Abstract: When a programmable execution unit of a graphics processor is executing a graphics processing program to render a frame that represents a view of a scene using a ray tracing process, and the ray tracing process requires the determination of geometry that will be intersected by a ray, the programmable execution unit sends a message to a ray tracing acceleration data structure traversal circuit of the graphics processor, for the ray tracing acceleration data structure traversal circuit to perform a traversal of a ray tracing acceleration data structure for the scene to determine geometry for the scene that may be intersected by the ray. The ray tracing acceleration data structure traversal circuit then returns to the programmable execution unit an indication of geometry that may be intersected by the ray, and the programmable execution unit uses the indicated geometry to determine any geometry that is intersected by the ray.

Abstract: A method comprising the steps of generating a first representation and a second representation, where the first representation represents a first view of a computer-generated scene obtained from a first virtual camera and the second representation represents a second view of the computer-generated scene obtained from a second virtual camera. Each of the first and second representation comprises a plurality of rays which intersect with objects of the scene. A relationship is determined between a ray of the first representation and a ray of the second representation; which are grouped based on the relationship, to form a group of substantially similar rays. One or more of the groups of substantially similar rays are processed substantially simultaneously to produce a first a second rendered view of the computer-generated scene. The first the second rendered view are output to one or more display devices.

Abstract: A data processor renders a new frame of a sequence of frames by, for each one of a subset of set of a plurality of regions of the new frame, newly generating output data for data elements in the region in respect of the new frame using a ray tracing process, and by deriving output data for data elements in each remaining region of the set of a plurality of regions of the frame based on data generated previously in respect of a preceding frame.
