Fractal of the Day
by Jim Muth
|
|
Fractal visionaries and enthusiasts: For the third day in a row we have an image with no equal iteration bands on the outside. Instead, I have rendered the outside area with the tdis option. The effect is quite striking, and rates a slightly exaggerated 8. I named the image "Best of the Lot" because I chose it from several fractals I had filed away for a busy day such as today. The formula -14(1/Z)+1.4Z+(1/C) created the image, which renders from the parameter file in a little under 8 minutes. If running the parameter file is inconvenient, the GIF image will soon be available at: The fractal weather today here at fractal central was sunny but cold. The temperature of 37F (3C) kept the fractal cats indoors. As one may surmise from the brevity of this discussion, I am very busy today. I will be busy again tomorrow, but regardless, I'll still have a fractal to enjoy at that time. Until then, take care, and fractals are forever. Jim Muth jamth@mindspring.com |
