A method and system for computing pixel parameters is disclosed. In one embodiment, the rasterizing of a geometric primitive comprising a plurality of vertices wherein each vertex comprises a respective color value, is performed by a rasterization module of a graphics pipeline. The rasterizing includes interpolating a respective color value for each pixel of the geometric primitive, wherein the respective color value is of a first bit width. The rasterizing also includes transforming the respective color value to a second bit width to produce a respective transformed color value for each pixel. Additionally, the rasterizing includes altering the respective transformed color value using a screen-location based dither table to produce a dithered transformed color value for each pixel. After the rasterizing, propagating the respective dithered transformed color value of each pixel to downstream modules of the graphics pipeline is performed. |
