Cost-effective raster operation with enhanced shared-edge sampling for 3D graphics gaming applications

Due to the progress of consumer electronics, 3D-Graphics system has become mobilizing and attractive. For 3D graphics gaming applications with high resolution in mobile devices, the cost-effective hardware is crucial and necessary. In order to efficiently render 2D graphics, the raster operation techniques are developed. Traditional anti-aliasing techniques using the grid-based or point-sharing of edge to do super-sampling are not regular and complex. This paper proposed a novel cost-effective strategy for the shared-edge sampling of the primitive in raster operation. No expensive sampling action is involved, and no irregular sampling point is produced in the entire process. Furthermore, the blending colors in the neighborhood of these edges adopt approximate, fast, and robust anti-aliasing according to a set of simple rules.
