Real-time rendering of large-scale vector maps over terrain surfaces requires displaying substantial numbers of polylines and polygons. Because a long latency in display and manipulation is fatal to maintaining presence in a virtual environment, a new method efficiently simplifies and renders such maps. This method consists of three steps. First, it simplifies the vector map while maintaining the map's topological consistency and preventing local conflicts such as intersections or self-intersections. Second, it generates view-dependent level-of-detail (LOD) models. Finally, it overlays the maps onto multiresolution terrain models through the stencil shadow volume algorithm and other techniques. Experiments demonstrated the method's efficiencies in real-time rendering of large-scale vector maps over various LOD terrain surfaces.
