Summary:An apparatus, system, and method for clipping graphics primitives are described. In one embodiment, a graphics processing apparatus includes a clipping unit that is configured to produce and issue ni initial outputs based on execution of a set of clipping operations, wherein ni represents the number of the initial outputs that are issued by the clipping unit prior to context switching, and the initial outputs partially define a clipped graphics primitive. The graphics processing apparatus also includes a control unit connected to the clipping unit. The control unit is configured to preserve an initial execution state of the clipping unit in response to an initial command for context switching, wherein the initial execution state is preserved based on ni.
