Dynamic stereoscopic rendering method and processor

A processor comprising:

• an input module for receiving an input from at least a first virtual camera and a second virtual camera arranged to obtain at least a first view and a second view of a computer-generated scene, wherein the first virtual camera and the second virtual camera are positioned within the computer-generated scene so as to represent an interocular distance associated with the viewer;
• a target region identification module arranged to identify at least one target region of the computer-generated scene, the at least one target region being associated with a gaze direction of a viewer;
• a generation module for generating a first computer-generated representation representative of the first view based on the input from the first virtual camera and a second computer-generated representation of the second view based on the input from the second virtual camera, the first computer-generated representation and the second computer-generated representation comprising a plurality of rays which intersect with objects of the scene, wherein generating the first computer-generated representation and second computer-generated representation comprises:
• increasing the number of rays in the first view and the second view, arranged to intersect with objects in the target region of the computer-generated scene;
• and
• decreasing the number of rays in the first view and the second view arranged to intersect with objects outside the target region of the computer-generated scene;
• a relationship determination module for determining a relationship between at least one ray of the first computer-generated representation and at least one ray of the second computer-generated representation;
• a grouping module arranged to group at least one ray of the first computer-generated representation and the at least one ray of the second computer-generated representation based on the relationship, to form a group of rays;
• a processing module arranged to process one or more of the group of rays, substantially simultaneously to produce a first rendered view and a second rendered view of the computer-generated scene, wherein the first rendered view and the second rendered view are rendered using a first rendering technique in the target region and a second rendering technique outside the target region;
• and
• an output module arranged to output the first rendered view and the second rendered view to one or more display devices.

A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to:

• identify at least one target region of a computer-generated scene, the at least one target region being associated with data relating to a gaze direction of a viewer;
• generate at least a first computer-generated representation and a second computer-generated representation, where the first computer-generated representation represents a first view of the computer-generated scene obtained from a first virtual camera and the second computer-generated representation represents a second view of the computer-generated scene obtained from a second virtual camera, and each of the first computer-generated representation and the second computer-generated representation comprises a plurality of rays which intersect with objects of the computer-generated scene, wherein the first virtual camera and the second virtual camera are positioned within the computer-generated scene so as to represent an interocular distance associated with the viewer, and wherein generating at least the first representation and the second representation comprises:
• increasing the number of rays in the first view and the second view, arranged to intersect with objects in the target region of the computer-generated scene;
• and
• decreasing the number of rays in the first view and the second view arranged to intersect with objects outside the target region of the computer-generated scene;
• determine a relationship between at least one ray of the first computer-generated representation and at least one ray of the computer-generated second representation;
• group the at least one ray of the first computer-generated representation and the at least one ray of the second computer-generated representation based on the relationship, to form a group of substantially similar rays;
• process one or more of the group of substantially similar rays, substantially simultaneously to produce a first rendered view and a second rendered view of the computer-generated scene, wherein the first rendered view and the second rendered view are rendered using a first rendering technique in the target region and a second rendering technique outside the target region;
• and
• output the first rendered view and the second rendered view to one or more display devices.
