REDUCING FALSE POSITIVE RAY TRAVERSAL USING RAY CLIPPING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17946201 titled 'REDUCING FALSE POSITIVE RAY TRAVERSAL USING RAY CLIPPING
Simplified Explanation
The abstract describes techniques for reducing false positive ray intersections in a ray tracing hardware accelerator for traversing a hierarchical acceleration structure. This includes selectively performing secondary higher precision intersection tests, culling degenerate bounding volumes, and parametrically clipping rays that exceed 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.
