WIP 2D sampling

This is a small application for exploring different 2D sampling strategies. It is mostly exploratory and implementations here have not been optimized for performance. Currently Poisson Disk Sampling is doing a bunch of avoidable mallocs.

Currently implemented:

1. Uniform random sampling
2. Stratified sampling
3. Poisson Disk Sampling [Fast Poisson Disk Sampling in Arbitrary Dimensions, Bridson]

TODO

• Visualization: Allow switching between different samplings during runtime.
• Low discrepancy sequences
• Higher dimensional sampling
• Variants of sampling according to probability map

Compilation and dependencies

This is just a single file with dependencies for visualization. You can compile it by simply:

gcc sampling.c -o sampling -lglfw3 -lopengl32 -lglew32 -lnanovg

Dependency list:

• glfw
• glew
• nanovg
