FOTD -- July 29, 2007 (Rating 7) Fractal visionaries and enthusiasts: Before I begin today's discussion, I must warn that there is a bug in the parameter file. When the image is run directly from the parameter file, the imag(p3) parameter comes up as some ridiculous negative number, resulting in a blank screen. To see the correct image, the imag(p3) parameter must be re-entered by hand to the correct value of 3900000000 or 3.9e+009. When this is done, the image generates normally. I have no idea what the bug is. And my apologies for the late FOTD. Fractal lady and I decided to take the day off on Saturday to enjoy the countryside. We did so much enjoying that it was almost 11pm when we made it back exhausted to Fractal Central. For today's fractal we return to the MandAutoCritInZ formula, and check the fractal that results when various parts of Z^(-1.1) and Z^(-7.7) are mixed before (1/C) is added. The resulting parent fractal is a grossly oversized thing with a prominent 'fan' on the X-axis, with the handle facing west. Today's image is located in a bit of fractal decoration on the blade of this fan. The bailout in today's image is almost 4-thousand-million. I was working with different parameters when I noticed that the fan evaporates as the bailout is raised. This evaporation starts at the handle and proceeds toward the edge. I set today's bailout to the point where the area of today's image is just about ready to evaporate, and rendered the fractal with the inside set to 'bof61'. The resulting image is a cross between a conventional image and an evaporated one. I named the image "Not a Blank Screen" for the obvious reason. If you see a blank screen, you have not changed the imag(p3) parameter. Then I rated it at a 7, which is the minimum rating that I consider satisfactory. In comparison to yesterday's image, which takes nearly an eternity to finish, today's finishes in under one minute on the fast P2000 machine and about 5 minutes on the P200. The image is also available for viewing on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> but because of the unusual time of day, and the bug in the parameter file, it may be a few hours before it is posted there. So be patient. It was a bit too warm and muggy for perfection here at Fractal Central on Saturday, but the fractal cats didn't mind. When we returned late in the evening, we found Nicholas sleeping in the magazine rack and Cassie curled on the coffee table, both of them happy but hungry. Tomorrow's FOTD will be another good one, and it will appear in only 12 hours. Until then, take care, and save energy; shower with a fractal.
