Abstract:
A processor employs work items to manage traversal of an acceleration structure, such as a ray tracing structure, at a hardware traversal engine of a processing unit. The work items are structures having a relatively small memory footprint, where each work item is associated both with a ray and with a corresponding portion of the acceleration structure. The hardware traversal engine employs a work items to manage the traversal of the corresponding portion of the acceleration structure for the corresponding ray.
