Fractal of the Day

Fractal visionaries and enthusiasts: Today's image is a further investigation of the tree effect that appeared in yesterday's FOTD picture. I lowered the exponent of (-Z) from 1.1 to 1.08 and drew a slice rotated 30 degrees from the Elliptic direction toward the Parabolic direction. In this direction the tree effect is still very prominent, and in addition the trees have an irregular shape more like actual trees. The effect of the lesser exponent is visible in the smaller, more delicate branches on the tree. Since such a tree is so unexpected, I named the picture "Magical Tree" and gave it a somewhat above average rating of 6. The coloring is intended as more of a design than an effort to achieve the appearance of a real tree. And no, I used no third-party graphic program to liven up the color palette, as I sometimes do. To run today's parameter file, patch 13 of Fractint V-20, which has two more complex parameter entries, must be used. The file is available at http://www.fractint.org/ftp/ the name of the file is fradev20.0.13.zip The parameter file runs in 9 minutes once the correct version of Fractint is obtained. And if this is too much trouble, the pre-rendered GIF file of the image is ready for download at: The fractal weather today was sunny, with a temperature of 88F (31C), which pleased the cats so much that they slept all afternoon. A tiny bit of philosophy appeared this morning, but far more is cooking, and could be ready for dissemination any day now. Until tomorrow, take care, and see you in 24 hours.
