基于VRML的内燃机车三维仿真

VRML-based 3D Simulation of Internal-combustion Locomotive

将多媒体、因特网和虚拟现实(VR)三种技术结合起来建立机车仿真系统进行人员培训,有助于机车操作人员和机车检修人员快速掌握内燃机车的有关知识,保证内燃机车安全运行.本文简单介绍了VR和VRML(虚拟现实建模语言),说明了建立内燃机车三维仿真VRML模型的方法,即采用其它三维建模工具建立三维模型后导出为VRML模型;指出了建模过程中出现的问题,给出了解决措施,即灵活使用简化模型和详细模型,对导出的VRML模型再处理,使其具有更好的效果;最后给出了模型实例和应用情况.

Combining multimedia, Internet and VR （virtual reality） together to establish simulation system of locomotive for personnel training is helpful for locomotive drivers and overhaulers to grasp knowledge about internal - combustion locomotive in a short time, which will ensure locomotive＇s moving safety. In this paper, an introduction on VR and VRML （virtual reality modeling - combustion locomotive en. In the end, a model language ） is given, and the methods on creating VRML models of simulation system for internal are explained and problems that appeared during modeling are pointed out and solutions are givexample and application are provided.
