WebFeb 1, 2013 · The method is an extension of the current state-of-the-art on GPU BVH construction, Treelet Restructuring Bounding Volume Hierarchy (TRBVH), and consists of optimizing an already existing tree by rearranging subsets of its nodes using a bottom-up agglomerative clustering approach. WebThe BVH and CollisionList objects are convenience wrappers that store the GPU memory pointers needed to access BVH nodes and report collisions. We set them up on the CPU …

Did you know?
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. Web“We thought that it would be wise to utilise all of that because in the games that use hardware acceleration, they use the GPU for BVH (bounding volume hierarchy) construction. So they put a lot of pressure on the GPU. We wanted to distribute that among the CPU and GPU.”
