Strange Attractors

Julien C. Sprott


Professor of Physics, Julien Sprott studied strange attractors, their chaotic properties as well as their artistic value. Some core features (especially the Attractor Search) and equations available in Chaoscope were found in his book "Strange Attractors: Creating Patterns in Chaos". Software and QBasic source code can be downloaded here.

Tim Stilson


The first author's visit to this page back in 1995 initiated the Chaoscope project. Tim Stilson proved strange attractors could be rendered as solid objects in a very efficient way. The method (on which the Chaoscope solid rendering is based) is explained here. Make sure you visit his fabulous strange attractors gallery.

Paul Thiessen

Paul and his friend John Holder followed Tim Stilson's path and wrote a program that renders solid 3D strange attractors. Paul is also the creator of PovChem which renders complex molecules - including DNA - in 3D.

Scott Draves

Creator of the famous Flames, which are an extended version of the Iterated Functions System. A free software is available for download. The result is similar to what Chaoscope can produce with IFS in Light rendering, bearing in mind Flames were created more than ten years ago!


Created by Mark Townsend, Apophysis is the most popular Flames editor around, probably because its interface, although simple, allows the user to create astonishingly beautiful pictures. It is a freeware, its source code is published under GPL license.


XenoDream is an advanced IFS editor. It can use primitives instead of points for each component (called "holon" in XenoDream) and includes a complex lighting system. The pictures galleries are a must see. XenoDream is a software created by Garth Thornton and Virginia Sterling.

Paul Bourke

This web site is mainly dedicated to Computer Graphics, including a contribution on rendering Fractals, where Paul outlines a colouring method for strange attractors based on the "speed" and the direction of its orbit. The Light rendering is based on this technique.



The Chaos Hypertextbook


A very practical study of the Chaos theory. A must read for anyone who wishes to understand the mathematical aspect of any fractal software.

The Infinite Fractal Loop


The Fractal gallery web ring. More than 240 web sites listed.



The father of all fractal software. Multi-platform freeware, dozens of fractal sets and strange attractors, built-in script language and function evaluator, a huge online help which can be read as a fractal encyclopedia, and much more! Source code can be downloaded separately. Maximum respect to the Stone Soup Group.

Ultra Fractal


Grand-son of FractINT, shareware, adds features such as true-colour rendering, anti-aliasing, Photoshop-like layers, multi-threading and multi-project environment.

Iterations et Flarium24


Not just two but a set of fractal programs : Iterations, Flarium24, GrafZVision, Sterlingware, InkBlot... They all require a bit of practice before obtaining good results, but the time spent on Stephen Ferguson's programs is always rewarding. Software is available for download for a small subscription fee.


ChaosPro can be considered as a mix between FractINT for the various file formats compatibility (formula, colour palettes, etc.), Ultra Fractal for the formula compiler, Frode Gill's Quaternion Generator for the quaternion rendering and Iterations/Flarium24 for the complex rendering modes, to which it adds real time fractal modification and a nifty animation module. ChaosPro is a freeware created by Martin Pfingstl.
