Abstract:
1. A computer-implemented method for generating a clip state associated with a plurality of vertices positioned relative to a plurality of clip planes, the method comprising: for each vertex in the plurality of vertices, generating a per-vertex clip state based on a position of the vertex relative to each of the plurality of clip planes; for each plane of the plurality of clip planes, generating a per-plane clip state based on the per-vertex clip state of each vertex in the plurality of vertices, wherein the per-plane clip state indicates that all of the vertices in the plurality of vertices are inside the clip plane, all of the vertices are outside the clip plane, or some of the vertices are outside the clip plane and some of the vertices are inside the clip plane; generating the clip state associated with the plurality of vertices based on the per-plane clip state of at least two of the plurality of clip planes; and updating a clip state machine associated with the plurality of vertices based on the clip state, wherein the clip state machine is accessible by one or more elements within a graphics processing pipeline to determine whether to process the plurality of vertices.
