Realtime GPU Quaternion Julia Raytracer in GLSL

This is a realtime julia quaternion fractal raytracer I wrote a couple of years back in GLSL (OpenGL).

The source code is available at my mercurial repository: http://nuclear.mutantstargoat.com/hg/rayfract The GUI is created using my immediate mode widget toolkit: http://nuclear.mutantstargoat.com/hg/imtk

There's also a WebGL port in my webgl hacks collection: http://nuclear.mutantstargoat.com/webgl

Captured running on a Geforce GTS 250 on GNU/Linux. Any jerkiness is purely due to the capture program (gtk-recordmydesktop). I'll probably try to recapture this on windows at some point, to see if fraps manages to do a better job at it. ... https://www.youtube.com/watch?v=yZt--S1eS6A
