1. An apparatus comprising: a substrate; and logic coupled to the substrate, wherein the logic is implemented in one or more of configurable storage or fixed-functionality hardware, the logic to, when executed by a processor: select an anti-aliasing mode for a vertex of a primitive based on a parameter associated with the vertex, wherein the parameter corresponds to sample density, and wherein the sample density is higher for a vertex in a region of image quality importance and sparser for a vertex in a region where image quality is sacrificed, including vertices in motion blurred regions; retrieve sample offset data from a lookup table based on the parameter; generate a coverage mask based on the selected anti-aliasing mode, wherein the coverage mask is to be a render target independent coverage mask; and shade one or more pixels corresponding to the vertex based on the coverage mask and the sample offset data, wherein the selected anti-aliasing mode is to vary across a plurality of vertices in the primitive.
