Abstract:
Apparatus, system, and method for clipping graphics primitives are described. In one embodiment, a graphics processing apparatus includes a clipping engine and an output unit connected to the clipping engine. The clipping engine is configured to clip an input graphics primitive with respect to a set of clipping planes to derive spatial attributes of new vertices. The output unit is configured to identify a subset of the new vertices that defines an output graphics primitive, and the output unit is configured to derive non-spatial attributes of the subset of the new vertices to produce the output graphics primitive.
