摘要：The paper presents an automatic approach for the generalisation of 3D building models with regard to the visualisation of urban landscapes. Simplified versions of such models are not only needed for level of detail structures in real-time rendering, but also for web-based 3D GIS and for the presentation on mobile computing devices. To yield more sophisticated building models compared to already known surface simplification algorithms from the field of computer vision, the presented solution is based on least squares adjustment theory combined with an elaborate set of surface classification and simplification operations. This concept allows for the integration of surface regularities into the building models which are important for visual impression. These regularities are stringently preserved over the course of the generalisation process
