3DMAX是优秀的三维建模软件,IDL是出色的科学可视化语言,也是三维GIS开发的有力工具。文中以ASE格式的3DMAX文件为例,在分析ASE格式文件结构的基础上,提出了在IDL中读取和重建3DMAX三维模型的思路和算法,并用实验对这一算法进行了验证。实验表明,3DMAX和IDL的结合能很好地实现GIS数据的三维可视化。

3DMAX is excellent 3-dimention modeling software. IDL is an outstanding scientific visualization language and helpful tool for 3DGIS developing. In this article,the author takes ASE file as a case,analyzes file structure of ASE,then give ideas and algorithm to getting and displaying 3DMAX models in IDL. Finally,an experiment is given to verify the algorithm. The result shows that combining 3DMAX and IDL is a good way to realize 3D visualization of GIS data.
