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.

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
