基于GIS的虚拟现实技术的应用

The Application of Virtual Reality Technology Based on GIS

GIS技术的快速发展和成熟为虚拟现实技术提供了一个良好的发展机遇,基于GIS的虚拟现实技术是虚拟现实技术最为重要的一个分支,它必将在未来得到越来越多的应用。基于GIS的虚拟现实技术的特点、核心技术,并以基于GIS的虚拟现实技术的一个应用领域———虚拟校园为例,具体介绍了基于GIS的虚拟校园系统的设计与实现过程中的相关知识,如数据的准备及处理、三维建模技术及搭建虚拟校园系统及功能的概述。

The rapid development and maturation of GIS technology has provided an excellent opportunity for the development of virtual reality technology. Virtual reality technology based on GIS is the most important branch of virtual reality technology, and it will have more and more application in the future. The paper mainly introduces the characteristics of virtual reality technology based on GIS, the core technology and gives an example of its application in a single virtual campus. Related knowledge in the design and implementation process of the virtual campus system based on GIS such as data preparation and processing, 3D modeling techniques, how to build a virtual campus system and their features are introduced.
