I made this a few years back for a homework assignment. Raytracing for extra credit. And then I went and lost the code. Blah. So here it is, back from the dead.
I've got the volume data generated via FBOs. Something sick inside me wants to experiment with some sort of realtime 3D simulation. Fluid maybe? But not right now.
This one still has a long way to go through. First I'm storing the color data in the volume. I'd rather be storing potential values in the volume, and maybe preprocessed normalized gradients. Next I don't have any good controls to influence the Julia Fractal at the moment beyond editing the lua script. All in due time.
