Abstract
A system, method, and computer program product are provided for rejecting small primitives. A three-dimensional (3D) primitive is received and a position within the primitive is identified. The primitive has a size that is less than a threshold value. Sub-pixel coverage information is read from a pixel sample map using the position. If the position coincides with a sub-pixel sample according to the sub-pixel coverage information, then the 3D primitive is processed. Otherwise, the 3D primitive is rejected.
