Webhierarchical algorithm. 2.2. Refitting Fast updates to BVHs for deformable models are generally obtained through refitting, which keeps the BVH topology while recomputing … Web9 de nov. de 1999 · This algorithm maintains the scene model in an octree, and a frame's Z-buffer as an image pyramid, which we call a Z-pyramid. The octree enables hierarchical culling of occluded regions of the scene, and the Z pyramid enables hierarchical Z-buffering of individual primitives and bounding volumes.
