The BVH is an acceleration structure. It serves to reduce a pretty fundamental problem in ray tracing: the sheer cost of finding the nearest intersection of a ray and a scene consisting of (potentially) millions of polygons. The basic principle is easy to understand: if we have 64 polygons, we could split them into two … See more On my machine, it takes about 140 milliseconds to construct the 640 x 640 rays and intersect them with the 64 triangles.
