Sample count image

Final render, 11 seconds. Same 4-64 sample count with Halton sampling. I just forgot to square root my sample standard deviation.

Initial attempt at adaptive sampling

First attempt at adaptive sampling from 4 to 64, still using Halton. 3 second render. I think Im doing something wrong because it looks about the same as the uniform sampling.

Halton sequence random sampling with 16 samples per pixel. Render time was 9 seconds but looks much better.

Uniform sampling with 16 samples per pixel. 7s render.
