Abstract
Techniques for performing ray tracing for a ray are provided. The techniques include, based on first traversal of a bounding volume hierarchy, identifying a first memory page that is classified as resident, obtaining a first portion of the bounding volume hierarchy associated with the first memory page, traversing the first portion of the bounding volume hierarchy according to a ray intersection test, based on second traversal of the bounding volume hierarchy, identifying a second memory page that is classified as valid and non-resident, and in response to the second memory page being classified as valid and non-resident, determining that a miss occurs for each node of the bounding volume hierarchy within the second memory page.
