I’m trying to prove some theoretical analysis on ray traversal performance. Found a line (116) in cycles/bvh/bvh_params.h /* fixed parameters */ BVHs are often used in ray tracing to eliminate potential intersection candidates within a scene by omitting geometric objects located in bounding volumes which are not intersected by the current ray. Additionally, as common performance optimization, when only closest intersection of the ray is of interest, as the ray tracing traversal algorithm is descending nodes, and multiple child nodes are intersecting the ray, traversal algorithm will consider the closer volume first, and if it finds int…
