I decided to try out lighting models first. This is probably a bad idea, since I haven't yet bothered with simple things like more primitives and already my renders are taking forever. I have simple path tracing working, and am mostly convinced that it is correct. I'm still playing with different sampling schemes, and once I'm familiar enough I'll try out some bidirectional heuristics. Eventually I'd like to try Metropolis, but that's going to take a while.
All output files here have been created for a display gamma of 2.2, although I haven't set the proper PNG header for this (and sRGB space) on all of the files.

Playing with different randomized techniques for lighting. Right now
I'm playing with spherical area lights, randomly sampling the
That said, it still sucks.

First round of coding was extremely fruitful, thanks to the help from
James especially, since he just wrote a ray tracer for
class this term.|
Got simple reflections working, adaptive supersampling, spheres and planes, and used cheezy phong shading.
