FOTD -- July 20, 2005 (Rating 4) Fractal visionaries and enthusiasts: After yesterday's abysmal effort, I had hoped to have a better fractal for today. The fractal is better, true enough, but how much praise can I give an image that rates a humble 4? We will need to do better still in the next FOTD. In today's image I set the outside to the 'epsiloncross' option, an option I rarely use. The result is an image with black arcs that seem to be holding hot magma in place. I named the image "Iterative Eruption". It was created by combining various portions of Z^(-2.2) and Z^(-1.2), then adding (1/C). The render time of 3-1/2 minutes is within reason, but the 'passes=g' option will cut another minute from that time. Perhaps the fastest way to see the image is to download it already rendered from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A temperature of 93F 34C combined with a hot sun was too much for the fractal cats on Tuesday. They passed most of the day indoors under the air conditioner, going outside only long enough to convince themselves that the indoors was the better choice. A tough looking tomcat wandering the area might have helped them decide to stay inside. Today is starting with sun and clouds, still hot but less humid. The cats have yet to decide what to do. I have no problem deciding what to do. Having one's work pre- arranged is one of the benefits of adulthood. The next fractal will appear in 24 or so hours. Until then, take care, and get in there with the big time thinkers.
