Abstract:
A method for rendering static labels in a mobile device in applications such as map applications. Panning increments are received for panning a previously rendered frame to a panned frame and a rendering region is defined based on the panning increments. Ones of the labels that overlap the region and that overlap with the panned frame by a threshold amount are determined. Geometry that overlaps the rendering region is rendered and a portion of the previously rendered frame is copied. The ones of the labels are rendered to provide the panned frame.
