【摘要】 基于城市建筑物三维可视化的研究背景,以COM接口为基础,设计了一套适合ArcObjects三维建模的数据采集方法。该方法的前提是建筑物可进行分割,建筑物由普通房屋、人字形房屋、尖顶房屋、圆柱形(包括椭圆柱)房屋、圆台形房屋、圆环房屋、棱台形房屋、以及截球(包括椭球和球)8类标准几何体组件构成。探讨这8类标准几何体组件的构建方法,以及建模过程中一些关键问题的解决方案。更多还原

【Abstract】 With the background of research on 3D CGIS and the visualization of ruban 3D building,a data selecting and processing method of 3D modeling using the ArcObjects are designed,which is based on the COM interface. The building is composed of eight kinds of models,that are,normal house,herringbone house,sharp house,column,circular,frustum of a cone,prism and hemisphere. The article discussed the constructing methods about the above eight kinds of models,and solution for the process of modeling is given.更多还原
