Fast Fractals

Are you surfing at slow speed? Take a look at RabbIT, the caching mutating webproxy

• Well I have now speeded the code up a few rounds (no more flaots speed sorta 35 % better) (the size is now 256 * 256 pixels (instead of 200* 200)) (961011)
• So I found another little optimization for this problem and implemented it (no bigger change) but will gain a few % in speed. (961018)
• Cleaned the code and made it more responsive. fixed the transparent middle to be black (much more beutiful:-). spedup a few more % =) (970527).
• Used my julia code to make a fast mandelbrot-generator that is what I consider to be fast enough.. (970614)

I have noticed several buggy jvm with this page

• Netscape(4.02, 4.03) and IE (3.02) under Windows NT crash immediatly when you look at this page. Theese applets dont even try to do anything mean. Every applet start two (2) threads each (one for the applet and one for the image-generation).
• IE under mac doesnt even work
• Netscape under Mac doesnt give the colors correctly. Seems Netscape/mac ignores my color-scheme.

• Fastjulia source
• FastMandel source
• FastJulia Math

Here is my speedy sierpinsky triangle. Real fast generation.
Thanx to Erik Agsjö for ideas. The Sierpiensky triangle can be made by a IFS but that takes time. This method produeces something more visually appealing and is much faster. Try to make it in asm and se how fast you can get it..

If you want to find more of java try this :

If you find your java code to slow try out SuperCede from asymetrix.
