Fractal of the Day
by Jim Muth
|
|
Fractal visionaries and enthusiasts: I appear to be on a roll. One above-average fractal after another keeps turning up. In keeping with the trend, today's image, which for lack of a better idea has been named "Abstraction 01", rates an above-average 7. The formula of today's scene is Z^1.03-Z^(-1.5)+(1/C). The calculation was once again done by the mysterious MandelbrotMix4 formula, which appears strange but produces midgets by the thousands. The parameter file finishes in 12-1/2 minutes on a reasonably fast Pentium. The image file downloads much faster from: The fractal weather today was sunny but with puffy white clouds, and a temperature of 57F (14C), which was barely warm enough for the fractal cats. I wish my philosophizing were doing as well as my fractal searching. Once again I failed to find the inspiration to write. But I'll try again tomorrow. Until then, take care, and what did we do with our idle time before fractals existed? Jim Muth jamth@mindspring.com |
