Mandelbrot fractal

Friday, September 30, 2005 ★ 01:15 ★ Category Programming

I wrote a Java applet that shows a colored rendering of the Mandelbrot set. Color depends on the escape speed. I used a light color for the numbers that are in the set, unlike most other renderings. Oh, the progressive rendering is done the easy way: plotting blocks first, then drawing pixels with the exact values on top.

Sample close-up

You can view the applet here. Java 5 required, I couldn’t be bothered to download/compile using Java 1.4. Usage: left click to zoom in, right click to zoom out, middle click to increase the maximum number of iterations before the number of escape steps is assumed to be infinite. Of course you can also use the text entries at the top to fine-tune your view.
