TRAVERSING MULTIPLE REGIONS OF A BOUNDING VOLUME HIERARCHY IN PARALLEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18089442 titled 'TRAVERSING MULTIPLE REGIONS OF A BOUNDING VOLUME HIERARCHY IN PARALLEL
The implementation described in the abstract involves traversing a bounding volume hierarchy for multiple rays simultaneously using multiple execution items. When one execution item finishes traversing the hierarchy for a ray, it moves on to traverse the hierarchy for another ray while another execution item starts traversing the hierarchy for the second ray. Side-effects are initiated in the order indicated by the bounding volume hierarchy.
- The implementation allows for concurrent traversal of a bounding volume hierarchy for multiple rays.
- Execution items are used to efficiently process the traversal of the hierarchy.
- Side-effects are initiated in a specific order based on the hierarchy.
- This approach optimizes the processing of ray tracing operations.
Potential Applications: - Computer graphics rendering - Virtual reality and augmented reality applications - Collision detection algorithms

Original Abstract Submitted
An implementation comprises traversing a bounding volume hierarchy for each ray of a plurality of rays concurrently using a plurality of execution items. In response to determining that a first execution item of the plurality of execution items is finished traversing the bounding volume hierarchy for a first ray of the plurality rays, the embodiment causes the first execution item to traverse the bounding volume hierarchy for a second ray of the plurality of rays while a second execution item of the plurality of execution items traverses the bounding volume hierarchy for the second ray. And the embodiment comprises initiating side-effects with the first and second execution items in an order indicated by the bounding volume hierarchy.
