ABSTRACT:
Systems and methods for producing anti-aliased images use a sub-pixel sample pattern set that includes two or more unique sub-pixel sample patterns that are complementary. The sub-pixel sample patterns are offset from each pixel center and used to produce images that are combined to produce the anti-aliased image. In addition to providing sub-pixel coverage information, the sub-pixel sample pattern sets may be used to produce sub-pixel shading information. Furthermore, the sub-pixel sample pattern sets may be used in single processor systems or in multiprocessor systems to produce anti-aliased images.
