  • Polygon binning process for tile-based rendering
    Patent number: 6975318
    Abstract: Binning polygons in a three-dimensional graphics system includes constructing a first bounding box around a first-level polygon, the first bounding box including tiles that contain the first-level polygon, subdividing the first-level polygon into second-level polygons if the first bounding box exceeds a predetermined size, and constructing bounding boxes around each second-level polygon. The second bounding box includes fewer tiles than the first bounding box.
    Type: Grant
