Abstract

A computer-implemented method of performing intersection testing in a ray tracing system performs intersection testing for each of a plurality of rays against nodes of a hierarchical acceleration structure. The intersection testing for each of the rays comprises, in response to identifying, in a memory, an indication of a re-entry point associated with a ray identifier that is associated with the ray, fetching from the memory the indication of the re-entry point that is associated with the ray identifier, the re-entry point being a node of the hierarchical acceleration structure for which an intersection has been identified for a previously tested ray associated with the ray identifier. The intersection testing for each of the rays further comprises performing intersection testing of the ray against a set of nodes of the hierarchical acceleration structure starting from the re-entry point.
