摘要
IDL(Interactive Data Language,交互式数据语言)是进行二维及三维数据可视化显示、分析及应用开发的理想工具。详细介绍了IDL语言的特点,并以三峡永久船闸为例,阐述了基于IDL的三维建模方法,利用IDL图形对象提供的接口,建立模型对象与数据库的连接,实现数据的交互式可视化查询以及查询结果的可视化显示,对数据的可视化查询分析做了初步尝试。
IDL （ Interactive Data Language） is an ideal software using for visual analysis of 2D and 3D data . This paper introduced the characteristics of IDL in detail, as an example of three gorges permanent ship gate, presented the method of 3D modeling , Using the property of graphic object, constructing the connection be- tween the model objects and property database, It realizes the interactive visualization search of Model data and the visualization display of research result data.
