摘　　要：在列车虚拟运行场景仿真系统中,场景的铺设工作至关重要。本文应用动态链表技术将场景模块连接起来,采用单元分割法将场景模块细分,在场景动态显示时,根据场景单元模块与观察点的距离判断选择其绘制与否。实验结果表明,应用以上方法生成的列车虚拟运行场景系统具有较好实时性和视觉效果。In the 3D- scene simulation system of train movement,the Scene Lay - down is the most important part. In this paper, we connect scene models with the Dynamic Chain, segment the scene models by the way of Cell Segmentation, and choose cell models according to Distance Judgment between the cell model and the observer. The result of this practice demonstrates that the system has better timeliness and visual effect after using these methods.
