METHOD AND APPARATUS FOR RASTERIZATION

The application provides a method for rasterization. According to the method, a primitive may be divided, at a position where a color abruptly changes in the primitive, into a plurality of sub-primitives with continuously and gradually changing colors. Each of the sub-primitives is then rasterized. The present application further provides an apparatus for rasterizing an image. The apparatus may comprise a dividing module configured to divide a primitive at a position where a color abruptly changes into a plurality of sub-primitives with continuously gradually changing colors. Furthermore, the apparatus may comprise a rasterizing module configure to rasterize each of the sub-primitives. The application may improve the speed of the rasterization and the quality of the processed image.
