Abstract
Instead of shading a triangle from the rasterizer as soon as it is known that there is a sample inside the triangle, in accordance with one embodiment, shading is delayed until the triangle beside it, called the neighboring triangle, is received. If there is a neighboring triangle facing the same way, with non-mutually exclusive coverage, meaning that it is not overlapping the same region, then the shader shades only once for the pair of triangles. That is, two separate fragments are merged and treated as one fragment. Specifically, the fragment that is over the pixel center is the one that is used and the other fragment is replaced by merging. The merger happens only over the extent of a pixel and more than one primitive is not shaded at a time. However, multiple merges within a 2×2 block of pixels are possible.
