- PLOC BVH2 builder with Parallel Reinsertion and spatial pre-splits.
- CWBVH An eight-way compressed wide BVH8 builder. Each BVH Node is compressed so that it takes up only 80 bytes per node.
- Tools for dynamically updating and optimizing the BVH2. (Added in 0.3)
- CPU traversal for both BVH2 and CWBVH (SIMD traversal, intersecting 4 nodes at a time)
- For GPU traversal example, see the Tray Racing benchmark
OBVHS optionally uses rayon to parallelize building.
See Tray Racing.
