FOTD 06-10-04 (Scrap Fractal [4])
FOTD -- October 06, 2004 (Rating 4) Fractal visionaries and enthusiasts: Today's fractal image, created by the barnsleym1 formula, resembles little more than a texture. In fact, it is hardly a texture. The image could more accurately be described as resembling a patch of pollution floating on the surface of a pond, or even something unmentionable. I named the image "Scrap Fractal" during a moment of kindness. One thing the image has going for it is the fact that I know of no other formula that could produce such chaotic chaos. Of course, I say this while having yet to examine the other two Barnsley Mandelbrot formulas, so I cannot state it as a fact. The default image drawn by the barnsleym1 formula has XY-axis symmetry, but no signs of midgets. Changing the starting point from 0,0 results in fractals without symmetry, which could be considered more interesting, but the inner details remain pretty much the same. None of the starting points I tried gave even a hint of a Mandelbrot midget. If such midgets can be created by this formula, they have so far totally eluded me. When coloring the scene I tried the sky-blue-background effect. No coloring can raise a pile of scrap to a jewel, but the sky- blue emphasized the forces working in the debris and raised the rating from a shameful 3 to a below-average 4. The render time is once again very fast. All the Barnsley formulas are fast. Today's render time of 1 minute and 50.78 seconds lets the overall value of the image come in at a whopping 216, a high enough value to make running the included parameter file practical. The completed image is or soon will be available for viewing on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> I found only a few minutes to browse the Sep-Oct issue of 'Skeptical Inquirer' magazine yesterday, but one thing I did notice was an unfavorable (no surprise) review of the cult-like movie 'What the Bleep do we Know?'. The review is actually more of an attack on the film's producers, who are portrayed as new- age kooks, than a refutation of its content, which apparently connects quantum mechanics with mysticism. This leads me to take the film more seriously. If the film's content were total kookiness, CSICOP, which publishes S.I. magazine, would have pointed out its scientific errors, and would not have needed to attack the character of its producers. Actually, the more I read this magazine, which sometimes seems almost desperate in its denial of the paranormal, the more I become convinced that precognition is not the only paranormal thing that really does exist. I must search to see if the film has a web site. Despite the temperature of only 59F 15C and chilly winds here at Fractal Central on Tuesday, the duo of cats had a pleasant day. Thomas actually tried to make friends with the new guy on the block -- a grey-and-white cat from three doors down the hill -- but the other cat sneaked off. Tippy watched the lack of action with dis-interest. Today is starting quite chilly, but the wind has abated and the sun is bright. I expect a warmer afternoon. For me the work is still light, which promises as good a fractal as I can find in the second Barnsley Mandelbrot formula. That image will appear in 24 hours. Until then, take care, and don't doubt that fractals are good for your health.

One or more of them are good for high frequency (detailed) noise, and they were recommended in the documentation somewhere for that reason as a basis for random dot stereograms. I do happen to hav written a formula that is expressly for the purpose of making things that look like a television set to a channel not in use. Prand { ; This pseudo-random number jenerator seems to hav ; a flat distribution, excepting zero. The only ; thing I might add in compiled code is feedback ; from previous pixels, especially ; since this would get different results from different ; rendering methods like diffusion, but the difference ; shouldn't be discernible if the PRNG method is good. z=|scrnpix * flip(scrnmax) / pixel|, z = z*509, temp = z / 257, z = (temp - trunc(temp)) * 257, iter=iter-iter: iter=iter+1 z > iter } Xplode {z=fn1(pixel), c=fn2(pixel), iter=(0,0): ; This formula is in the same prand.par for no good reason, ; except that it revamps some experiments I was doing a long ; time ago. iter=iter+P1 z = z^iter+ c |z| <= |P2| }

At Rosario's last night, I happened upon a comment to the effect that Ralph Nader didn't need to be Nostradamus to predict that he would not become president. At that same karaoke bar, I happened upon some program called "Abused News". In Edmonton, that's 211 on the phone, which is our distress line for callers who need help, but not from the cops, or the fire department, or the paramedics, at least not yet. You don't need to be Betazoid to _predict_ that 911 operators listen in if they don't offer advice.

I prefer "snuck". I think my preference has to do with the fact that a kay and a dee can't actually be part of the same consonant cluster at the end or the beginning of a syllable. Poets have every right to put an apostrophe in the word to cast it as two syllables, even when such casting actually wrecks the meter of a poem.

comment { On Wed, 6 Oct 2004, Jim Muth wrote the subject of this message, and some of the parameters. altern.map makes Muth's look a bit like ice crystals if I cut down the iteration maximum. The only reason that changes the colouring is because of the logmap. diag.map , methinks, makes the best impression on me, and it's one of those maps that makes carries or wrapping of the iteration count visible, but not on an image like this (I use diag.map and the negative of it interchangeably). Fine textures are one of the few things that _require_ the high quality rendering methods like 1-pass, 2-pass, and tesseral, in about that order. Periodicity checking is _always_ an approximation, especially with fine textures, so it's counter-productive to use it with the slowest rendering method. } Camouflazh { reset=2003 type=barnsleym1 passes=2 center-mag=+1.00799251309293500/-0.27852302220653800/419.8787/1/-90/3.\ 88578058618804789e-016 params=0/0.7 float=y maxiter=255 bailout=9 inside=255 logmap=101 periodicity=0 colors=zzz000<3>e00o00z00<3>zRRzYYzddzkkzrr<3>zcSz_LzWEzS7zO0<3>_E0TB0\ M90F60830<3>ZP0eV0l_0se0zk1<3>zqSzsYztdzvkzxr<3>vySuyLtyEsy7rz0<3>V_0P\ T0JM0DF0780<3>KZ1Ne1Ql1Ts1Xz2<3>izSlzZozdrzkvzr<3>ZzTTzMNzGHz9Az2<3>6_\ 25T24M23F2281<3>2Z92eB2lD2sF3zI<3>Xzcczikznrztrzt<3>TzlNzjGzhAzf3zd<3>\ 2WL2OG1GB186186<3>2ZY2ed3lk3sr4zz<3>Xzzczzkzzrzzrzz<3>UpzOnzHkzBiz4fz<\ 3>2MW2HO1BG168168<3>3DZ3Fe4Hl4Js5Lz<3>Yezdjzkozrtzrtz<3>XVzSPzMIzHCzB5\ z<3>63W52O32G218218<3>H3ZL4eP4lT5sX6z<3>kYzndzrkzvrzvrz<3>tVztPzsJzsDz\ r7z<3>S4WL3OE2G718718<3>Z4Te4Yl5cs6hz7n<3>zZtzeuzlwzsxzsx<3>zWizQezKaz\ EYz8U<6>814814 } Asteroid Collision { reset=2003 type=barnsleym1 passes=2 center-mag=+1.00799251309293500/-0.27852302220653800/419.8787/1/-90/3.\ 88578058618804789e-016 params=0/0.7 float=y maxiter=255 bailout=9 inside=255 periodicity=0 colors=zzz000<3>e00o00z00<3>zRRzYYzddzkkzrr<3>zcSz_LzWEzS7zO0<3>_E0TB0\ M90F60830<3>ZP0eV0l_0se0zk1<3>zqSzsYztdzvkzxr<3>vySuyLtyEsy7rz0<3>V_0P\ T0JM0DF0780<3>KZ1Ne1Ql1Ts1Xz2<3>izSlzZozdrzkvzr<3>ZzTTzMNzGHz9Az2<3>6_\ 25T24M23F2281<3>2Z92eB2lD2sF3zI<3>Xzcczikznrztrzt<3>TzlNzjGzhAzf3zd<3>\ 2WL2OG1GB186186<3>2ZY2ed3lk3sr4zz<3>Xzzczzkzzrzzrzz<3>UpzOnzHkzBiz4fz<\ 3>2MW2HO1BG168168<3>3DZ3Fe4Hl4Js5Lz<3>Yezdjzkozrtzrtz<3>XVzSPzMIzHCzB5\ z<3>63W52O32G218218<3>H3ZL4eP4lT5sX6z<3>kYzndzrkzvrzvrz<3>tVztPzsJzsDz\ r7z<3>S4WL3OE2G718718<3>Z4Te4Yl5cs6hz7n<3>zZtzeuzlwzsxzsx<3>zWizQezKaz\ EYz8U<6>814814 }
