| titleOfInvention | Early termination in bottom-up acceleration data structure refit |
| abstract | Apparatus and method for bottom-up BVH refit. For example, one embodiment of an apparatus comprises: a hierarchical acceleration data structure generator to construct an acceleration data structure comprising a plurality of hierarchically arranged nodes; traversal hardware logic to traverse one or more rays through the acceleration data structure; intersection hardware logic to determine intersections between the one or more rays and one or more primitives within the hierarchical acceleration data structure; a node unit comprising circuitry and/or logic to perform refit operations on nodes of the hierarchical acceleration data structure, the refit operations to adjust spatial dimensions of one or more of the nodes; and an early termination evaluator to determine whether to proceed with refit operations or to terminate refit operations for a current node based on refit data associated with one or more child nodes of the current node. |
