桌面型虚拟现实系统场景优化问题研究

Research on the Optimizing the Scene of Desktop Virtual Reality System

桌面型虚拟现实系统的应用慢慢开始普及,特别是在网络上,有很多虚拟旅游、虚拟博物馆、虚拟学习环境,让人们在计算机前就能得到较为真实的直观感受。但是,虚拟现实场景的显示是由计算机的显卡和中央处理器实时运算产生的,对于小场景的虚拟现实问题不会很大,但对于大场景,如果不对虚拟场景模型进行优化处理,将大大影响其运行速度,降低虚拟现实场景的表现力。

The application of desktop virtual reality system is slowly began to spread,especially in the network,there are a lot of virtual tourism,virtual museum,virtual learning environment,these virtual scenes make people have more realistic feel in front of the computer.However,a virtual reality scene display is composed of a computer video card and CPU real-time operations,it is not a problem for small scene,but for large scene,it will greatly influence the operation speed if not optimize the the virtual scene model.
