This greedy mesher is blazingly fast. Written with Rust and Bevy, using clever bitwise operations we can generate chunk meshes, an average of 0.000195 per 32x32x32 mesh!!!
This mesher blows most culled meshers out of the water, and I want to teach you the "secrets" of how to implement this for own voxel engine.
There are 2 algorithms we'll explore:
Binary greedy meshing AND binary face culling.
