REDUCING FALSE POSITIVE RAY TRAVERSAL USING POINT DEGENERATE CULLING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240095994 titled 'REDUCING FALSE POSITIVE RAY TRAVERSAL USING POINT DEGENERATE CULLING
Simplified Explanation
The patent application describes techniques for reducing false positive ray intersections in a ray tracing hardware accelerator for traversing a hierarchical acceleration structure. This is achieved by selectively performing a secondary higher precision intersection test for a bounding volume, identifying and culling bounding volumes that degenerate to a point, and parametrically clipping rays that exceed certain configured distance thresholds.

Original Abstract Submitted
techniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure with reduced false positive ray intersections are disclosed. the reduction of false positives may be based upon one or more of selectively performing a secondary higher precision intersection test for a bounding volume, identifying and culling bounding volumes that degenerate to a point, and parametrically clipping rays that exceed certain configured distance thresholds.
