摘要
为了把虚拟现实技术应用到三维地理信息系统— 3DGIS软件中 ,本文在分析虚拟现实建模语言 (VirtualRealityModelingLanguage)数据结构的基础上 ,采用面向对象的方法创建VRML结构类 ,并借助OpenGL在 3DGIS软件开发中实现了VRML数据模型的读取和三维可视化 。
In order to apply the technology of virtual reality (VR) to three-dimensional geographic information systems (3DGIS), a construction class for the data model of Virtual Reality Modeling Language (VRML) was built by using object-oriented method based on the structural analysis of VRML data model. The retrieval and 3D visualization of the VRML data model were implemented in a 3DGIS development scheme with OpenGL. Some interactive operations,like browse routes replay,are also presented.
