FOTD -- April 24, 2005 (Rating 7) Fractal visionaries and enthusiasts: Today's image is named "What's up Doctor?". This has nothing to do with a certain well-known rabbit. I simply gave it that name because these words were the first to come to mind when I saw the image. (Sometimes I like to leave the room while fast fractals are rendering, and give myself a surprise when I return.) And let's face it, the image is unusual enough to justify the name. The parent fractal, which combines negative portions of Z^(-1.5) and Z^(-3.5), then adds (1/C), is one of those huge sprawling affairs that needs an outzoom before it fits onto the screen. Today's scene is found in the vicinity of a valley, which the parent fractal has many of. Surprisingly, the image was rendered with the outside set to the ancient setting of 'iter'. (No one uses that setting nowadays. We have long ago seen all it has to offer, and far better things are available.) The image is good enough to earn its rating of 7. Its render time of 2-1/2 minutes can be cut to 1-1/2 minutes by switching the passes to g. And if all else fails, the image may be down- loaded from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Saturday turned out better than expected here at Fractal Central, with ample afternoon sun and a high temperature of 72F 22C. True, a thunder-storm moved in at 6pm, with wind, heavy rain, pea-sized hail and crackling lightning, but by then the cats had completed their daily adventure in the outdoors, and had taken shelter in the large closet. This morning is starting sunny but quite a bit cooler. It should be good enough for the duo. A book arrived in the mail yesterday, "The Road to Reality" by Penrose, which looks quite interesting. I think I'll give it a quick read (if possible) before continuing with my speculative philosophy. There might be something in it that will change one of my opinions. The next FOTD fractal will appear 24 hours from now. Until then, take care, and maybe the reason we can't find reality is because nothing is real.
