Which sets do the triangles in the overlapping regions go into?


I'm still a bit confused on how exactly this works. If there exists a triangle that has portions in both bounding boxes, which one does it go into? Does it exist in both of them?


How would we determine these disjoint sets? By the primitives' center positions?


Is the BVH structure recreated from scratch every frame or is it modified based on triangles that change positions?


Would this be the same method of partitioning as the centroid partitioning explained in later slides?
