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 nodes each including one or more primitives, and each of the primitives being associated with a primitive ID, a geometry ID, and a set of floating-point coordinates. The apparatus may also compress the primitive ID or the geometry ID for each of the primitives. Further, the apparatus may convert a binary representation of each of the floating-point coordinates into an integer value of each of the floating-point coordinates. The apparatus may also calculate a difference between the integer value of each of the set of floating-point coordinates for each of the plurality of primitives. The apparatus may also store the compressed primitive ID or the compressed geometry ID and the calculated difference.
