摘　　要：重点介绍了三维实体的建模方法、场景驱动及视点变换技术。应用高级实时仿真功能,建立了适合高效运行的车辆、轨道等三维模型,并对场景的组织结构进行了优化。仿真结果表明,系统的图像生成速度迅速、稳定,满足视景仿真的实时性要求。How to improve the rendering speed in real-time simulation of the vehicle running on the track is discussed in this paper. The means of modeling 3D objects, scene driving and viewpoint translation are introduced especially. Adopting some advanced real-time simulation function, 3D models of vehicle, track, etc are created which are suitable for high-efficient simulation, and finally optimized the structure of the scene. The results show that the system renders the scene quickly and steadily and the effect can satisfy the real-time requirement in visual simulation.
