摘要
3DGIS、 3DGIS的可视化及把可视化模型作为交互操作的对象 ,是当前GIS的一个研究热点 .本文以三维城市模型为例 ,利用OpenGL拾取机制实现了三维场景中图形的属性信息的提取及相关的交互操作 .
With the development of computer technology and other related technology, currently, the trend of CIS development mostly includs web GIS. Open GIS. 3DGIS. integrated 3S ect.Of which, visualization of 3D Model, and make it as unit when querying and searching between graphic data and perproty data of spetial object has been the internal and abroad hotspot. In this pape, 3D Urban Model is given as examples. The inter_operation is realized in 3D scene by OpenGL.
