2-D and 3-D combined rasterizer circuit for graphics accelerator

The invention is about improved rasterizing part which decides pixels to be displayed on screen for 2-d and 3-D graphics rendering circuit structure level. Traditional system can avoid either 2-D or 3-D acceleration because it only focuses on one type. Also, for 2-D graphics drawing, the function to reduce antialiasing effect in pixel is not implemented properly. The invention introduces 2-D and 3-D combined rasterizer in consideration of antialiasing. This combined rasterizer will optimize the 2-D and 3-D polygon drawing and reduce implementation cost because it shares resources.
