虚拟环境中的虚拟观察者模型

Virtual Observer Model in Virtual Environment

分析了虚拟环境的特点和信息表示的方法，针对虚拟环境仿真中选取观察信息时存在的问题，提出了能有效辅助参与者获取虚拟环境中多维信息的虚拟观察者模型，讨论了模型的实现方式，并介绍了该模型在虚拟战场中的应用。

This paper analyses characteristics of virtual environment and information representation used in virtual environment. Aiming at problems of selecting information being observed in virtual environment, we propose virtual observer model, which can help people to acquire multi-dimension information of virtual environment, discuss the implementation of the model and apply it in virtual battlefield.
