Abstract:
A method of processing pixel rasterization in a three-dimensional (3D) rendering processor comprising the steps of:receiving an input of present fragment image information from an outside; primarily checking existence/nonexistence of previous fragment image information corresponding to an address of the inputted present fragment image information; immediately texture-mapping the present fragment image information if the previous fragment image information does not exist as a result of the primary checking, while texture-mapping the present fragment image information after determining a depth value of the present fragment image information if the previous fragment image information exists; determining a transparency value of the texture-mapped present fragment image information; secondarily checking existence/nonexistence of the previous fragment image information corresponding to the address of the present fragment image information; determining the depth value of the present fragment image information if the previous fragment image information exists as a result of the secondary checking; storing the determined depth value of the present fragment image information; and determining and storing a color value of the present fragment image information.
