"The most promising current parallel BVH construction approach is to use a so-called linear BVH (LBVH). The idea is to simplify the problem by first choosing the order in which the leaf nodes (each corresponding to one object) appear in the tree, and then generating the internal nodes in a way that respects this … See more One of the great things about LBVH is that once we have fixed the order of the leaf nodes, we can think of each internal node as just a linear range … See more The algorithm just described (Garanzha et al.) is surprisingly fast when there are millions of objects. The algorithm spends most of the execution … See more Now that we have a hierarchy of nodes in place, the only thing left to do is to assign a conservative bounding box for each of them.
