摘要： A graphics processing unit (GPU) efficiently performs 3-dimensional (3-D) clipping using processing units used for other graphics functions. The GPU includes first and second hardware units and at least one buffer. The first hardware unit performs 3-D clipping of primitives using a first processing unit used for a first graphics function, e.g., an ALU used for triangle setup, depth gradient setup, etc. The first hardware unit may perform 3-D clipping by (a) computing clip codes for each vertex of each primitive, (b) determining whether to pass, discard or clip each primitive based on the clip codes for all vertices of the primitive, and (c) clipping each primitive to be clipped against clipping planes. The second hardware unit computes attribute component values for new vertices resulting from the 3-D clipping, e.g., using an ALU used for attribute gradient setup, attribute interpolation, etc. The buffer(s) store intermediate results of the 3-D clipping.

An example method includes the following: generating, within a processing pipeline of a graphics processing unit (GPU), vertex coordinates for vertices of each primitive within an image geometry, wherein the vertex coordinates comprise a location and a perspective parameter for each one of the vertices, and wherein the image geometry represents a graphics image; identifying, within the processing pipeline of the GPU, visible primitives within the image geometry based upon the vertex coordinates; and, responsive to identifying the visible primitives, generating, within the processing pipeline of the GPU, vertex attributes only for the vertices of the visible primitives in order to determine surface properties of the graphics image.
