Abstract
The present invention relates to a device and method for processing pixel rasterization in 3-Dimensional graphic engine. According to an embodiment of the present invention, a method of processing pixel rasterizaton in 3-Dimensional graphic engine comprises the steps of: receiving a plurality of fragment informations; verifying whether the coordinate of the fragment informations are adjacent to X axis or not; detecting depth values of old fragment; comparing the depth values of the old fragment; storing depth values of the newly inputted fragment after comparison; and storing color values, which are performed alpha blending, in a color cache. The apparatus for pixel rasterization processing in 3-Dimensional graphic engine includes a depth readout unit, a depth test unit, a depth entry unit, a color readout unit, an alpha blending unit, a color entry unit, a depth cache, a color cache and a frame memory.
