摘要
A method for rendering static graphics in a mobile device in applications such as map applications. Panning increments are received for panning a previously rendered frame to a panned frame. A rendering region is then determined based on the panning increment. A candidate polygon is then clipped to create clipped polygons contained within the rendering region. The clipped polygons can then be rendered, and a portion of the previously rendered frame can be copied, to provide the panned frame.
