An escape time algorithm for Kleinian group limit sets

Posted on 2017-02-01 18:33
Here is a new article on a fast algorithm for drawing certain Kleininan group limit sets.
Here is an example made in Shadertoy:

Topology movies

Here is a new page with a number of video's on the topic of topology..

A collection of virtual vases, created by inverse stereographic projection of different patterns on the spherical surface of the vase.
All the patterns where done in Ultrafractal, whereas the vases were created in Povray.

I have recently been making some short movies (with sound) and have collected them on this page.

Hybrid 3D fractals

Posted on 2013-03-14 23:22
The 3D fractals in this gallery, were produced as hybrids between the Mandelbox and Mandelbulb formulas. The method is to alternate n Mandelbox iterations with m Cube folding/Mandelbulb iterations.

Chaos : a new movie!

True 3D limit sets of Kleinian groups.

Posted on 2013-01-05 21:00
In this new gallery, there is a small collection of new images depicting true 3D limit sets of Kleinian groups. They were generated by three Moebius transformations with quaternion coefficients.
I have also published an article on the subject.

4D polychora and hyperbolic space

Posted on 2012-06-03 14:26
Two new galleries, one on a kaleidoscopic method on drawing 4D polychora, and another one on drawing tesselated hyperbolic space. For more information, see this article (in French).
