Realtime GLSL Pathtracing

What's This?

This is a realtime GLSL pathtracer running live in your browser. Notice the realistic reflections, refractions, caustics, and global illumination; this can only be accomplished using raytracing. Click and drag to move the camera around (moving objects is not yet supported; I may get around to it someday).

A lot of the magic that makes this realtime is that the scene is simplified. For example, the box ranges from -1 to 1. Such allows for static optimizations in the shader, as well as that the scene is fairly simple. I'm also cheating.
