Fractal of the Day

Fractal visionaries: Today's prize-winner fractal is named in honor of that not quite so famous American abstract artist, J. Pollock. The resemblance to the paint drippings which made him famous is quite apparent. I achieved such an effect by taking a nondescript Rectangular plane fractal and redoing it with the inside fill set to epsilon cross. I'm not sure how this option achieves its effects. I think it colors the image according to whether the points' orbits come closest to the real or imag axis. Until recently I had never used this option, considering such a fancy fill method artificial, but I have now had second thoughts about fractals. There is no such thing as a "natural" or "pure" fractal other than the bare formula. And since a natural fractal doesn't exist, it makes no sense to try to maintain fractal purity. And since I no longer must try to keep my fractals pure, I will be able to use the entire range of Fractint's coloring options without compunction. For best effect, today's fractal should be drawn at a minimum resolution of 1024x768. The finished image has been posted to a.b.p.f. and a.f.p. and is available at: Until tomorrow then, may your fractals be infinitely beautiful. Jim Muth jamth@mindspring.com |
