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: https://nuclear.mutantstargoat.com/hg/rayfract
The GUI is created using my immediate mode widget toolkit: https://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.

That looks great. I wish my raytracer was that fast :-) And it sure is a lot easier to find the perfect starting values (x,y,z,w) on yours; I did trial and error (try a number and see if it gives an interesting result).

Well done!

@MrMcsoftware Thanks mate, feel free to use it in order to discover interesting parameter sets, the code is available in the video info box :)

@nuclearthelab Forgot to mention that a part of your video (around 1:53) looks similar to the area I raytraced in my Reap The Whirlwind video. Could be either a close starting seed or one of the symmetrical areas,

@nuclearthelab  Thanks... will do...

That's pretty fancy man, it wiggles just fine!
