Zusammenfassung:A graphical display system of the present invention efficiently performs occlusion culling based on frame-to-frame temporal coherency. The graphical display system utilizes a frame buffer and rendering logic. The rendering logic is configured to receive graphical objects that define an image frame. In response to receiving one of the objects, the rendering logic is configured to make a determination as to whether the one object is visible in a previous image frame that was previously rendered to the frame buffer. The rendering logic is further configured to render the one object to the frame buffer based on the determination.
