1. A method for dispatching pixel information in a graphics processing pipeline, the method comprising: generating a first pixel comprising a plurality of samples based on a first portion of a graphics primitive received by a first thread; calculating a first value for the first pixel, wherein the first value is calculated only once for the first pixel; calculating a first set of values for the samples in the plurality of samples, wherein each value in the first set of values corresponds to a different sample in the plurality of samples and is calculated only once for the corresponding sample; combining the first value with each value in the first set of values to create a second set of values; and creating two or more dispatch messages to store the second set of values in a set of output registers.
