WebA 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.

WebJun 15, 2024 · The concept of the TLAS (a.k.a. top level BVH) was introduced in article 5 and article 6. The idea is to build and traverse a BVH over BVHs, where each of those BVHs can have a 4×4 matrix transform, for translation, rotation, and scaling. Using the same BVH multiple times but with a different matrix enables instancing. china ergonomic car seat cushionsWebJun 15, 2024 · droettger February 2, 2024, 2:03pm 2.
