摘要
在对已有的 3维地面模型进行分析的基础上 ,论述了 3维地面模型的各种数据结构 ,并着重以DEM矩形格网为例探讨了地面模型的构造方法 ,以及在此基础上的动态显示和交互操作等功能。
According to the analysis of the present 3D terrain model,this thesis discussed all kinds of data structures of 3D terrain model,and demonstrated architectural method of grid DEM mainly ,then,illustrated its functions of dynamic display and interactive operation,etc.At last,a particular example was given based on the structure.
