Abstract
A computer-enabled method for rendering a scene of objects representing physical objects includes projecting a first plurality of rays against a scene and aggregating a second plurality of rays that intersect a bounding volume, wherein the bounding volume encloses an object of the scene, and wherein the second plurality of rays is a portion of the first plurality of rays. The method further includes determining or computing intersections of the second plurality of aggregated rays with the object when the number of the second plurality of aggregated rays exceeds a predetermined value. The method also includes rendering the scene based on the determined intersections of the rays with the object. The second plurality of rays may be aggregated in a bounding volume aggregate data structure for processing.
