Abstract: When rendering a scene for output that includes a light source that could cast shadows in a graphics processing system, the world-space volume for the scene to be rendered is first partitioned into a plurality of sub-volumes, and then a set of geometry to be processed for the scene that could cast a shadow from a light source to be considered for the scene in the sub-volume is determined for any sub-volume that is lit by a light source.

The determined light source visibility parameter for an output sample is then used to modulate the effect of the light source at the output sample when rendering an output version of the output sample.

Abstract: A polygon Boolean operation and topology correction algorithm generates valid polygons despite polygon data containing self-intersecting polygons, overlapping polygons, polygons including a chain of holes, and/or polygons including complex intersections. A polygon Boolean operation and topology correction algorithm uses two variants of the Vatti algorithm along with a topology correction algorithm to address problematic areas within input data, such as the overlapping area shared between one or more polygons or a polygon having no area at all. Upon performing a variant of the Vatti algorithm to identify hot pixels within an arrangement of polygons, the polygon Boolean operation and topology correction algorithm runs a second variant of the Vatti algorithm to generate polygons within an integer coordinate system using snap-rounding.
