Abstract
Techniques are described for processing graphics images with a graphics processing unit (GPU) using deferred vertex shading. 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.
