REDUCING FALSE POSITIVE RAY TRAVERSAL IN A BOUNDING VOLUME HIERARCHY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240095993 titled 'REDUCING FALSE POSITIVE RAY TRAVERSAL IN A BOUNDING VOLUME HIERARCHY
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 may involve selectively performing higher precision intersection tests, culling degenerate bounding volumes, and clipping rays that exceed distance thresholds.
- Selectively performing a secondary higher precision intersection test for a bounding volume
- Identifying and culling bounding volumes that degenerate to a point
- Parametrically clipping rays that exceed certain configured distance thresholds
Potential Applications
This technology can be applied in various fields such as computer graphics, virtual reality, augmented reality, and simulation software where real-time ray tracing is utilized.
Problems Solved
1. False positive ray intersections in ray tracing hardware accelerators 2. Inefficient traversal of hierarchical acceleration structures
Benefits
1. Improved accuracy in ray tracing 2. Faster rendering speeds 3. Enhanced realism in graphics
Potential Commercial Applications

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.
