######################################################### This is a zoom into Doug Stewart's fractal 'Suspended,' which is derived from Jim Muth's FOTD 07-03-28. The color map is the rotated 'Sunfish' color map from David M Fisher with black added for the 'lake.' This image could be called 'Black Pearls on pseudopods in ChaosLand.' I was able to count about ten complete cycles through the color map in the image -- which is a range of iterations of about 10 x 512. This means that I was able to see pixels that had at least 5000 iterations of the mandelbrotmix4 formula. In actual point of fact I believe that the image has many more iterations per pixel on average because of the fact that the image took about 20 seconds to calculate one horizontal row of pixels that had no 'lake' pixels in it on my 400MHz Pentium II. My setting the maxiter= to 16000 lets the details at the edges of the 'lake' features be crisp. The 1280x1024 version of this image took more than 7 hours to calculate so if you calculate it I would recommend your using Fractint's "Disk" Video mode and letting it calculate while you do something else. Calculating the image at this high resolution allows the pixels in the chaotic areas to turn into an almost invisible 'pixel broth.' - Hal Lane ######################### # hallane@earthlink.net # ######################### START PARAMETER FILE======================================= Suspended_F070328E { ; Hal Lane 07-03-28 7:18:09 P400 ; 1280 x 1024. ; Fractint Version 20.04 Patchlevel 4 ; Zoom into Doug Stewart's fractal: ; 'Suspended,' a zoom into Jim Muth's ; FOTD 07-03-28.
