Abstract: In various examples, shader bindings may be recorded in a shader binding table that includes shader records. Geometry of a 3D scene may be instantiated using object instances, and each may be associated with a respective set of the shader records using a location identifier of the set of shader records in memory. The set of shader records may represent shader bindings for an object instance under various predefined conditions. One or more of these predefined conditions may be implicit in the way the shader records are arranged in memory (e.g., indexed by ray type, by sub-geometry, etc.). For example, a section selector value (e.g., a section index) may be computed to locate and select a shader record based at least in part on a result of a ray tracing query (e.g., what sub-geometry was hit, what ray type was traced, etc.).

Abstract: A system and method for constructing a bounding volume hierarchical structure are disclosed. The method includes defining a parent node for the bounding volume hierarchical structure, the parent node including a parent node bounding volume enclosing a plurality of objects. A first cost is computed for performing an object partition of the parent node bounding volume to produce a first plurality of child node bounding volumes, and a second cost is also computed for performing a spatial partitioning of the parent node bounding volume to produce a second plurality of child node bounding volumes. The bounding volume hierarchical structure is constructed employing the second plurality of child node bounding volumes produced from the spatial partitioning of the parent node bounding volume if the second cost is lower than the first cost.

Abstract: Approaches for addressing issues associated with processing workloads that exhibit high divergence in execution and data access are provided. A plurality of workload items to be processed at least partially in parallel may be identified. Coherence information associated with the plurality of workload items may be determined. The plurality of workload items may be enqueued in a segmented queue. The plurality of workload items may be sorted based at least on a similarity of the coherence information. The sorted plurality of workload items may be stored to the queue. Using a set of processing units, the workload items in the queue may be processed at least partially in parallel according to an order of the sorting.

The method includes defining a parent node for the bounding volume hierarchical structure, the parent node including a parent node bounding volume enclosing a plurality of objects. A first cost is computed for performing an object partition of the parent node bounding volume to produce a first plurality of child node bounding volumes, and a second cost is also computed for performing a spatial partitioning of the parent node bounding volume to produce a second plurality of child node bounding volumes. The bounding volume hierarchical structure is constructed employing the second plurality of child node bounding volumes produced from the spatial partitioning of the parent node bounding volume if the second cost is lower than the first cost.
