Patent ID: 7432932

Claim:
A home video game system, for use with a television type monitor display device, comprising: a game program processing unit for executing at least a portion of a videographics program that includes instructions for drawing one or more polygons for constructing and displaying 3D graphic objects; a video RAM for providing video frame data to a display device; and a programmable special purpose hardware graphics processor unit connected to the game program processing unit for receiving information relating to one or more polygons for constructing and displaying 3D graphic objects, the special purpose hardware graphics processor programmed to process pixel data for subsequent transfer to said video RAM corresponding to one or more portions of polygon-based 3D objects to be displayed, wherein said special purpose hardware graphics processor unit performs high speed 3D spatial coordinate transformation computations utilizing a 3×3 transformation matrix for computing new x, y and z spatial coordinates of polygon graphics data points to enable displaying of rotated and/or scaled polygon-based 3D objects at high speed and performs writing of polygon pixel data to the video RAM.
