Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: The end of the work back-up is in sight, but it is not yet here, and I have a job that is due by 5pm today. So today's discussion will be another terse one. The parent fractal was created by combining negative portions of Z^(0.996) and Z^(-1.004), then adding (1/C). The scene is located near the point where a filament extending from a bud vanishes behind a foreground disk. I rendered the image with the outside set to 'summ', which I believe refers to the sum of the 'real' and 'imag' components. I named it "Summation" because the 'summ' option was used. When studying the image, I decided that it was at least slightly above average, and gave it a rating of a 6. The render time of 7 minutes results in an overall value of 85. The overall value becomes meaningless when the completed GIF image is downloaded from the FOTD web site at: Except for a brief thunder-shower Wednesday evening, things were pretty good here at Fractal Central both Wednesday and Thursday. The cat duo agreed, and enjoyed two pleasant afternoons in the holly thicket. I also enjoyed the two days, mostly because the work went well. Today is starting sunny and hot. I will be indoors most of the day, but how will the cats cope with the heat? Only time will tell. If all goes well, I will return in 2 days with the next FOEFD. Until then, take care, but don't be too careful. Jim Muth jamth@mindspring.com jimmuth@aol.com |
