ABSTRACT:
Anti-aliased output based on a scene comprising a plurality of objects may be generated. In one embodiment, a number of samples for an anti-aliasing operation is determined. For each of the samples: each of the objects may be translated in space according to jitter values; the objects may be multiplied by a fractional alpha value for the respective sample; a fractional alpha value stored in a buffer may be modified by a transparency value for each transparent object; and the objects may be rendered to the buffer by blending the objects with existing contents of the buffer. The fractional alpha values may vary from sample to sample. In one embodiment, the plurality of objects comprises one or more opaque objects and one or more transparent objects. In one embodiment, the objects may be rendered directly to a screen buffer.
