Abstract
Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU. The apparatus may configure a BVH structure including a plurality of levels and a plurality of nodes, the BVH structure being associated with geometry data for a plurality of primitives in a scene. The apparatus may also identify an amount of storage in a GMEM that is available for storing at least some of the plurality of nodes in the BVH structure. Further, the apparatus may allocate the BVH structure into a first BVH section including a plurality of first nodes and a second BVH section including a plurality of second nodes. The apparatus may also store first data associated with the plurality of first nodes in the GMEM and second data associated with the plurality of first nodes and the plurality of second nodes in a system memory.
