Bounding interval hierarchy
A bounding interval hierarchy (BIH) is a partitioning data structure similar to that of bounding volume hierarchies or kd-trees. Bounding interval hierarchies can be used in high performance (or real-time) ray tracing and may be especially useful for dynamic scenes. The BIH was first presented under the name of … See more Bounding interval hierarchies (BIH) exhibit many of the properties of both bounding volume hierarchies (BVH) and kd-trees. Whereas the construction and storage of BIH is comparable to that of BVH, the traversal of BIH … See more Instead of using two planes per node to separate geometry, it is also possible to use any number of planes to create a n-ary BIH or use … See more • Axis-aligned bounding box • Bounding volume hierarchy • kd-tree See more Construction To construct any space partitioning structure some form of heuristic is commonly used. For this the surface area heuristic, … See more Numerical stability All operations during the hierarchy construction/sorting of the triangles are min/max-operations and comparisons.
