A system, method, and computer program product are provided for shading using a dynamic object-space grid. An object defined by triangle primitives in a three-dimensional (3D) space that is specific to the object is received and an object-space shading grid is defined for a first triangle primitive of the triangle primitives based on coordinates of the first triangle primitive in the 3D space. A shader program is executed by a processing pipeline to compute a shaded value at a point on the object-space shading grid for the first triangle primitive.

A system, method, and computer program product are provided for performing object-space shading. A primitive defined by vertices in three-dimensional (3D) space that is specific to an object defined by at least the primitive is received and a shading sample rate is computed for the primitive based on a screen-space derivative of coordinates of a pixel fragment transformed into the 3D space. A shader program is executed by a processing pipeline to compute shaded attributes for the primitive according to the computed shading sample rate.

A stereo viewpoint graphics processing subsystem and a method of sharing geometry data between stereo images in screen-space processing. One embodiment of the stereo viewpoint graphics processing subsystem configured to render a scene includes: (1) stereo frame buffers configured to contain respective pixel-wise rendered scene data for stereo images, and (2) a sharing decision circuit operable to determine when to share geometric data between the stereo frame buffers for carrying out screen-space effect processes to render the scene in the stereo images.

A shadow softening GPU and method. One embodiment of the GPU is configured to render a shadow cast by a surface occluding a light source and includes: (1) a fetching circuit operable to retrieve a depth value from a texture associated with the surface and a depth comparison result in a single fetch operation, and (2) a shadow softening circuit configured to respectively employ the depth comparison result and the depth value to identify the surface as a blocker and attenuate the light source for a pixel.
