WebAug 13, 2024 · A bounding interval hierarchy (BIH) is a partitioning data structure similar to that of bounding volume hierarchies or kdtrees. Bounding interval hierarchies can be used in high performance (or realtime) ray tracing and may be especially useful for dynamic scenes. The BIH was first presented under WebNov 18, 2014 · They built BVH by two steps: the first step was in the above level, and all threads were used to build the sub-tree of BVH; the second step was that each thread constructed a sub-tree. The first step used the two different methods: GRID and SAH and the second step also used the two different methods: SAH and BIH (Bounding interval …
