摘要
介绍了目前国内外3维数据模型的研究现状及几种比较常用的3维数据模型。在对各种3维数据模型分析概括的基础上,基于城市地下管网自身的特点,指出了采用CSG-BR混合模型对地下管网进行建模的可行性和优越性。
This paper introduced the development of 3D data model and some 3D data models which were used usually. According to the analysis of 3D data model, on the basis of the feature of the city underground pipe system, it put forward the feasibility and superiority of using CSG-BR model to model underground pipe system.
