1. An apparatus comprising:
a first circuit to traverse rays through a graphics scene comprising a plurality of primitives; and
a second circuit coupled to the first circuit, the second circuit to:
compress a set of bounding boxes to generate a plurality of bounding box compression blocks, wherein delta compression is used to compress a first plurality of the bounding boxes in a first bounding box compression block, wherein the first plurality of bounding boxes are compressed to the first bounding box compression block in a sequence, and wherein the delta compression comprises determining one or more differences between values of a current bounding box and a prior bounding box compressed to the first bounding box compression block, and storing the one or more differences as a first residual value in the first bounding box compression block,
compress a set of indices to generate a plurality of index compression blocks, and
process the bounding box compression blocks and index compression blocks to generate acceleration data structures.
