Abstract: A method of operating a graphics processor to perform ray tracing. The graphics processor includes a ray tracing circuit that can be messaged by the graphics processor's programmable execution unit during execution of a program to perform a respective traversal of the at least one ray tracing acceleration data structure to be traversed for that ray. The ray tracing circuit may need to stop a ray's traversal to return the ray's processing to the programmable execution unit before the ray's traversal is subsequently restarted. In that case, the ray's traversal is restarted from the beginning.
