Abstract: Real-time rendering of triangulated surfaces has attracted growing interest in the last few years. However, interactive visualization of very large scale grid digital elevation models is still a hard problem. The graphics load must be controlled by an adaptive surface triangulation and by taking advantage of different levels of detail. Furthermore, the management of the visible scene requires efficient access to the terrain database. We describe a all-in-one visualization system which integrates adaptive triangulation, dynamic scene management and spatial data handling. The triangulation model is based on the restricted quad-tree triangulation. Furthermore, we present new algorithms of the restricted quadtree triangulation. These include among others exact error approximation, progressive meshing, performance enhancements and spatial access.
