Abstract
Aspects presented herein relate to methods and devices for graphics processing including an apparatus, e.g., a GPU or CPU. The apparatus may configure a BVH structure including a plurality of nodes, the BVH structure being associated with geometry data for a plurality of primitives in a scene. The apparatus may also detect a set of child nodes for a current node of the plurality of nodes. Further, the apparatus may identify a first child node of the set of child nodes based on a node ID of the first child node. The apparatus may also calculate an offset between the node ID of the first child node and a node ID of each of the remaining child nodes in the set of child nodes. The apparatus may also store a representation of the node ID of each of the set of child nodes based on the calculated offset.
