description The disclosed techniques includes generating an input visibility stream for each tile of a frame, the input visibility stream indicating whether or not an input primitive is visible in each tile when rendered, and generating an output visibility stream for each tile of the frame, the output visibility stream indicating whether or not an output primitive is visible in each tile when rendered, wherein the output primitive is produced by tessellating the input primitive. In this way, based on the input visibility stream, tessellation may be skipped for entire input primitive that is not visible in the tile. Also, based on the output visibility stream, tessellation may be skipped for certain ones of the output primitives that are not visible in the tile, even if some of the input primitive is not visible.
