1. A method for generating an image, the method comprising: with a graphics processing unit: receiving geometry data representing a location and a motion of a primitive during a frame interval; within a graphics processing pipeline, generating a plurality of intermediate primitives from the geometry data, each intermediate primitive associated with a respective intermediate time within the frame interval; multisampling each of the intermediate primitives, thereby generating a plurality of multisampled data sets for a pixel, wherein each multisampled data set comprises a depth and a coverage for each one of a plurality of sample locations and a single shading value associated with all of the plurality of sample locations; and filtering the multisampled data sets for the pixel to determine a color value for the pixel.
