摘　　要：随着计算机软、硬件技术的迅速发展,利用三维视景仿真技术动态描述列车运行仿真过程成为一个新的发展方向。简要介绍了三维视景技术在地铁列车运行仿真系统中的应用情况,以北京地铁一号线为例,分析了地铁三维视景模型的构成,研究了在PC机上利用Creator建立地铁三维模型的主要过程,详细分析了建模过程中的难点问题及相应的解决方法,最后介绍了适合地铁车站三维模型的简化方法。With the fast development of computer hardware and software, it is becoming a new developing aspect to illustrate the simulation process of trains operation by three-dimension visual technology. The status of subway operation simulation system with three-dimension visual technology has been introduced. Taking example for Beijing Subway Line 1, the composing of subway three-dimension visual models has been analyzed. It researched the main modeling process of subway three-dimension visual system a method to simplify the subway station model.. Also it analyzed difficulties through the modeling process and resolvents to the difficulties.
