高速铁路虚拟现实三维仿真场景优化方法研究

通过仿真高速铁路车站和电务设备的建模实例，提出了在铁路局域网等类似低带宽网络环境下通过运用模型优化、模型与图型的混用、灯光的设置、纹理贴图的使用、视角控制等方面的技术建立复杂实际设备时的具体思路和方法，并探讨了在大场景环境中采用的表现手法。为虚拟现实平台的搭建过程提供了清晰有效的建模思路及优化方法。

Optimization method of virtual reality 3D scene simulation for high-speed railway

Through modeling example of simulation station and electrical equipment for high-speed railway, the article proposed the specific ideals and methods for setting up practical and complex equipment by using the techniques of optimization model, mix model and graphics, lighting set, the use of texture mapping, viewpoint control in a limited bandwidth environment. The technique of expression used in the big environment was also discussed. It provided a clear and effective modeling idea and optimization method for the process of building the virtual reality platform.
