Zusammenfassung:Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may obtain an indication of a BVH structure including a plurality of nodes, wherein the BVH structure is associated with geometry data for a plurality of primitives in a scene, wherein each of the plurality of nodes is associated with one or more primitives, where a first level BVH includes a set of first nodes and a second level BVH includes a set of second nodes. The apparatus may also allocate information for a plurality of second nodes in the set of second nodes to at least one first node in the set of first nodes. Further, the apparatus may store the allocated information for the plurality of second nodes in the set of second nodes in the at least one first node in the set of first nodes.
