Abstract
One embodiment provides for a general-purpose graphics processor comprising a multisample antialiasing compression module to perform planar multi-sample anti-aliasing, the multisample antialiasing compression module to analyze color data for a set of sample locations of a first pixel; determine a first plane to allocate for the first pixel, wherein the first plane is a lowest order plane to be allocated for the first pixel; and merge a plane allocation for the first pixel with a plane allocation for a second pixel in response to a determination that the first plane is the lowest order plane to be allocated for the second pixel.
