20130328884 | DIRECT OPENCL GRAPHICS RENDERING - A method and apparatus for rendering graphics is disclosed. An edge list and polygon list are generated from a polygon based model. Each polygon is handled in parallel. For each polygon, an active edge pair table is generated based on the polygon list and edge list. Active edge pairs are selected from the active edge table based on a minimum position on a predetermined axis. All active edge pairs that intersect a scan line are processed. The processing includes computing a color value for each pixel lying between points where each active edge pair intersects the scan line. The pixel is then rendered and the active edge table is updated. | 12-12-2013 |
