Ray Tracing, Bounding Volume Hierarchy, Bvh, Axis Aligned, Tetrahedron Octahedron.
algorithm used for BVH traversal by NVIDIA OptiX and Intel Embree If we take a closer look at it, we can see pretty quickly that it is very easy to extend this to a Ray-AABO test. Like in the Ray-AABT test, we achieve this by using the fourth w-component of the ray and plane vectors to compute the
