  • Binning flush in graphics data processing
    Patent number: 6657635
    Abstract: Methods and systems for optimizing graphics data processing employ various binning flush algorithms to optimize the utilization of binning memory in a graphics system. Binning flush algorithms provide for processing all geometry and commands binned up to the point the binning memory becomes unavailable, and storing and restoring all necessary intermediate data generated during the partial tile rendering.

  • Method for determining tiles in a computer display that are covered by a graphics primitive
    Patent number: 6437780
    Abstract: A geometry tiler identifies tiles on a computer's screen that are covered by a graphics primitive by use of edges of the graphics primitive. Precise identification of tiles of various types (such as edge tiles covered by a segment) eliminates identification of one or more tiles that are merely located adjacent to the graphics primitive, but are not touched by the graphics primitive. For example, the geometry tiler can identify each of three types of tiles: vertex tiles, edge tiles and interior tiles.
