摘　　要：介绍了数字城市的框架体系和三维城市模型的建模过程,探讨了城市建筑物的CSG建模方法。该方法先根据建筑物的特征抽取CSG体素,然后将这些体素进行空间几何变换和正则布尔运算,形成建筑物的三维空间几何模型,进而表达建模过程和建筑物内部的空间拓扑关系。This paper introduces the frame system of digital city and the process of 3D city model, discusses CSG model method of buildings. The method abstractes CSG primitives according to buildings' features, then makes geometry transform and regular boolean operation on these Primitives to form 3D model of buildings. The process of modeling and inner topological relationship of the building can be expressed by this method.
