US Patent:

Filed:

Jul 3, 2008

Appl. No.:

12/167997

Inventors:

Cass W. Everitt - Heath TX, US
Steven E. Molnar - Chapel Hill NC, US

Assignee:

NVIDIA Corporation - Santa Clara CA

International Classification:

G06T 15/50

US Classification:

345426, 345611, 345612, 345613, 345614

Abstract:

A system and method for dynamically adjusting the pixel sampling rate during primitive shading can improve image quality or increase shading performance. Hybrid antialiasing is performed by selecting a number of shaded samples per pixel fragment. A combination of supersample and multisample antialiasing is used where a cluster of sub-pixel samples (multisamples) is processed for each pass through a fragment shader pipeline. The number of shader passes and multisamples in each cluster can be determined dynamically for each primitive based on rendering state.
