About a year ago, the company I work for acquired a multi- million dollar digital imaging department and I set out to create the biggest fractal in the world (or at least the biggest one I have ever seen...) I wanted to be able to blow it up to 40" X 60" an not see any pixelation in. This meant a resolution of at least 150 dpi so after I found the portion of the Mandelbrot set I wanted to do, I started crunching a 8,000 X 10,907 pixel fractal. Using my own Home Grown software, I did it in parts, because this thing took over 400 hours to crunch on my 75 Mhz pentium. I couldn't tie up my PC for that long uninterrupted, so I made the program such that I could stop the crunching at any point, then pick it up later when I went to bed. I had no idea what the color palette for this monster was going to look like while I was crunching it. Therefore, rather than writing a file which contained color information (such as a GIF, TARGA, or JPEG) I wrote a file which contained iteration information. i.e. each pixel in the file was represented by the number of iterations required before the crunching loop bailed, or maximum iteration was reached. Max iteration BTW was 65,000. After the crunching was complete, I worked on the color palette. I wanted 24 bit color so the change in tones would be very smooth on the final print. The final Targa file (chose that because it was very simple to write with only a 18 byte header) was approximately 260 Megs. I named this image "Primordial Chaos because it seems to be surging with energy. Let me know what you think. I'd be glad to give anyone the software I wrote to create this if there is an interest for it. Here's a smaller (Still, big tho.., 1 Meg) version of it. E-mail me at: jamesrh@egtnet.com Jimi
