Abstract
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 associated with a view frustum, where the BVH structure includes at least one first-level BVH including a plurality of first-level nodes and a plurality of second-level BVHs including a plurality of second-level nodes. The apparatus may also calculate whether the view frustum intersects with each first-level bounding box in the at least one first-level BVH. Further, the apparatus may calculate, for each first-level bounding box that the view frustum intersects, whether the view frustum intersects with each first-level child nod that is associated with each first-level bounding box. The apparatus may also output an indication of all of the first-level child nodes that the view frustum intersects for each of the set of first-level bounding boxes that the view frustum intersects.
