Fractal of the Day

Fractal visionaries and enthusiasts: Yesterday's FOTD showed a midget deep in a tiny valley on the NW shore of the main lake. It was an interesting display of life in a zone where chaos is becoming rampant, but has not yet completely taken over. The image took 49 minutes to render at SF5 on my P200 machine. Today's FOTD moves us deep into another tiny valley, this one very deep in on the south shore of East Valley, where the elements are pinched off. I started the rendering out of curiosity; by the time the image had finished, I was sorry I had started it. Demanding a maxiter of 12-million, the image took 4 hours and 48 minutes to complete on my tired old fractal machine, even at the basic resolution of SF5, which is 640x480, with 256-colors. When the image finally finished, I found myself faced with a different kind of quasi-chaos. Instead of lightning-like arms and filaments, I found rows of roughly circular elements strung together in string-of-pearl-like spirals. I used the same color map that I had used on yesterday's 'midnight' image, so that a better comparison of the two scenes could be made. To name the image, I studied it a few minutes. At first I saw the strings of pearls, then the pearls became segments of caterpillars, and I had found my name. "Fractal Caterpillars" serves quite well as a descriptive name for today's image. I could rate the effort at only a 6, since it's a little too much of a good thing. I'm thinking of purchasing another fractal computer, a state-of-the-art machine, so I would be interested in hearing reports of the time required to render today's particularly difficult scene on different machines with different CPU's. If I do make the purchase, I want to be sure I'm getting the fastest fractal rendering machine possible. Because the rendering time of today's image is so long, I sent the parameter file to Paul a few hours ago so that he can have the image already rendered and ready to post when this discussion arrives. Paul's FOTD web site is at: The fractal weather today was muggy and 91F (33C), climaxed by a heavy thunder-storm in the evening, and followed by a cool night. The fractal cats were too busy sleeping all day to give much response. And it's now time to start another day. I wonder whether the cats will again sleep away most of the day. I'll let you know next time. Until then, take care, and I'd bet that tomorrow's FOTD will be faster than today's. Jim Muth jamth@mindspring.com |
