FOTD -- September 21, 2004 (Rating 4) Fractal visionaries and enthusiasts: Over the past several days I have been trying different things with the 3200mhz machine I recently purchased for business purposes, to see how fast I could get it to render fractals. I got so involved in the project that I neglected the FOTD. Since the new P4-3200 unit is 16 times as fast as the old P200 fractal- dedicated machine, it would appear to be able to calculate fractals in 1/16 the time, but so far I have managed only an 8x increase in speed, which is actually a bit better than I had expected. I suspect that, though the new unit runs 16 times as many cycles per second, each cycle does only half as much work. The 8x increase in fractal speed might be all I'll get from the new machine. This is of little importance, for it will be quite some time before the new unit will be available full-time for fractals. Today's fractal image lies in the fractal that results when the Mandelbrot formula Z^1.5+C is calculated 13 levels down the complex logarithmic hyperspiral. The parent fractal looks some- thing like a little man in a racing car (It reminds me of Smokey Stover for those old enough to remember). The image is located in a prominent valley on the southern shore of the parent. I named the picture "Circled by Limes" because of the lime-green circular spiral basins that surround the midget at the center. While searching for a rating, I could find little out of the ordinary that might make the image an above-average one. As a result, I was able to give it a rating no higher than a 4. But that lowly rating is raised to an overall value of 95 by the relatively short render time of 4+ minutes. While rendering a fractal for oneself is the most fun, seeing the completed image is more convenient. The completed image may be conveniently found on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Friday was showery here at Fractal Central; Saturday was cloudy, windy and chilly. But Sunday and Monday were ideal for cats, who took full advantage of the ideal conditions by spending almost the entire two days hiding in the holly patch at the bottom of the yard, cleverly avoiding the burdock burrs. Today is again starting ideally. The cats should be happy. If I had not started trying things with the new computer, the work backlog would have been under control. But as it is, the work is still a bit behind. A week or so of effort should bring it under control however. The next fractal will appear in two days on Sep 23. Until then, take care, and never lose your sense of fractal wonder.
