About

If you ended up here, you probably tried to access Fract and you know what it is. If you don't, Fract is a web based application for zooming into the Mandelbrot Set fractal. It has a few interesting features like fractional iterations, palette restart, anti-aliasing, customizable color schemes and zooming movies generation. The Mandelbrot Set is vast and infinite. Some of its regions are more interesting than others and Fract allows visitors to send a region to the voting booth where other visitors can rate its beauty. The images in the header of this website are generated by Fract, so is this zooming movie and this animation of associated Julia sets.

Status

Fract is not working at the moment. I tried to put it back on track but I unfortunately don't have the processing power required to do so. As long as I could host my website on my home DSL, I was able to run it on a fast workstation. I get a lot of traffic these days; I moved to shared hosting but there is no way I can get cheap plan for something as resource hungry as Fract.

Gallery

I understand the disappointment of all Fract fans. I spent a week or so to render a bunch of regions with a lot of iterations, lot of colors, and full sub-pixel antialiasing. When the high iteration count was changing color mapping too much, I kept the antialiased 1024 iteration version. You can enjoy those all images in the Fract static gallery. All images are in the public domain: I want you to reuse and redistribute them.

Source Code

The latest stable version is 0.5.19, it depends on Polypen 0.3.5 and a few other libraries available on Cliki. This the complete Web and REPL interface and is it not known to be easy to setup. If the only thing you want is to produce cute images and animations, most of the engine was factored out as Mini-Fract 0.5.1. This is a stand alone Common Lisp program; it should be easy to install.

I also implemented a Mandelbrot Set renderer in C for the Apress Fractal Contest. This implementation sacrifices a lot of eye candy in favor of speed. I call it Fast Fract 1.0.
