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.
No more traversal done in shaders, just one IMAGE_BVH_INTERSECT_RAY and then get the result without needing to push the current context to stack.
Additionally, the Traversal Engine can do a lot more parallel traversals in HW (for child nodes) than what is possible with shaders for a given CU count.
