Enhanced anti-aliasing by varying sample patterns spatially and/or temporally

A computer-implemented method for generating samples of pixel, the method comprising:

• receiving a first set of X-Y coordinates associated with a first pixel of a first frame, the first set of X-Y coordinates including an X coordinate and a Y coordinate;
• generating a first index into a first sample pattern table that includes a first plurality of entries based on the first set of X-Y coordinates, wherein the first index references a first subset of entries included in the first plurality of entries;
• extracting the first subset of entries from the first sample pattern table;
• and
• generating a first sample at a first location within the first pixel on an indication from a first entry included in the first subset of entries.

A computing device, comprising:

• a graphics subsystem, including:
• a first sample pattern table that includes a first plurality of entries;
• and
• an index unit that:
• receives a first set of X-Y coordinates associated with a first pixel of a first frame, the first set of X-Y coordinates including an X coordinate and a Y coordinate;
• generates a first index into the first sample pattern table based on the first set of X-Y coordinates, wherein the first index references a first subset of entries included in the first plurality of entries, and
• extracts the first subset of entries from the first sample pattern table, and
• a rasterizer that generates a first sample at a first location within the first pixel on an indication from a first entry included in the first subset of entries.
