Ray Tracing, Bounding Volume Hierarchy, Bvh, Axis Aligned, Tetrahedron Octahedron.
etc. Consequently, it is employed in the world’s most sophisticated ray tracers, like NVIDIA OptiX and Intel Embree. In all cases that I’m aware of, the BVH is built upon Axis-Aligned Bounding Boxes (AABBs) as bounding volumes. The reasoning behind this is the simplicity to build the hierarchy,
