Abstract
Graphics processing includes setting up a plurality of objects in a scene in virtual space, each object being defined by a set of vertices. A unique object identifier is assigned to each object and written to an ID buffer. Draw calls are issued to draw the objects associated with the object identifiers. Parameter values of the vertices are manipulated to output vertex parameter values. Primitives are set up from the vertices, each primitive being defined by one or more of the vertices. Each primitive belongs to one or more of the objects. Each primitive is rasterized at a plurality of pixels. Processing the pixels includes spatial or temporal anti-aliasing that utilizes the one or more object identifiers of the plurality of object identifiers. The pixels are processed for each rasterized primitive to generate an output frame.
