A CPU-Side Voxel Raycaster using a beam-based acceleration. Instead of casting rays for each pixel, it scans the scene in 8x8 pixel blocks. The Beamcaster uses witness rays to skip empty space.

This is an experiment to generate a cubic voxel chunk mesh as efficiently as possible. This is insanely fast, meshing and drawing at around 650 FPS on my RTX 4090. The mesh generation itself is much ...
