As a result, BVH trees and traversal reduce tens of millions of calculations down to a handful of simple ray box intersections followed by 6 ray triangle intersections.
At the very bottom, once a ray finishes traveling through all the bounding volume branches, which is called BVH traversal, we end up with a small box of only 6 triangles.
Inside the RT cores are two sections, the BVH traversal section takes in all the coordinates of the boxes and the direction of the ray and executes BVH traversal in nanoseconds.
