ABSTRACT:
A fragment program may configure a fragment shader to compute a destination position for a fragment, where the destination position is independent of a position computed for the fragment during rasterization of a primitive. The destination position may be computed based on fragment parameters such as color, depth, and transparency. A raster operation unit writes processed fragment data to the destination position. Furthermore, the fragment program may configure the fragment shader to compute a per-fragment stencil operation for use by the raster operation unit during stencil buffering.
