS7
by JackOTradez 20 Oct '02

20 Oct '02

Replying to Tony Parker post: I use Fractint because it is still the most accurate of the rendering progs, and it can zoom far deeper and with higher iteration count, both of which are most important to me. Also, it is easy to create batch files to run Fractint in auto mode and create animations, which is what my programs do. As for your bare-bones Pentium-4 idea, I advise otherwise! I spent much of last year using 3 systems and various operating system/configurations to optimize Fractint. I conclusively found that the Pentium-3 works better than Pentium-4. Presumeably, something to do with the chip/instruction set etc.; Pentium-4 does not like DOS. Use a Pentium-3. Also, run Fractint in native DOS (not a windoze shell), loaded without TSR's, himem or emm386 or windows drivers. Clean DOS works best. I created a separate bootable partition and did a "sys c:" command from a boot floppy to create a clean DOS OS for Fractint, and have been using it for all my animations.

FOTD 20-10-02 (Four Legs [8])
by Jim Muth 20 Oct '02

20 Oct '02

FOTD -- October 20, 2002 (Rating 8) Fractal visionaries and enthusiasts: Curiously, now that I know how to control the inflow of junk e-mail when I don't want it, I actually have fun, when I'm in the mood, reading some of the pathetic stuff. Much of my junk e-mail informs me (presumably by law) that I have opted in to a mailing list to receive absolutely unwanted things such as free passwords to dirty web sites. And I would like to have a dollar for every time I have been relieved of the non-existent debt that I cannot pay. ;-) This flood of e-mail concerns me. I fear I might be developing amnesia, or perhaps even a multiple personality, for I have no memory of opting in to receive anything whatsoever. In fact, I would not know where to go to opt in even if I wanted to. Where are all these opt-in lists found? Wait! I know what happened! The cats did it! Now we can get on to the fractal business. ;-) Yesterday's fractal rated a lowly 4, so today I have doubled my effort and produced a fractal that, despite the somewhat gaudy background, still rates an 8. By doing so, I have atoned for my misdeed of losing the image that was supposed to be the FOTD for October 19. The high rating of today's image comes largely from the coloring, which I spent extra time in doing, and also because, unlike yesterday's image, which looked like just another M-set midget, today's image is unlike anything that, as far as I know, exists in the classic M-set. The parent fractal consists of a large cluster of Mandeloid- shaped bays with some huge fractal rings much farther to the east. Today's image lies in the center of a valley of one of the Mandeloids. The formula behind the image combines negative portions of Z^(-1.23), Z^(-12.3), and (1/C). For some reason, combining powers of Z whose absolute value differs by a factor of 10 seems to result in unusually interesting fractals. Of course, it could also be chance. I have named the image "Four Legs", because the four prominent appendages somewhat resemble barbecued chicken legs. The render time of 26 minutes is a bit too much, so a download of the completed GIF image is recommended. The GIF file may be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Saturday here at the Fractal Eclectic Emporium was cloudy, with a temperature of 61F 16C and just enough rain to keep the grass too wet for its final trimming of the season. That made me happy, but the cats complained loudly that they could not go into the yard without getting their paws wet. They must think that, because I control their food supply, I also control the weather. I stifled their complaints with a treat of tuna. Today is once again starting cloudy, but so far it has not rained. With the breeze drying the grass, the dynamic duo might manage a trip into the yard with dry paws before the day is finished. As for me, I feel lazy. Most likely for the rest of the day, I'll do little but forget the grass and explore for fractals. But I shall return on schedule in 24 or so hours. Until then, take care, and be at one with your fractals.

It could well do so, because the P4 is optimized for 32-bit code, not the 16-bit code Fractint uses. You might check places lke Tom's Hardware Guide or ExtremeTech for tests and reviews on that topic. IIRC, the AMD processors run 16-bit code much faster than the P4s do. >BTW there's a way to edit msdos.sys to boot directly to the DOS 7.0 command >prompt.

Re: [Fractint] Re: Fractint on XP
by Hans-Joachim Metzger 20 Oct '02

After my experiences with Virtual PC 4.3 reported earlier, I've been following Nick's suggestion to try Virtual PC 5.0 which, according to him, is supposed to be faster than the previous version. DOS under or in Virtual PC 5.0 IS in fact significantly faster than in 4.3 - but only where video is not involved (or only involved in text mode). In other words: Unfortunately, the calculation of fractals in Fractint in DOS in Virtual PC 5.0 in Windows XP on a 2 GHz Pentium4 is still SLOWER than, for example, on a 700 MHz Pentium III. (This is "empirical evidence". I don't know why this is so. But there have been hints that the chip instructions and DOS are not really on good terms...) So, for the time being there does not seem to be a reasonable or convenient way to run Fractint under the Windows XP OS software. At least there is a way to exploit the benefits of some fast pieces of hardware. I've tried Tony's idea: Installing Fractint on a (newly created) small FAT 16 partition (2 GB max), booting with a DOS floppy and running makefcfg. Result: Almost everything I was looking and hoping for. It is FAST!. It is considerably faster than on my 700 and 800 MHz Pentium IIIs. And I managed to generate the following video modes including 1600x1200x 256 - in fact this a copy of the fractint.cfg produced with makefcfg (my card being a NVidia GeForce4 MX 460): ; FRACTINT.CFG File ;key name of adapter/mode | AX | BX | CX | DX |mode| x | y |clr| comments ;========================================================================== ======= F2 ,VESA Color Palette Mode ,4f02,130, 0, 0, 28, 320, 200, 256,VESA mode from OEM NVidia F3 ,VESA Color Palette Mode ,4f02,134, 0, 0, 28, 320, 240, 256,VESA mode from OEM NVidia F4 ,VESA Color Palette Mode ,4f02,131, 0, 0, 28, 320, 400, 256,VESA mode from OEM NVidia F5 ,VESA Color Palette Mode ,4f02,100, 0, 0, 28, 640, 400, 256,VESA mode from OEM NVidia F6 ,VESA Color Palette Mode ,4f02,101, 0, 0, 28, 640, 480, 256,VESA mode from OEM NVidia F7 ,VESA Color Palette Mode ,4f02,103, 0, 0, 28, 800, 600, 256,VESA mode from OEM NVidia F8 ,VESA Color Palette Mode ,4f02,105, 0, 0, 28,1024, 768, 256,VESA mode from OEM NVidia F9 ,VESA Color Palette Mode ,4f02,107, 0, 0, 28,1280,1024, 256,VESA mode from OEM NVidia F10 ,VESA Color Palette Mode ,4f02,147, 0, 0, 28,1400,1050, 256,VESA mode from OEM NVidia SF1 ,VESA Color Palette Mode ,4f02,145, 0, 0, 28,1600,1200, 256,VESA mode from OEM NVidia SF2 ,VESA RGB 565 ,4f02,10E, 0, 0, 28, 320, 200, 64k,VESA mode from OEM NVidia SF3 ,VESA RGB 565 ,4f02,135, 0, 0, 28, 320, 240, 64k,VESA mode from OEM NVidia SF4 ,VESA RGB 565 ,4f02,132, 0, 0, 28, 320, 400, 64k,VESA mode from OEM NVidia SF5 ,VESA RGB 565 ,4f02,13D, 0, 0, 28, 640, 400, 64k,VESA mode from OEM NVidia SF6 ,VESA RGB 565 ,4f02,111, 0, 0, 28, 640, 480, 64k,VESA mode from OEM NVidia SF7 ,VESA RGB 565 ,4f02,114, 0, 0, 28, 800, 600, 64k,VESA mode from OEM NVidia SF8 ,VESA RGB 565 ,4f02,117, 0, 0, 28,1024, 768, 64k,VESA mode from OEM NVidia SF9 ,VESA RGB 565 ,4f02,11A, 0, 0, 28,1280,1024, 64k,VESA mode from OEM NVidia SF10,VESA RGB 565 ,4f02,148, 0, 0, 28,1400,1050, 64k,VESA mode from OEM NVidia CF1 ,VESA RGB 565 ,4f02,146, 0, 0, 28,1600,1200, 64k,VESA mode from OEM NVidia CF2 ,VESA xRGB 8888 ,4f02,10F, 0, 0, 28, 320, 200, 16m,VESA mode from OEM NVidia CF3 ,VESA xRGB 8888 ,4f02,136, 0, 0, 28, 320, 240, 16m,VESA mode from OEM NVidia CF4 ,VESA xRGB 8888 ,4f02,133, 0, 0, 28, 320, 400, 16m,VESA mode from OEM NVidia CF5 ,VESA xRGB 8888 ,4f02,13E, 0, 0, 28, 640, 400, 16m,VESA mode from OEM NVidia CF6 ,VESA xRGB 8888 ,4f02,112, 0, 0, 28, 640, 480, 16m,VESA mode from OEM NVidia CF7 ,VESA xRGB 8888 ,4f02,115, 0, 0, 28, 800, 600, 16m,VESA mode from OEM NVidia CF8 ,VESA xRGB 8888 ,4f02,118, 0, 0, 28,1024, 768, 16m,VESA mode from OEM NVidia Hope this helps.

julia mandelbrot toggle proposal
by Tim Wegner 19 Oct '02

19 Oct '02

I received an interesting letter from a fractint user Jurgen Wilke in Osnabrueck, Germany. The letter included a floppy disk. I have placed a zip file of the floppy disk at: http://www.fractint.org/ftp/experimental/wilke.zip I would appreciate it if someone would download this file, follow his instructions, and let me know what you think. It involves both running Fractint and a small pascal program - but you don't have to be a programmer to follow his detailed instructions. (I can decipher the calculation the pascal program is doing, but I am missing the big picture of what he is trying to do.) If you don't have Microsoft Word, the instructions are repeated in the pascal source code file, which can be viewed with any text editor. There are a few example images in the archive that look quite interesting. He is proposing to enhance the julia/fractint toggle in Fractint, but I need someone more patient than I am to help me out to understand what he proposes. Also, do any of you live near Osnabrueck?

Dear Fractint users, recently I had the same problem with my GF3Ti and the most interesting video modes that don't work. But: the good old VGA modes and some SVGA modes still work, you have to find out which on your system. Say your machine works well @ 1024x768. Then find an interesting fractal region and then use a RAM/Disk video mode. Remember, Fractint can do images of 4096x4096 like this!!! QAll you have to do is to edit the FRACTINT.CFG and to add your favorite image size. Regards Marc

FOTD 19-10-02 (Atomic Atom [4])
by Jim Muth 19 Oct '02

19 Oct '02

FOTD -- October 19, 2002 (Rating 4) Fractal visionaries and enthusiasts: Mandelbrot midgets are sometimes called atoms. Today's image shows one of these atoms, this one in the fractal that results when a negative portion of Z^1.5 is mixed with half as much negative Z^3, and 1/C is added. But this is not all bad, for though the portions are negative, the result is positive. The atom (midget) at the center is the center of attention. It lies in a spiral in a broad blunt valley of the parent fractal, which is a monstrously bloated, oversized thing that cannot be described, and must be seen to be believed. No wonder I named the image "Atomic Atom". When considering what rating I should give the image, I was struck by the fact that, despite the generating formula and grotesque shape of the parent fractal, today's scene could easily lie in the classic Mandelbrot set. It contains little that cannot be found in the well-known East Valley area of the M-set. I could therefore rate it no higher than a 4, which is only a little below average. And now I must make a confession. I actually had found a far better fractal for today's FOTD, but in my haste I shut down the program without saving the image or parameters, and the image went back to that vast reservoir where undiscovered fractals exist. Oh well, no one is perfect. The render time of 7 minutes from the parameter file is a bit slow, but still reasonable, especially considering that it's Saturday, when many are off from work. And as always, the completed GIF image will promptly be available on Paul's FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Friday here at Fractal Central was a splendid example of Autumn in this part of the world -- deep blue skies filled with fluffy white clouds, invigorating north winds, and a temperature of 59F 15C. The dynamic duo of fractal cats voiced their approval by getting into a noisy quarrel on the porch in the afternoon. Only they know what they started fighting about, but common sense prevailed, and the affair ended before blows were struck. Today is starting cloudy however. I'd better give the grass one final trimming before rain starts to fall. Until tomorrow, take care, and continue taking care.

Tony, Thanks once again for your suggestions. I created a DOS boot disk off of my WIndows 98 machine and added makefcfg.exe to it. It booted fine and ran makefcfg no problem. It seemed to have no trouble finding the video cards VESA settings. Unfortunately, once I rebooted to Windows XP, it still won't run resolutions higher than 640 x 480. I think the only possibility left is to install something like Partition Magic and create a logical drive formatted in FAT16 or 32 and have Fractint reside there. That might work. Bill

FOTD 18-10-02 (Periodicity Ten [7])
by Jim Muth 18 Oct '02

18 Oct '02

FOTD -- October 18, 2002 (Rating 7) Fractal visionaries and enthusiasts: I enjoy surreal art, especially when it speaks of other realities. I also feel that surrealism is not total fantasy, for in all likelihood, other unseen realities surround and enclose our familiar reality much as the planet itself is surrounded and enclosed by space. This belief does not conflict with the critical thinking I mentioned in yesterday's FOTD. Critical thinking does not determine one's world view, rather one's world view determines whether critical thinking can show that person the way to the *entire* truth. Today's critically surreal FOTD image takes us to a totally alien world, where Mandelbrot buds line the ridge of a slight hill, and bits of fractal debris swirl about in the gentle breeze. The entire scene is illuminated by an unseen source of light beyond the left edge of the screen. All that is missing is a bug-eyed alien, and he might pop up over the ridge at any moment. The image has several unusual technical features. To start, other than the few darker green spots with curved edges, the entire scene consists of a blank inside left over from an 'evaporated' fractal. In this case however, the fractal was not evaporated by raising the bailout to a ridiculous level, it was evaporated by dropping the exponents of Z to 0.5 and -0.5, which equals the square root and reciprocal of the square root of Z. Then C was added to complete the iterated expression. I named the image "Periodicity Ten" because its appearance is determined by the setting of the periodicity. It is rare indeed to see an image so greatly controlled by its periodicity. To bring out the details in today's image, I set the inside to < atan >. The other inside fills also give interesting effects, and are well worth a look. The passes must be set to 1 when rendering the image. Otherwise many of the smaller fragments are missed. Unable to decide on the rating of an image so different from my usual fractal fare, I finally decided on an above-average 7. The relatively fast render time of 7-1/2 minutes probably helped in my decision. But even 7 minutes is a bit slow for someone with other more- pressing tasks waiting to be done. So for convenience, the pre-rendered GIF image is available on the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday here at Fractal Central started sunny, but turned cloudy in the afternoon, followed by a moderate shower at 5pm. The dynamic cats had their day's outing early, before the clouds moved in, when it was still sunny and the temperature was 61F 16C. My day's outing must wait until the work is finished however. And before I can finish, I must begin. So until the next FOTD appears in about 24 hours, take care, and be kind to your fractals when they're in critical condition.

Bill: Sometimes XP comes installed with the defaul;t NTFS file system. Dos 7 can only read FAT or FAT32 file systems. If you have a lot of "legacy" software that might not be able to read or see the NTFS file system, then I suggest you re-install WinXP with FAT or FAT32 file system. My preference is FAT32. I think WinXp has some kind of partition utility (NOT FDD) that allows you to set up a second partition and drive in FAT or FAT32. I don't know whether or not you have to delete the first partition If you still have lots of free space on your HDD, you can use a a 3rd party partition utility like PartitionMagic to set up a second drive in FAT or FAT32. I think that even partition Magic allows you to somehow convert partition file systems back and forth. You can then load Fractint once you've created your FAT or FAT32 partition.

Hans, You've had better luck than I have getting Fractint to run on XP. I have just learned that XP can be installed as either NTFS or FAT. My installation is NTFS, which is why I do not see the C: drive when I boot to DOS. Is your machine FAT? Also, do you know how running Virtual PC would affect this? Thanks.

I'd like to hear some you other fractolieri's >reasons for remaining with fractint. In my case, I'm still hobbled by my budget - just can't afford a new machine, and the old one can't run post-3.1 Windoze. Beyond that, there are other reasons that, when I eventually do get a current-tech PC, I will buy UF once and not upgrade. On the pro-Fractint side: - I don't mind doing my layering by hand. - Thanks to Fractint's parsing capability, I can replicate most of UF's capabilities given sufficient time and effort. - Fractint continues to provide me with intriguing images. (http://value.net/~mchris/fractals.htm - some links are broken) - I love Evolver! - And, of course, the two main advantages: it is free and open source. On the anti-UF side: - When UF debuted, I thought "considering the capabilities, it's not a bad deal." Of course then it was $35. Now, it's $50, with a $35 upgrade price tag (that means your old version is worth zero to fifteen dollars on "trade-in", depending on your current version). Ten dollars seems like a more reasonable upgrade fee, especially considering the following: - As with Fractint, UF enhancements are the result of input from an entire community of users. Do the creators of these new tools get a cut of that $35-per-copy added value? One thing that does really bug me: the 6-bit color magnitude. Wouldn't it be possible to create Fractint GIF palettes with 8-bit values? I know it can be done because I use a paint program to tweak certain palette entries for hypertext background images.

Your use of the word 'create' indicates that you see fractals as a means of artistic expression. UF, with its capability for multiple layers, and its transforms and gradients, etc., is the better program for doing 'artistic' things with the underlying fractals, and as such is the program of choice of those who see themselves as fractal artists. On the other hand, I consider myself a fractal explorer and a fractal purist. I do not 'create' fractals; I 'find' them. I try to show as clearly as possible the things that complex numbers do when iterated. I do not want to show how, for artistic purposes, I can distort what the numbers have done. As a DOS program, Fractint is fast, and once the key strokes become familiar, very simple to use. I use it because it best does what I want to do with fractals. Also, the upgrades are frequent and free. Finally, though I use Fractint, I have nothing against UF. Indeed, I sometimes use it to see what lies beyond the resolution limit of Fractint in some of my FOTD images. (Next FOTD in 13 hours!) Jim M.

Hi, Bill, I choose to install XP with the NTFS file system. Since DOS is using the FAT (= file allocation table) system, booting to DOS in fact is resulting in not acknowledging any NTFS drives or partitions. However, this is not affecting the use of Virtual PC! Far as I can see, within or under this virtual machine DOS is running as it always did. (I suppose it would not be different with a FAT-based XP.) Virtual PC is installed and started under and from Windows. As soon as you start it, you can either use your floppy or CD ROM drive (I also use ZIP drives, but did not manage to access them under Virtual PC) to install programs. Another and/or additional option is to configure a second virtual disk - which under Windows is nothing but a directory - to access and exchange files. This is rather convenient.

Maybe it's just a problem with the makecfg program? Maybe if you knew the correct parameters, you could enter them into fractint.cfg by hand? I'm sure that the S3 does support 1600x1200. Do you have any other DOS apps that use 1600x1200 that you could try? I just got my new scanner yesterday and got it working this morning. This was the last thing that was keeping me from upgrading to XP. I am probably still a few weeks away from completing the upgrade and trying Virtual PC, but of course I will post my findings when I do. Nick

Nick, thanks for your useful remarks on VMware and Virtual PC 5.0. Maybe I'll give 5.0 a try - with a trial version first.

I write formulas using the function variables fn1 - fn4. It's then very easy to simply hit Z and keep plugging in different functions and seeing what happens.

However, fractint has features that are missing in UF. One that immediately comes to mind is fractint's support for orbit fractals, e.g., pickover and icons, which I really like. Also, I like the ability to switch resolutions. For example, I run Windows at 1152x864 but I often like to see fractals at 1600x1200. I think it is possible for a Windows program to do this by using DirectX, but I don't think UF supports it. I have just recently downloaded the UF 3 evaluation and am not too familiar with it, so my comments are based on ver. 2. Nick

FOTD 17-10-02 (Mandel Fragments [5])
by Jim Muth 17 Oct '02

17 Oct '02

FOTD -- October 17, 2002 (Rating 5) Fractal visionaries and enthusiasts: There has been a notable lack of critical thinking in the Fractal Central area lately. Critical thinking is what skeptics, as well as fractalists, do so much of, and what believers in unlikely things do so little of. Those who think critically will explain events as simply and rationally as possible. They will not use questionable phenomena such as mental telepathy as an explanation when a normal explanation such as somehow receiving the information through the senses will work as well. There is a good reason for this -- the simplest, most reasonable, explanation is most often the right one. A rash of shootings have taken place in the area lately, and the sniper has so far eluded capture. To me, the explanation is simple -- most likely a very clever maniac is on the loose, or possibly it is the beginning of the next phase of foreign terrorism in the U.S. The shootings are almost certainly not some of the things I have been hearing, such as the beginning of an alien invasion from outer space, or a racist plot to make the ethnically-mixed police department look bad, or a plot to swing the upcoming election in favor of the candidate who wants tighter gun control. I doubt that the shootings are the begin- ning of Armageddon, as I have heard one woman very seriously claim. I wonder how long it will be before the psychics appear on the scene with so many different explanations that one of them is certain to be correct. Oh, we have a fractal today. I named it "Mandel Fragments" because of its extremely fragmentary nature. The generating expression combines various negative portions of Z^(-1.2) and Z^(-11.7). The fractal is then turned outside-in by adding 1/C instead of just plain C. The midget at the center of today's image is a third-order one, lying near the southeast border of a larger midget that lies in the East Valley area of a still larger midget, which in turn lies in a valley of the parent, which consists of oversized but scattered Mandeloid figures. Try as I might, I could see nothing in the final product that is above the long-term FOTD average. I therefore rated it at an average 5. The unreasonably long render time of 1-3/4 hours does nothing to raise the image out of the realm of the mundane. But do not give up hope of seeing the image. Relief will soon arrive in the form of the finished GIF image, which will be available on the FOTD web sites as soon as Paul and Scott can render it. Paul's site may be accessed at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and Scott's at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Wednesday featured, if it could be called a feature, heavy rain, strong winds, and a temperature of 57F 14C. The cats seemed to know early that it would not be an outdoor day, and satisfied themselves watching the raindrops trickle down the windows. Surprisingly, the sun did break through late in the afternoon, though it was still too wet outside for the dynamic duo's paws. Today is beginning much more pleasantly, both for man and cats. The sun is shining, it is warmer, and the amount of work to be done is reasonable. I think it might be a good day. Until tomorrow, take care, and beware of the fractal conspiracy.

I've been experimenting with running Virtual PC 4.3 under XP to find out whether or not I'd be able to make full use of my Pentium4 2 GHz/512 MB RAM machine to accelerate Fractint fractal calculations. Having applied the makefcfg utility to sort out possible VESA problems with my NVidia GeForce4 MX 460 graphics card, I have been able to generate the following resolutions for Fractint (running under DOS under Virtual PC under Windows XP): 640x400x256 640x480x256 800x600x256 1024x768x256 1280x1024x256 With lower or higher resolutions (specified by makefcfg in my fractint.cfg), Virtual PC hung up. I also managed to generate the above resolutions for true colour modes. So, yes, as far as video modes are concerned Virtual PC might be a way to work around the XP limitations. But, there is a but - at least for me. Even calculations of 640x480x256 fractals turned out to be considerably slower than on my Pentium III 700 and 800 MHz PCs. Maybe, there is a way to reconfigure DOS under Virtual PC. I have applied old autoexec.bat and config.sys values from way back when I was really still using DOS, but could not achieve any signficant accelerations. That's why I have given up on trying to run the current Fractint DOS version under XP on my 2 GHz machine. I've decided to wait and hope and pray for the Windows version. Otherwise I'm fine with Fractint on my other PCs (running Windows 98 and ME). Hans-Joachim PS: Something else comes to mind while reporting these experiences with Virtual PC. Has anyone ever tried VMware Workstation? Since it is a virtual machine software letting you run multiple operating systems (like, for instance, Windows and Linux) on a single piece of hardware, maybe it is more useful for running Fractint on modern machines than Virtual PC is.

FOTD 16-10-02 (Mandelbrot Object [7])
by Jim Muth 16 Oct '02

16 Oct '02

FOTD -- October 16, 2002 (Rating 7) Fractal visionaries and enthusiasts: The parent fractal of today's image is a drawn-out string of Mandeloid fractals much like the Hawaiian chain of volcanic islands. Today's image itself is located in a valley of the easternmost and not at all the largest of these Mandeloids. The other Mandeloids are all interesting, and may be visited in future FOTD excursions. The midget at the center of today's FOTD is located in a spiral, the edge of which is cut off by a discontinuity. In keeping with the cutoff theme, the large spiral surrounding the midget is also cut off. The most impressive thing in today's image is the unusually well defined area surrounding the midget. I have emphasized the definition of this area by the coloring I gave to it. The well-defined area reminds me of nothing that I can immediately recognize, yet it seems to be a something. I therefore named the picture "Mandelbrot Object". This name will suffice, though fractals are certainly not objects in the accepted sense of the word. Though I am fairly satisfied with today's image, the coloring still leaves a bit to be desired, especially the outer areas, where the bland beige fails to bring out the full potential of the scene. Also, the midget at the center suffers from too low a maxiter. Considering these shortcomings and the excessive render time of over 1 hour on my machine, I could rate the image no higher than a 7, which is actually quite good. Luckily, the completed image, if it is not already on the FOTD web sites, will soon be available there. The FOTD web sites can be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Tuesday here at Fractal Central was typical of the season, as grey clouds veiled the sun, a cool northerly breeze blew, and the temperature hovered around 55F 13C. The dynamic cats, having seen a TV show about what happens to feral cats in the Australian outback, looked twice before venturing into the holly thicket at the foot of the yard. This morning, the wind is blowing and the rain is pouring. I imagine they will look three times before going outdoors. As for me, the only adventure I want is to complete the day's work with a minimum of trouble, and find a fractal that rates a 9 or 10 for tomorrow's FOTD, which will appear on schedule in roughly 24 hours. Until that apocalyptic moment, take care, and did you know that fractals are good for your health? They're full of isofractones!

FOTD 15-10-02 (Holy Fractal [8])
by Jim Muth 16 Oct '02

16 Oct '02

FOTD -- October 15, 2002 (Rating 8) Fractal visionaries and enthusiasts: Things are getting even tenser here in the F.C. area, with another sniper shooting, the 11th, not too far (50 miles, 80km) away. At times like this, I could ramble on about the human condition, but I'll ramble on about fractals instead. Today's fractal is named "Holy Fractal". This is not because it is in some way connected with a religion, but rather because it is filled with holes. There are thousands of visible holes in the image, and an infinity of invisible holes. And when infinity is mentioned, thoughts of a Deity often arise, so perhaps the title is not as unlikely as first assumed. The scene is located in the East Valley area of a larger midget that exists in the edge chaos of an island that lies in the fractal created when some Z^(-0.008) is combined with Z^(-11) and (1/C) is added. The parent fractal, which is an exaggeration of yesterday's parent, is little more than an immense empty circle with a tiny bit of debris on the western shore. The most surprising thing about it is that, with an exponent of -0.008, it exists at all, but then lots can happen in 10,000 iterations. I have rated the image at an impressive 8. It might not actually be as good as the rating implies, but I like something about it, so the rating of 8 will remain. The 48-minute render time on my Pentium-I 200mhz machine can be reduced to 10 minutes or so on the fastest units. An even faster way of viewing the scene is to download the completed GIF file from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Monday here at the Fractal Emporium spoke of autumn. Crystal blue skies, dry grass, a temperature of 57F 14C and a moderate north breeze combined to give the dynamic duo a near-perfect day in the yard. When they thanked me for their happiness, I gratefully accepted their thanks. I'll be thankful once again when the day's work is finished. Until next time, which will arrive in 24 hours, take care, and where today are all the FOTD fractals that I will find in the days to come?

FOTD 14-10-02 (What is it? [6])
by Jim Muth 14 Oct '02

14 Oct '02

FOTD -- October 14, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's image has been named "What is it?". That is a question. The answer is that today's image is a picture of the midget I spoke of yesterday, which lies just beyond the southeast border of yesterday's "Coronal Globules" image. Curiously enough, since I have rotated the view 180 degrees, yesterday's scene now lies not northwest but southeast of today's. The midget in today's image is one of the more chaotic I have come upon in my travels through the world of fractals. It is quite difficult to find any definite theme that runs throughout the scene. Some areas consist of fractal material so finely ground that it resembles sand. Other areas consist of relatively simple spirals. But the coloring shows that a broad overall pattern does exist around the midget, and that this broad pattern consists of the usual 2,4,8... series of elements. One of the powers of Z in the generating formula is -0.05, which defines a value so close to unity that it might be expected to have little effect on the finished fractal. But the maxiter of today's image is 6000, which gives plenty of iterations in which that tiny departure from unity can build up to a significant change in the overall appearance of the image. Today's image might rate closer to a 5 than a 6. The image is a bit too disorganized to be above average, and it also lacks a theme. But when rating it, I decided to do myself a favor. I'm harsh enough on my fractals as it is. The attached parameter file requires 38 minutes of rendering time on my aging P200 machine. I wonder if it would render in 1/10th the time on a state-of-the-art P4-2000mhz machine. Somehow I doubt it. Those with little to do might run the parameter file, but most will choose to download the completed image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Sunday continued cloudy, with a temperature of 66F 19C, but it did not rain and the grass was dry, and as a result, the dynamic cats had enough quality time in the yard to keep them happy. I now find the work accumulating -- a clear signal to get busy. So until tomorrow, take care, and the search for the last fractal could be a long one.

I have just purchased a new Pentium 4, 1.5 gHz, with the XP Home Edition. Not being able to load the driver for my scanner (new driver versions for XP are not available and will not be), I asked my supplier to install Win98 as a second OS on the system. That should also take care of any potential problems of running Fractint on this new machine. This double OS approach is even suggested on Microsoft's site for users who still want to run older programs which cannot be compatible with XP even with its "compatibility wizard" feature. During the few hours that I managed to 'play' with this new toy, I tried running one of my semi-useless programs performing a calculation and recording the time it takes. This new one took TWICE AS LONG as my current P3-550e! I'm anxious to test if this is due to the XP or the P4. I also intend to test how Fractint speed will be affected.

FOTD 13-10-02 (Coronal Globules [6])
by Jim Muth 13 Oct '02

13 Oct '02

FOTD -- October 13, 2002 (Rating 6) Fractal visionaries and enthusiasts: As viewers and readers of the FOTD know, most of my FOTD images are centered on a quadratic midget that lies in a critical plane of a fractal created by adding two different powers of Z to either C or 1/C. The important word here is 'most'. Occasionally, as in yesterday's 'antlers' image, which showed the entire chaotic part of the fractal, there is no midget to be seen. Today's image is a return to yesterday's fractal. I returned today to search for midgets, and found one that looks as though it is about to vanish beyond the bailout radius. Searching the surroundings of this midget, I found a spot where the entire character of the area suffers a sudden change, and did further searching there. I soon found a midget of apparently average quality. But as I was working with this sub-midget, trying to find something where little existed, the surroundings caught my attention. As I discovered, the interest in this area lies not in the midget, but in its surroundings. I settled on an area to the northwest of the midget, colored it with the < tdis > option, and named the result "Coronal Globules". One glance at the image will reveal why I gave it that name. The original midget is not lost however. It lies a short distance southeast of today's image, and well might appear as a FOTD in the near future. For those (if any) who want to see the rejected midget at once, an outzoom will reveal the exact location, and the midget can then be zoomed in upon. I have rated today's image at a 6, which is a little above average. The render time of 23 minutes is a little below average however. But relief in the form of a pre-rendered image file ready for download is available on the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> If the image is not quite worth 23 minutes of rendering, it is certainly worth a minute or two of download time. The weather Saturday here at Fractal Central was an improvement over the day before, but the temperature of 68F 20C accompanied by fog, drizzle, and most importantly, wet grass, kept the dynamic fractal cats once again confined to the indoors, where their paws and whiskers remained dry. Today appears to be a repeat, so I suspect that before the day is finished, I'll be breaking out a tuna treat for the housebound duo. I'm now going to try to do as little work as possible for the rest of the day, before the more serious work arrives tomorrow. Until next time, in 24 hours, take care, and discipline your fractals with caution.

FOTD 12-10-02 (Antlers in Sight [5])
by Jim Muth 12 Oct '02

12 Oct '02

FOTD -- October 12, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's fractal takes around 0.7 part of Z^(-0.05) and adds 1/10th as much Z^(-11) to it before adding 1/C. The resulting fractal is a grossly bloated empty circle on the verge of turning inside-out, with a bit of chaos on its western shore. Today's image focuses on this chaos, which is filled with curiously twisted quadratic midgets. I may investigate these midgets further in the days to come. Today however, I have concentrated on the entire area of chaos. At first glance, today's scene appears to have L-R symmetry. But the symmetry is an illusion. A second glance will reveal small differences in the left and right halves of the picture. Today's image is rotated 90 degrees and stretched in its vertical direction. This stretching of the chaos distorts it into something that vaguely resembles a rack of moose antlers. When searching for fractal names, if I see even the slightest resemblance to something, that is enough to supply a name. In today's case, it justified the name "Antlers in Sight". The background of the image consists of bof60 inside fill; the ground at the bottom is normal outside material. The whole thing is of average FOTD quality, and in fact, much like the images I produced so many of in the early FOTD's. I rated it at an average 5. The 2-1/2 minute render time is reasonable for such an average image, and that time can be reduced by 40 percent by changing the passes from 1 to g. But even 1-1/2 minutes is a bit longer than would be required to download the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The temperature Friday here at F.C. reached 68F 20C, but the weather was terrible. It poured rain all day, accumulating over 4 inches (or 10cm) by evening. The cats of the fractal variety sat all day on their shelves by the windows, watching the rain and sulking because they could not go out. A treat of tuna in the evening cheered them somewhat, but could not come close to making up for the day of forced confinement. It's still cloudy this morning, though no rain is falling. As soon as the grass dries, the dynamic duo will be unleashed into the yard. (Dynamic fractal cats do not like their paws wet.) As for me, I'm going to take it as slow as possible and enjoy the temporary lull in the work load as much as possible. But unless the world ends, I'll return tomorrow with a new and hopefully better fractal. Until then, take care, and relax.

FOTD 11-10-02 (Complexity [6])
by Jim Muth 11 Oct '02

11 Oct '02

FOTD -- October 11, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's FOTD image is named "Complexity" not because it was created with complex numbers, but rather because it is a very complex image. Much of the complexity has been achieved by rendering the scene with the outside set to <atan> and the inside set to <bof61>. These settings are a departure from my usual equal-iteration bands on the outside and a blank black on the inside. The parent fractal takes 0.0145 part of Z^(11) and adds 1.6095 parts of (1/Z) to it before adding (1/C). The resulting fractal appears as a somewhat distorted M-set rotated 180 degrees. Today's scene is located in some unlikely chaos on a filament of a bud in the East Valley area of the parent, which in today's case is located on the west side of the main bay. In addition to the unusual inside and outside fills in today's image, the bailout also plays a part in the final appearance. I have set the bailout radius to 2.076, which is just above the point where the scene goes totally blank. Unlike fractals with negative exponents of Z, fractals with positive exponents do not evaporate when the bailout is increased. They do change however as the bailout is reduced to near the cutoff point, though to a lesser degree. To see the unchanged version, reset the imag(p3) parameter to zero and recalculate the image. I was about to toss aside today's image with a rating of an average 5, but then I stepped back from the screen and noticed that, from a distance, the image looks surprisingly good. I finally settled on a rating of 6. The render time of 8 minutes from the parameter file is a bit slow. The better way to see the image is to download it in completed form from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday here at the Fractal Central was simply terrible. It rained steadily from dawn until midnight, with a temperature around 61F 16C. This kept the cats confined to the indoors and resulted in them being quite unhappy through most of the day. In the evening, I gave them a treat of turkey, which lightened their moods -- at least a bit. For a change, I have very little to do today, except search for fractals. Since it's still raining, that's probably what I'll do. Until tomorrow, take care, and keep your spirits up -- if you can find them that is.

FOTD 10-10-02 (Inside Fantasy [8])
by Jim Muth 10 Oct '02

10 Oct '02

FOTD -- October 10, 2002 (Rating 8) Fractal visionaries and enthusiasts: Do human beings have spirits? The religious say yes, scientists say they have found no evidence, skeptics say probably not, Atheists say no. I say it depends on the definition of the word 'spirit'. But one thing certain is that some fractals, (those with negative powers of Z), do have spirits, and those spirits remain behind when the original fractal evaporates. As the mention of spirits and the outrageous value of imag(p3) should have made apparent, today's FOTD is another of my 'evaporated' fractals. (To see the unevaporated version, change imag(p3) to 0.) There are no escaping points at all in the image, which consists entirely of trapped inside points made visible by the inside fill of bof61. I used an inside fill of bof61 in today's image because that fill works best with this particular image. I have found no way to predict which inside fill will work best with particular evaporated fractals. The best fill must be found by trial and error. The parent fractal consists of a Mandeloid shaped like a bloated queen termite, with an immense area of chaos to its east. This chaotic area contains regions where the chaos becomes lace-like and converges in nodes. Today's scene lies near one of the most prominent nodes. The actual node of course has long since evap- orated from the world of fractal reality. Since the image is something relatively unique, I rated it at an 8, which is a great improvement over yesterday's miserable 4. I named it "Inside Fantasy" as a description. Considering the much-above-average worth of the finished product, the render time of 6 minutes is reasonable. And as always, the finished GIF image is available for near-instant download on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Wednesday weather here at Fractal Central was of the dull, dreary variety. The lack of sun, temperature of 61F 16C, occasional spits of rain, and the wrong flavor cat food left the fractal cats very testy. In the evening, Tippy defiantly en- sconced himself in my favorite chair, and dared me to try to dislodge him. Tippy won the battle. My next battle will be won when I finish the work now before me. But to finish I must first start, so until tomorrow, when an even better fractal might appear, take care, and prepare for the war against obese fractals.

FOTD 09-10-02 (Floating Garden [4])
by Jim Muth 09 Oct '02

09 Oct '02

FOTD -- October 09, 2002 (Rating 4) Fractal visionaries and enthusiasts: Despite the ridiculous media attention the local area is getting due to the sniper roaming the vicinity, the fractals continue without interruption. (And why are six shootings in a week so newsworthy when we have had 23 shootings in the area on a single week-end, which have received less news coverage?) Before I get side-tracked into social commentary, let's get to the fractals. The name of today's fractal, "Floating Garden", appears rather Japanese, but the image has little in it that could be connected to the orient. It's actually a scene in the fractal created by adding Z^(3) and 3Z^(0.1), then adding C and iterating with the bailout radius set at an unusually low value of 5. (The low bailout makes very little difference.) The resulting fractal appears as a shattered Mandeloid with its main stem pointing north and its East Valley totally broken up. Today's scene is located at the tip of a filament attached to a bud in a spurious valley that lies in the area where East Valley of the parent fractal would normally be located. When rendered in the usual manner, with the outside set to <iter> and the inside set to zero, today's image rates only a 4. With the departures from the normal rendering methods which I used in today's image, it still rates only a 4. When I found the scene, I felt it had a 6 or 7 rated fractal in it. But regardless of what I tried, the stubborn scene just would not improve. I finally settled on the inside fill of bof60, with the outside decorated by the decomp option, which is a feature I have almost never used since I first tried it and quickly grew bored with its effect of curved, shiny metallic surfaces. The name "Floating Garden" was inspired by the curved bits and pieces that appear to be floating in front of a background of infinite space. The visual effect unfortunately does not live up to the above description of the image. The render time of 10 minutes from the parameter file is a bit too much for such a mediocre image. A download of the completed image file is a far more efficient way of seeing the garden. The download may be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> On Tuesday the fractal cats enjoyed the sun, but the temperature in the 50's F, low teens C, was a bit too chilly for their sensitive ears and noses. They spent only 1/2 hour in the yard. Later in the evening, Tippy defiantly grabbed my favorite chair and told me to not even think of moving him. Today it's once again chilly, and with less sun than yesterday, the duo will likely once again be testy. As for me, when undone work lies before me, I'm always testy, so I'd best get started on that undone work. Until tomorrow, take care, and be happy when your work is finished.

FOTD 08-10-02 (Fractal Vines [5])
by Jim Muth 08 Oct '02

08 Oct '02

FOTD -- October 08, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's quickly-found fractal is a simple thing. With the MandelbrotBC1 formula I calculated the Z^(3.01)+C Mandeloid and examined the area of the negative X-axis where the western 'Seahorse' valley is beginning to split. I really had no need for the M-BC1 formula, since I could have done the same thing with Fractint's built-in manzpower formula. The resulting figure would not have been exactly the same, but the character- istics of the midgets in the area would have been similar. As I studied the image, I fancied myself looking down through a jungle of fractal material, toward a cubic midget on the forest floor. I considered naming the image "Fractal Jungle", but the name seemed so obvious that I finally decided on "Fractal Vines". And the name is not too far off the mark. The tangles and loops do resemble vines hanging from trees. Unfortunately, the end result is once again only of average fractal quality, and I could rate it no higher than a 5. While working with fractals, I like to consider the outside parts as material and the inside as empty space, which is why I usually color the inside parts of my fractals a dead black. This viewpoint has become my basic fractal world-view. Surpris- ingly, such a view is not too far removed from what is commonly known as the 'real' world-view, in which a vast empty space is seen as filled with tiny islands of material known as stars, planets, etc., all of which, for convenience, is granted an attribute known as objective reality. And the more one studies the current theories of physics, such as super-strings and super- symmetry, the more one realizes that the 'real' world appears to be made of numbers. Why, I wonder, can't the world of fractals also be considered 'real'. It also is made of numbers; it has its empty spaces and its clumps of 'material'. As the 'real' world needs the human senses to make itself manifest, the fractal world needs compu- ters to make itself manifest. Are the two worlds as different as they seem? Would it truly be so surprising if, when the much publicized 'theory of everything' is finally found, (if it is ever found), it turns out to be a fractal? If all this speculation seems confusing, relief may be found in 5 minutes by rendering the parameter file and watching the festooned vines come into existence, remembering of course that they are vines only because I have declared them to be vines. A quicker, simpler method of viewing the image is to visit Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and download the completed GIF image from there. On Monday, Scott's site got its script signals crossed, but I assume his site is up and running today at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The image may also be downloaded from there. Except for a brief period of cloudiness in the afternoon, the fractal weather Monday here at Fractal Central was ideal. The fractal duo would rather have had more sun, but the temperature of 77F 25C was good enough to keep them in a good humor. Today promises to be a near-perfect repeat, so the dynamic duo should stay happy most all day. My own happiness will come when I finish a bit of work that seems to always appear when I expect a slow day. Until 24 hours or so from now, take care, and think for yourself.

Fractint on XP
by Anna Baron 08 Oct '02

08 Oct '02

I suppose there's no chance fractint could be made to run on XP (nt file system)? Am I really and truly stuck with having to repartition and to dual-boot into Win98/DOS in order to keep fractint? It seems so, as I've been trying hard enough to make it run on my newly purchased machine running xp but it refuses to do so with reports of missing fractint.cfg. I guess no one has a trick up his sleeve that would save me the trouble of wiping off my new system? Cheers, Anna. __________________________________________________ Do You Yahoo!?

I would suggest trying Virtual PC 5.0 (http://www.connectix.com/products/vpc5w.html) This program allows you to run different operating systems (DOS, OS/2, etc.) on top of Windows. It works by virtualizing all the hardware (e.g., it emulates an S3 video card). This product gets good reviews. Some people successfully use it to run DOS games on NT/XP, so it should work with Fractint. Although it is $200, you can download a fully functional free trial. I am going to upgrade from NT to XP in a month or two (I'm waiting on a new slide scanner). After I upgrade, I'm going to try Virtual PC. It would be worth $200 to me to be able to run Fractint, my old DOS programs, and my old OS/2 programs. Of course, I'll report my experience here. Nick

FOTD 07-10-02 (Monarch Butterfractal [5])
by Jim Muth 07 Oct '02

07 Oct '02

FOTD -- October 07, 2002 (Rating 5) Fractal visionaries and enthusiasts: To produce today's fractal, I took Z^(-1.25) and subtracted Z^(-2.75) from it before adding 1/C. With the bailout radius set to 210, this formula draws a parent fractal with a spade- shaped bay whose point faces east. Though the bay is filled with various forms of fractal debris, little of interest lies in this debris. Today's scene is located just north of the eastern point of the parent fractal, where two lacy arms converge. When I saw the image, I was reminded of a monarch butterfly that I had noticed fluttering in the garden earlier in the day. I immediately named the picture "Monarch Butterfractal", and then rated the image an average 5. Like fractals, those butterflies have long been a puzzle to me. They appear every year in late summer and autumn, fluttering around the flowers, storing energy for their migration to the recently-discovered remote mountain valley in Mexico, where they spend the winter in a state of torpor. But how does a single butterfly survive a journey of nearly 5,000 kilometers? Not even considering the hazards along the way, the time needed to complete such a journey would far exceed the life span of a single butterfly. Perhaps the butterflies make the trip in the same manner humanity is supposed to explore interstellar space. The individuals who arrive at the destination are the remote descendants of those who set out on the journey. Or maybe the whole monarch migration story is as much a myth as the idea that humanity one day actually will reach the distant stars. Forgetting butterflies and space exploration, perhaps the best feature of today's image is its lightning speed. It renders in less than one minute on my tired old machine, even in single- pass mode. And as always, the completed image is available on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> And despite recent speculation on another list, Paul is quite alive and active. The fractal weather Sunday here at Fractal Central was crisp and fall-like, with deep blue skies and a temperature of 72F 22C. The cats enjoyed the day lazing all afternoon in the sun on the porch. Unfortunately, with the sun's angle growing lower every day, the holly trees are beginning to cast their shade onto the porch, and soon the cats will have no sun to bask in during the afternoons. Right now, I've got to get busy on a convention program which is a big rush. But then convention programs are usually rush jobs. Well, the best way I know to eliminate the rush is to get busy. Until next time in 24 hours, take care, and before a problem can be solved, it must be understood.

Fractint and Windows XP
by Tony Parker 06 Oct '02

06 Oct '02

Bill: Why don't you swap the "old" video card from your older PC and install it on your "new" PC? You might have to also transfer over the drivers, or download and install "new" XP drivers from the "old" OEMs website. Your problem my be due to the fact that your video card is of the "new" kind that no longer supports the "old style" Vesa video registers. Most of the "older" Nvidia TNT cards still support Vesa registers. The good news about the "older" video cards is that if you can find them they are usually a lot cheaper than the "newer" video cards. A good tip is to check with other members of the fractint list which cards still work with fractint. Some OEMs post the specs of their cards on their websites, so a good policy would be to check a card's specs before buying it. The thing to look for is VESA register support.

FOTD 06-10-02 (Otherworldly Image [7])
by Jim Muth 06 Oct '02

06 Oct '02

FOTD -- October 06, 2002 (Rating 7) Fractal visionaries and enthusiasts: For some reason, I named today's fractal "Otherworldly Image". I forget the reason, but fractals are truly not of this world. How could they be when even the simple fractals I work with exist in four dimensions, and this 'real' world of ours is endowed with only three spatial dimensions? So the name is justified after all. The formula that created today's fractal adds together 8 parts of Z^(-1.3), 2 parts of Z^(-8.3), and one part of (1/C). The location of the image is in a Seahorse-Valley-like area of its multi-bayed parent. In this valley, the filaments extending from buds end in ring-shaped loops with various decorations and open areas along the loops. These ring-like features are very common in fractals that combine two negative powers of Z with the reciprocal of C. In the image, we are looking deep into one of the decorations in the interior of a ring. The ring theme infests the image, which is filled with rings and parts of rings. There are tiny rings at the peaks of the hills, and gigantic rings out beyond the borders of the image. I might have named the image "Ringworld" had that name not already been taken. After a bit of critical consideration, (I CAN think critically), I rated the image at an above-average 7. The coloring at least has somewhat of a theme, and the image is actually rather pleasant to look at. The 9-minute render time from the parameter file is a bit slow, but not beyond reason on a Sunday, the day set aside for fun and rest. The minor task of rendering may be escaped by downloading the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Saturday weather here at Fractal Central turned out to be even warmer than Friday's. The temperature reached 88F 31C, but drier air and a fresh breeze kept things within comfort. Approving of the conditions, the fractal cats spent several hours in the yard, behaving like the angels which they most certainly are not. It is now Sunday morning, and I've got to think of something to do this afternoon that will make the day at least slightly memorable. If I were to find the world's best fractal, that would do it, but if I did find the best fractal, how would I know it? What makes some fractals good and others not as good? If fractals had never been discovered (or invented?) would there still be good and less-good fractals? While I'm pondering these not-quite-monumental questions, I just might go out and have a bit of a good time. Until next time, which will arrive in about 24 hours, take care, and continue the search for eternal, if not universal truth, which, like fractal worth, might also be a by-product of the human way of thinking.

FOTD 05-10-02 (The Great Spirals [5])
by Jim Muth 06 Oct '02

06 Oct '02

FOTD -- October 05, 2002 (Rating 5) Fractal visionaries and enthusiasts: Sometimes, while discussing fractals, I remark that the image on the screen is but a slice through an abstract four-dimensional object. When I say this, the question is often asked, 'where is the fourth dimension?' I then reply by stating that the fourth dimension is sideways to the inside of solid objects, and of course, the person I am talking with remarks that such a direc- tion does not and cannot exist because there is no space for it. The real difficulty with the fourth, and all higher dimensions, is that we cannot visualize them. Early in life, we learn to decipher and organize our sensory input so that it forms in our minds the image a three-dimensional exterior world. The image works quite well because all people, (with the possible excep- tion of the insane), have formed the same image. That world might or might not resemble our mental images of it, but what if, perhaps with the aid of virtual-reality computers, a child in his formative years were fed images of a four-dimensional world. Could that child then grow to visualize four-dimensional space and all the figures that might exist in it? Maybe he could, maybe not. We'll never know because the experi- ment will never be done. But I can't help but wonder whether a three-dimensional reality actually exists 'out there' or whether we learn early in live to organize our mental impressions into a world of three dimensions, and then go on to invent a math- ematics that works with that three-dimensional image. I mention the fourth dimension because it is one of my favorite topics of contemplation when I settle into my ponder chair, and also because in the upcoming FOTD's I will often be discussing the fourth dimension. Today's image is part of a critical Mandel-plane of the four- dimensional julibrot that results when 1 part of Z^2.2, 2.2 parts of Z, and C are added and iterated. The two prominent spirals are impressive, and inspired the name "The Great Spirals". But it takes more than two spirals to make a great fractal, so I could rate the image no more than an average 5. With a render time of 13 minutes, the parameter file is slow. The good news is that the completed GIF image will soon be ready for download on the two FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Friday here at Fractal Central started with low clouds and fog, which then gave way to hazy sun and an afternoon temperature of 81F 27C. Ignoring the high humidity, the cats approved of the conditions, and showed their approval by sitting on the porch, guarding the yard through most of the afternoon. I'm now going to try to take it easy for the rest of the day. If I'm lucky, no work will appear; if I'm unlucky, a few minor tasks might arise. Being a firm believer in Murphy's Law, I expect to be unlucky. In any case, the next FOTD will appear tomorrow around the same time at the same place.

FOTD 04-10-02 (Spritely Iterated [5])
by Jim Muth 05 Oct '02

05 Oct '02

FOTD -- October 04, 2002 (Rating 5) Fractal visionaries and enthusiasts: Today's image pictures a midget that exists 2 turns down the infinite logarithmic spiral of the Z^1.618034 Mandeloid. Or maybe I should say 5.1416... turns down the spiral, because pi is considered ground level. Studying the midget in the image, I saw things such as an undersea creature swimming through the water, or a sprite floating blithely through the air. I finally chose the happy sprite and named the picture "Spritely Iterated." When it came time to rate the image, I tried to see a 6 or 7 rating. But try as I might, I could find nothing above average in the scene, and had to settle on a fully average rating of 5. Being an armchair philosopher who wonders what is real, (the objective universe is far too simple an answer), I found myself pondering the nature of fractals as I studied today's image. When the image of a fractal is on the screen, that image is objective, but what of the reality behind the image? The Mandelbrot set, for example, is not objective, because it has no physical existence, nor is it totally subjective, since pictures of it can be shared the same as any objective thing. I suppose fractals are best considered mathematical abstrac- tions. But they are not true abstractions in the sense that an attribute such as honor is. True abstractions such as honor cannot be pictured. Fractals might be an entirely new form of reality, or non-reality. I must do far more pondering on this fascinating topic. But regardless of what fractals turn out to be, there is an endless supply of them, and I'll continue search- ing for them for quite some time to come. Speaking of time, only 4 minutes of it are required to render today's image from the attached parameter file. And less than half that time is required to download the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and enjoy the spritely midget floating through the aether. The weather Thursday here at F.C. was once again summer-like, with hazy sun, a temperature of 86F 30C, and high humidity. The fractal cats did what they always do on warm summer afternoons -- they slept in their porch chairs until evening, when hunger brought them indoors to cry for food. And if I fail to finish the work now before me, I'll be crying for food before long. So I guess this is the end of the FOTD for another day. Until tomorrow, take care, and are fractals objective, subjective, abstractions, something in between, all of the above, or none of the above?

FOTD 03-10-02 (Julia Railyard [6])
by Jim Muth 03 Oct '02

03 Oct '02

FOTD -- October 03, 2002 (Rating 6) Fractal visionaries and enthusiasts: I do not usually put much effort into searching for Julia sets. It's not that I consider them less interesting, but rather that I spend most of my fractal time searching for quadratic midgets in fractals created by the MandelbrotMix4 formula. Occasionally however, I do venture into Julia territory, (as well as all the other territories that exist in the world of four dimensions). And of all the julia sets I have stumbled upon, none is more curious than the one in today's image. The julia object that fills today's image is truly indescrib- able. It might be some bizarre alien creature from outer space, or some weird heraldry design. Whatever else it resembles, the image is obviously full of the same railway-track filaments that appeared in the 2 most recent FOTD's, and it is these tracks that led to the name "Julia Railyard". At the two main branching points, as well as the smaller points, open rectangles appear. These are virtually perfect rectangles. I know of no more-perfect rectangles in all the world of fractals. In the past, I have posted several FOTD images of strange things that happen to these rectangles when the paramet- ers are changed even slightly, and the even stranger things that happen to the rectangles, as well as the entire Julia fractal, when the view is rotated in the fourth dimension. I have rated the picture a 6, mostly because I am familiar with the scene. If I had just discovered the image, I would have rated it a 7 or 8. No formula is included in the parameter file because it uses the built-in julzpower formula already in the Fractint program. The 1-1/2 minute render time at SF5 resolution is quite reason- able, but as always, the pre-rendered GIF image is available on the WWW at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Wednesday was a bit too warm to be ideal, especially for early October. The temperature of 88F 31C and hot sun kept the dynamic duo in the shade of the holly trees most of the afternoon. Only when the sun left the porch did they return to their porch chairs. And I've got a bit too much work ahead of me for my situation to be considered ideal. But a bit of effort applied in the right places can soon change that situation. Until I get started, I can't get finished however, so until tomorrow, take care, and the fourth dimension was here yesterday.

Re: [Fractint] Fractint and Windows XP
by Tony Parker 03 Oct '02

03 Oct '02

That's not the reason why I suggested that you boot with a Dos or Win95/98 Floppy when trying to reconfigure a new Fractint.cfg file with the makefcfg.exe utility. Many Fractint users have complained that when run under either Win2000 or WinXP, makefcfg.exe might not see the Vesa registers of your video card. If makefcfg.exe can't see your video card's Vesa registers, then the fractint.cfg file won't be able to point Fractint.exe to your video card's Vesa registers. Booting from a Dos or Win95/98 Floppy will hopefully "trick" makefcfg.exe into seeing the vesa registers and it will write you a new frractint.cfg file. Then you can remove the floppy, reboot in Win2000/WinXP and hopefully Fractint will now "see" the Vesa registers of your video card. Then you can make & configure yourself a "Dos Box" to run Fractint.exe under Win2000/WinXP etc....

bessel functions
by Tim Wegner 03 Oct '02

03 Oct '02

I received an email requesting that the complex bessel function be implemented in Fractint. I have a bunch of complex analysis and numerical analysis books I am checking. I also have Numerical Recipes in C, but that code is copyrighted, and also has a poor reputation. Does anyone have either a clear formulation suitable for implementation, or even better, an implementation to contribute? If so, let me know. A Mac program has implemented it. I have emailed the author, but of course I don't know if he'll be interested in contributing his implementation. The web site is here: http://members.optusnet.com.au/~peterstone/parser.html It's hard to tell from these few images if the bessel function would be worth implementing or not. Let me know what you think. Tim

FOTD 02-10-02 (Railyard-II [6])
by Jim Muth 02 Oct '02

02 Oct '02

FOTD -- October 02, 2002 (Rating 6) Fractal visionaries and enthusiasts: Most sequels fall short of the standard set by the original. Today's FOTD fractal image is a sequel to yesterday's "Railyard" image. Whether it equals the worth of that image is up to the viewer to decide, but in my opinion, today's image falls a bit short of yesterday's. I therefore rated it a 6 -- still a bit above average, though not exceptional. I could have named today's image "Son of Railyard" or "Return of the Railyard", or perhaps something more sensational such as "Curse of the Railyard" or "The Railyard Rises Again". But I didn't. I finally decided on the simple descriptive title "Railyard-II" In today's image I subtracted 2Z from Z^2.001 instead of adding it. The parent fractal that results from this change is shifted in position, and now has X-axis symmetry, but it is otherwise little different from the parent of yesterday's image. As in yesterday's image, today's scene is located in the negative-stem area of the parent. I have yet to see a four-dimensional train running along the fractal rails, which twist and curve in 4-D space. As a matter of fact, I have yet to visualize 4-D space. Having firmly established a 3-D world image, I appear to be unable to do so, but despite the seeming impossibility, I never stop trying. And now I hear that perhaps 11 or even more dimensions might exist, all rolled up into tiny supersymmetric strings. (I wonder what they're made of.) It's all very interesting, but what chance do I, a mere human being, have of understanding the world that contains me. (Or is it I who contain the world?) Now that the FOTD is once again an every-day thing, I'll have more opportunity to speculate on the philofractal list about the nature of reality, and perhaps invent some fractal formulae which demonstrate that I am on the right track. About that FOTD CD, it's basically finished, but I want to include on it the FOTD's that will appear during the remainder of this year, so that the disk's contents will end at an obvious break point. The CD will be ready for distribution after the first of next year, and after that I will release a new FOTD CD at the start of every new year. I have not even begun to exhaust my enthusiasm for the FOTD. The parameter file runs in 9 minutes; the completed GIF image downloads in less than one minute. Running the parameter file is more fun; downloading from the web is more convenient. The choice is up to the reader. Those who choose to download will find the image soon available on the web at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Tuesday here at Fractal Central was congruent to Monday's weather, though I doubt that weather can be congruent. One thing certain is that it was similar. The warm sun and temperature of 84F 29C kept the fractal cats outdoors all afternoon, presumably dreaming pleasant dreams. My dreams will be more pleasant when the day's tasks are finished. But achieving that lofty goal will require work, and it's time to get started. So until tomorrow, take care, and have a fractal day.

Re: Bessel Functions

Between now and implementation (and to see whether implementation is worth it): The pictures on the given page are the results of a single transformation of his "8 Sector Map" by the given function (a common technique to draw complex functions of a complex variable, since as a graph it would require four dimensions). For initial experiments, note that Bessel functions of half-integer order are elementary: K (z) = exp(-z)*sqrt(pi/2)*(1+1/z)/sqrt(z) 3/2 Mess with that in a formula to see what one can get. To construct some more, note: J (z) = sqrt(2/(pi*z))sin(z-n*pi/2)*W(n,z)+cos(z-n*pi/2)*V(n,z)/sqrt(2*pi*z^3) n+1/2 where n is an integer, floor(n/2) W(n,z) = SUM ((n+2j)!/((2j)!(n-2j)!)(-1/(4z^2))^j j=0 and floor((n-1)/2) V(n,z) = SUM ((n+2j+1)!/((2j+1)!(n-2j-1)!)(-1/(4z^2))^j j=0

FOTD 01-10-02 (Midget in a railyard [7])
by Jim Muth 01 Oct '02

01 Oct '02

FOTD -- October 01, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today's fractal impresses me as a picture of a midget in the middle of a railway switching yard, surrounded by a maze of railroad tracks. I had little choice but to name the image "Midget in a Railyard". The formula behind the image is Z^2.001+2Z+C, a formula that draws virtually the same fractal as Z^2.001+C. But virtually is not the same as exactly, and there are small differences between the fractals drawn by the two formulae. When Z is added to Z^2 in a formula, the resulting fractal is a classic Mandelbrot set that has shifted its position but not changed its shape. But when Z is added to any other power of Z except 1, the resulting fractal changes shape as well as shifts its position. When the exponent is close to 2, as with the Z^2.001 of today's image, the change is small, but it is there. At first glance, the fractal created by the simple formula Z^2.001+C appears to be a normal M-set, but a closer examination of the negative stem will reveal that the stem has split into an infinitely divided series of filaments resembling curving railroad tracks. These track-like filaments are strung with midgets. In today's image, I have added 2Z to the simple Z^2.001, which further splits the filaments and works even more madness in the area of the negative stem. Today's midget lies on one of these track-like filaments. With a render time of 19 minutes, the parameter file of today's image is rather slow. Turbo speed can be found at the following web sites, where the completed image will soon be posted if it is not already waiting. <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Monday here at Fractal Central was once again near ideal. Warm sun and a temperature of 75F 24C lured the fractal cats once again into the yard, where they explored for an hour before retiring to their favorite chairs to enjoy the sun on the porch. As for me, now that I'm again on a daily FOTD schedule, I'll be writing mostly in the evening hours. Since it's now evening and the day's work is finished, I'll commence the shut-down of the fractal shoppe, turn out the lights, call it a night, and watch the end of the Ravens' football game. (We're winning!) Until tomorrow around this same time, take care, and never lose your sense of wonder.

FOTD 30-09-02 (Scrambled Thoughts [7])
by Jim Muth 30 Sep '02

30 Sep '02

FOTD -- September 30, 2002 (Rating 7) Fractal visionaries and enthusiasts: Good news! . . . At least for fans of fractals. This is the last time the FOTD will appear only on even-numbered days. Starting tomorrow, October 1, I will resume posting the FOTD on a daily basis. I shall also resume posting some of my philosophical musings to the philofractal list, where those who suspect that I am confused can confirm their suspicions. One thing that I am not confused about however is today's fractal, which rates an honest 7. The formula behind the image combines 4 parts of Z^(-1.5) with 1 part of Z^(-5) to produce an indescribable parent fractal in an unlikely part of which today's scene is located. When two negative powers of Z are combined and iterated, as is done in today's image, very unusual fractals result -- fractals which are unusual not only in their overall shape, but in their inner details as well. In today's image for example, the default equal-iteration bands make an image so striking and so unique that no special coloring algorithms are needed. For some strange reason, today's image, with its features edged in glowing gold, reminds me of scrambled eggs, I originally named the image "Scrambled Fractal", but then, unable to justify the name I had given, I changed the name to scrambled thoughts, which I am accused often enough of having. Slow images are not always the best. This is proved by the surprisingly brief render time of today's image, which is a mere 2 minutes on my P200 machine. And as always, the completed GIF file of the image is available on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Sunday, (if anyone doubts that weather is fractal, let them look at a weather chart), here at Fractal Central was of the ideal Autumn variety. The two fractal cats enjoyed the warm sun and temperature of 75F 24C to the maximum extent possible, though I am sure they would have enjoyed it even more if they were 8 years younger. As for me, what I need is a day or two of nothing to do but ponder the mysteries of the universe. The only trouble with pondering is that so many seem to disagree with the conclusions I reach when I ponder. But right now, it is Sunday evening, and I must ponder how I shall end the day. So until tomorrow, same time same place, take care, and what use is there in solving the mysteries of the universe if no one believes the answers?

FOTD 28-09-02 (Gold Necklace [6])
by Jim Muth 28 Sep '02

28 Sep '02

FOTD -- September 28, 2002 (Rating 6) Fractal visionaries and enthusiasts: The formula of today's image takes 0.2 parts of Z^(-3.16227766), which is the square root of 10, and adds it to three times as much Z^(-0.316227766), which is 1/10th of the first number and also its reciprocal. The resulting fractal is a bloated, vaguely Mandel-shaped thing with a double valley on the west side and a smoothly curved shoreline on the east side. Two full out-zooms are needed to see the entire fractal. The only real area of interest is the vicinity of the double valley, and today's image is located a short distance inland from the southern shoreline of this valley. I named the image "Gold Necklace", mostly because I could think of nothing better. The name is not totally frivolous however, because the effect of the intricate gold filaments against a dull blue background does vaguely suggest a gold chain. In my opinion, the image rates a 6, which is not great, but keeps my (IMO) long string of above-average images intact. And the render time of 5 minutes is just within the bounds of reason. An even faster way of seeing the image is to go to Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and download the completed GIF image from there. The weather here at Fractal Central on Friday was variable. The day started chilly and foggy, but in the early afternoon the fog lifted, the clouds broke, and the temperature rose into the low 80'sF, or around 28C. Unfortunately, the extreme humidity made for rather oppressive conditions. Not enjoying humidity, and being especially adverse to wet grass, the fractal cats spent the afternoon in their porch chairs, avoiding the condensation on the still-cold concrete floor. In the evening, a short but intense shower passed over, which ended the day with a bang and sent the cats scurrying indoors. And I had better scurry if I want to put the little bit of work now on my desk behind me. But never fear, for though I leave now, I shall return in two days, on the 30th, with a new and hopefully improved FOTD image. Until then, take care, and be of stout mind but lean heart.
