ABSTRACT:
A system, method and computer program product are provided for two-sided stencil testing during graphics processing. Initially, primitives are received to be processed in a graphics processing pipeline. In use, it is then determined whether the graphics processing pipeline is operating with same-sided stencil testing enabled. If same-sided stencil testing is not enabled, the primitives are passed without same-sided stencil testing and two-sided stencil testing. If, on other hand, same-sided stencil testing is enabled, it is determined whether the graphics processing pipeline is operating with two-sided stencil testing enabled. If the two-sided stencil testing is enabled and the same-sided stencil testing is enabled, two-sided stencil testing is performed on the primitives. If, on the other hand, the two-sided stencil testing is disabled and the same-sided stencil testing is enabled, same-sided stencil testing is performed on the primitives.
