WebAug 1, 2009 · Bounding volume hierarchies (BVH) have become a widely used alternative to kD-trees as the acceleration structure of choice in modern ray tracing systems. However, BVHs adapt poorly to non-uniformly tessellated scenes, which leads to increased ray shooting costs. ... Boulos, S., and Shirley, P. 2007. Ray Tracing Deformable Scenes … WebThe class does not know about shapes. Instead it operates on axis-aligned bounding boxes (AABBs) with user data pointers. The dynamic tree is a hierarchical AABB tree. Each internal node in the tree has two children. A leaf node is a single user AABB. The tree uses rotations to keep the tree balanced, even in the case of degenerate input. dewalt factory service dartmouth
