System and method for accelerated ray-box intersection testing |
摘要 |
A method for performing a ray-box intersection test includes forming a span extending between a first plane-ray intersection point and a second plane-ray intersection point, and increasing the span by relocating to a new position at least one of the first and second plane-ray intersection points. A box intersection span is constructed using the increased span, and the box intersection span, which corresponds to a node in a hierarchical acceleration structure, is tested for intersection with the ray.
