  • Method and apparatus for processing primitive data for potential display on a display device
    Patent number: 7158132
    Abstract: A method and apparatus for processing a primitive (for potential display as a part of a graphical image on a display device) cause attribute data to be received by a graphics processor as a function of whether the primitive is capable of being viewable in the graphical image on the display device. Before taking that action, however, the method and apparatus assemble the primitive as a function of its positional data, and then determine if the primitive is capable of being viewable in the graphical image on the display device.

  • Primitive culling apparatus and method
    Patent number: 6900818
    Abstract: A method and apparatus for processing a primitive for potential display on a display device (having a plurality of pixels) determines if the primitive intersects at least a predetermined number of pixel fragments on the display device. The predetermined number is no less than one. The method and apparatus then cull the primitive as a function of whether the primitive intersects at least the predetermined number of pixel fragments. If it is culled, the primitive is not raster processed (i.e., not subjected to raster processing, whether or not complete).
