A bounding volume hierarchy (BVH) is a tree structure on a set of geometric objects. All geometric objects, which form the leaf nodes of the tree, are wrapped in bounding volumes. These nodes are then grouped as small sets and enclosed within larger bounding volumes. These, in turn, are also grouped and … See more The choice of bounding volume is determined by a trade-off between two objectives. On the one hand, we would like to use bounding volumes that have a very simple shape. Thus, we need only a few bytes to store them, … See more There are three primary categories of tree construction methods: top-down, bottom-up, and insertion methods. Top-down methods proceed by partitioning the input set into two (or more) subsets, bounding them in the chosen bounding volume, then keep … See more • Binary space partitioning, octree, k-d tree • R-tree, R+-tree, R*-tree and X-tree • M-tree See more 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 … See more • BVH in Javascript. • Dynamic BVH in C# • Intel Embree open source BVH library See more WebMar 6, 2024 · A bounding volume hierarchy ( BVH) is a tree structure on a set of geometric objects.
