This is a speed-optimized version of the Icosahedron shader posted here: ( http://kineme.net/composition/gtoledo3/Icosahedron ).
What remains is basically the depth equation...licensed under GPL/LGPL.
Smooth, usable and impressive
Cool, glad it's working ok. I hope you got the dl link for more that I posted on list about :-) (just in case... https://www.box.com/s/0a39f9915ddd122c54cd )
This is a little better looking/accurate, but slower "fast" raytracer... at least compared to the stock fragmentarium raytracer.
