摘要：This paper firstly introduces the frame system of digital city and the process of 3D city modeling, and discusses the method of CSG modeling of buildings. This method extracts CSG primitives according to building features, then makes geometric transformation and regular Boolean operation on these primitives to form 3D model of buildings. The process of modeling and inner topological relationship of buildings can be represented by this method. ? (2011) Trans Tech Publications.
