摘要
A method and apparatus are provided for tessellating patches of surfaces in a tile based three dimensional computer graphics rendering system. For each tile in an image a per tile list of primitive indices is derived for tessellated primitives which make up a patch. Hidden surface removal is then performed on the patch and any domain points which remain after hidden surface removal are derived. The primitives are then shaded for display.
