Abstract: A processor for raytracing is provided, the processor being configured to: generate a bounding volume hierarchy, quantize at least one bounding box associated with the bounding volume hierarchy, dynamically allocate a number of quantization bits for at least one of x, y, and z dimensions of the at least one bounding box, wherein a variable number of quantization bits per dimension is used in the quantization.

Abstract: A processor for ray tracing is provided. The processor is configured to provide an acceleration structure including at least one junction node, obtain rays with associated detail base and detail attenuation parameters, and traverse the acceleration structure using the generated rays, wherein the junction node comprises: a junction factor, a pointer to a low level of detail acceleration structure, and a pointer to a high level of detail acceleration structure. The processor is configured to determine a junction entrance value based on the detail base parameter, the detail attenuation parameter, and a distance value, and to compare the junction entrance value to the junction factor to determine which level of detail acceleration structure to traverse.

Abstract: A graphics processing system and method for ray tracing traversal in a hierarchical acceleration structure utilizes a memory and processor. The processor evaluates nodes and ray intersections with child node bounding volumes, marks nodes for reevaluation, and stores thresholds related to child node intersections. The system returns to marked nodes when current node intersections exceed thresholds. Nodes are marked using one bit in the internal structure and stored as stack offsets. Thresholds are calculated using near and far intersection points. Child nodes exceeding thresholds are placed on a stack before returning to marked nodes. This approach enables efficient traversal path selection, reducing unnecessary checks and improving ray tracing performance in complex scenes.
