The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

Just released bc_crunch: a tiny (~700 LOC), C99 library for lossless BC1/BC4/BC3/BC5 compression.
One .c/.h pair, no deps, no malloc
GPU-ready output
Zigzag + delta + popcount/dictionary tricks
Tested
Perfect for games, procedural assets, streaming textures.

We've seen how to define and apply Monte Carlo integration, but there's a whole world of techniques for reducing variance.
Part five (thenumb.at/QMC) covers Quasi-Monte Carlo: negative correlation, stratified and adaptive sampling, and low-discrepancy sequences.
