Abstract
A method and apparatus for multisample dithering is provided. For the method of the present invention, a graphics pipeline generates a series of b-bit color sample values for each pixel that is to be processed. Each color sample is defined to include one or more omitted values. The omitted values allow the color sample values to have a range that exceeds the range that would normally be associated with the b-bits of each color sample value. The extended range of the color sample values allows the color sample values to be summed to exactly reconstruct all color values. At the same time, the values in the color samples are close to exact values. This means that constructed color values are close to their correct values.
