Claim 16:
17. A computing device comprising one or more processors operable to perform a method for shading a group of pixels in a raster graphics pipeline, wherein the method comprises:
shading at least one first pilot pixel of the group of pixels under a first precision to obtain a first color value;
shading at least one second pilot pixel of the group of pixels under a second precision that is lower than the first precision to obtain a second color value;
calculating an error value representing a magnitude of a difference between the first color value and the second color value;
shading at least one other pixel of the group of pixels under the first precision if the error value exceeds an error threshold; and
shading the at least one other pixel under the second precision if the error value does not exceed the error threshold.
