ABSTRACT:
A three-dimensional graphic display apparatus performs hidden surface removal and color blending. Particularly, the graphic display apparatus includes a configuration of a special purpose memory for graphics, thereby forming a configuration of a graphic display apparatus using the special purpose memory. The special purpose memory for graphics includes a memory cell holding intensity information (RGB) and window information about each pixel, an XY coordinate converter converting XY coordinates of a pixel to be written to a memory address, an intensity blending processor, and hidden-surface removal and window comparators, all of which are formed on the same chip.
