Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: For today's FOTD fractal I simply changed the 2's of yesterday's formula to 3's. Some adjusting of real(p3) was necessary to produce a promising fractal. The fractal that resulted is an oversized circle filled with debris. Today's scene is located at the bottom edge of this bloated circle. I named the image "Down Down Down" because while studying it for a name, I had the impression of looking down at the burning coals of a fiery pit, maybe not the pit ruled by Hades, god of the underworld, but fiery nonetheless. The image has little going for it other than the effect of a bed of glowing coals toward the center, thus I could rate it no higher than a 5. But, rendering as it does in less than 2 minutes, the image at least will consume little of the time of those who choose to run the parameter file. As always, the completed GIF image is available at: The Friday weather was typical of the season here at Fractal Central, with clouds, sun, wind, flurries of snow, and a high temperature of 38F 3C. Despite the chill, the fractal cats managed over an hour in the outdoors. When they came in, they were both happy and hungry. I have a relatively slow day ahead of me, which should give time for an above average fractal for tomorrow. Until then, take care, and I've found a projective plane, but it's too large to fit on the shelf beside my Klein bottle. Jim Muth jamth@mindspring.com jimmuth@aol.com |
