FOTD -- October 22, 2004 (Rating 7) Fractal visionaries and enthusiasts: I named today's unusual image, which was created by the 'julfn+exp' formula, "Moire Fantasy" because of the Moire interference patterns that exist all through it. This means that the appearance of the image is partly created by the screen resolution, and the image will therefore appear slightly different at different resolutions. The passes=b option works unusually well with today's image. Not only is it the fastest, but it is by far the most interest- ing to watch in action. The banded effect was achieved by rendering the scene with the outside set to 'summ', an option that I rarely use, but like the passes=b, one that works quite well with today's image. The function I chose for today's image is the 'abs', which changes the negative and imaginary values to positive values. This particular function works best with the julfn+exp formula. I know of no other formula in which the absolute value function works best. The image is different enough from my usual type of fractals to rate a 7. I almost rated it at an 8, but when I could pin down nothing in it actually well above average, finally decided on the 7. When the short render time of 1-1/2 minutes is figured in, the overall worth registers an impressive 435. The completed GIF image is available at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A cloudy and drizzly day here at Fractal Central on Thursday, with a temperature of 50F 10C, kept the dynamic fractal cats stranded indoors for the second straight day. But once again their moods were surprisingly good, and no special treat was needed. Today is again starting cloudy and cool. I expect the cats to have a similar day. For me it looks like an average day, with enough work to keep me busy several hours before I can turn to the world of fractals. The next FOTD will appear tomorrow. Until then, take care, and believe what you will, but be sure to believe something.
