Abstract:
1. A method, comprising: receiving coverage data at a depth/stencil test module, wherein the coverage data includes two-dimensional (2D) raster coverage data output by a rasterization module that indicates which subsamples within a multi-sampled pattern are covered by a primitive; modifying the coverage data by the depth/stencil test module to generate modified coverage data, wherein the coverage data is modified by modifying values in the coverage data for any subsamples that fail a depth/stencil test; inputting the modified coverage data into a pixel shader; and performing one or more actions at the pixel shader, utilizing the modified coverage data, wherein the rasterization module, the depth/stencil test module, and the pixel shader are included in a rendering pipeline implemented by a graphics processing unit.
