1. An apparatus comprising:
execution circuitry coupled to non-transitory machine-readable storage medium that stores instructions, which when executed by the execution circuitry, are capable of performing:
generating ray direction data based on intersection tests of a plurality of rays with a hierarchical tree structure of bounding boxes, the hierarchical tree structure of bounding boxes to test intersection between the plurality of rays and objects enclosed by the hierarchical tree structure of bounding boxes; and
sorting the plurality of rays into a plurality of ray groups based on the ray direction data.
