Path Tracing

My path tracer uses 15 spectral bins, and utilizes the same tone mapping that Pete provided for the spectral project. It also uses Russian roulette to speed up the calculations. Maximum number of bounces was five.

None of these images are totally converged, I’m planning on having my poor overworked computer do a 10 or 15 thousand samples per pixel image over Christmas break, but until then, 3 thousand is the most I’ve got.

I also decided that the images are too dark, so I gamma corrected them and provide both versions. The gamma corrected is always the second image.

100 paths/pixel:

800 paths/pixel

3000 paths/pixel:

I also did a model with a large, spherical light above it, also presented in gamma corrected form

It has 200 paths/pixel (note how having the large light source makes for a only slightly blurry image even with so few paths):
