虚拟实验室导览系统的关键技术研究

Study on Key Technology of Virtual Laboratory Navigation System

虚拟现实导览系统除了能实现实时交互、顺畅浏览外、还应俱备场景内空间对象的信息查询功能。探讨了采用VRML技术构建综合型虚拟实验的一般流程、空间对象的场景数据组织、空间网格对场景的分割方法以及浏览时的场景分割与优化。以综合型态虚拟实验室为例，实现了基于空间网格分割的信息双向查询，并给出了具体实现结果。

The virtual navigation system can not only realize a live─interact and convenient browse but also can query about the information in the domain. This paper discusses the methods of constructing a general virtual lab based on VRML， the data of the space subject， the methods of decollating spacial─grid─decollating as an example and draws a detailed conclusion.
