A 3D escape time algorithm for the limit sets of Kleinian groups

Posted on 2017-09-20 13:43
An extension into 3D of the method described in the article of the previous post produces images such as the ones in this new gallery.

Here is a new article on a fast algorithm for drawing certain Kleinian group limit sets.
Here is an example made in Shadertoy:

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.
