FOTD -- July 30, 2002 (Rating 8) Fractal visionaries and enthusiasts: Today's fractal reminds me of another real-world object. In this case, I see the graceful swaying of seaweed, a few meters under the surface near some tropical shore. The scene is also filled with schools of small, colorful tropical fish, though these are more difficult to pick out. With all this underwater activity in mind, I named the image "Aquatic Life". Then I stepped back to evaluate the result. After much mental wrestling, I rated the image a much-above- average 8. The formula of the aquatic scene is Z^(-1.1)+Z^(-11)+(1/C), a simple expression that does more than it should. But as I stated recently, it is not the formula that works the magic; it is the 280 iterations. The parent fractal of today's scene appears as a large open bay with many buds and valleys around its perimeter. Today's scene is located in the center of a blunt valley on the south shore of the main bay. The aquatic effect was achieved by rendering the scene with the outside set to the <tdis> option, followed by careful coloring. The render time of just over 1 minute makes running the attached parameter file the quickest way of seeing the seaweed. But downloading the completed GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> might be a lot more fun. The weather Monday here at the (IMO) center of the fractal world was hot, hot, hot. A breeze and slightly lower humidity made it feel less oppressive than it otherwise might have been, but 100F 38C is still hot -- there's no escaping it. The heat was so severe that it buckled the rails of a local rail line, causing a train to derail. The dynamic fractal cats avoided the excessive heat by passing the day in the air-cooled indoors, though they did check several times just to be sure it really was that hot outside. Today is Tuesday, and it's another scorcher -- a perfect excuse for me to stay indoors and get a little ahead on the upcoming convention program that needs to be finished within a week. Until next time, which will come in 3 days on August 2, take care, and why are tropical shores with all their humidity and heat considered paradise on earth?.
