摘　　要：介绍基于航天飞行器仿真的三维动态演示系统的开发背景、意义以及系统的具体实现方法。介绍了开发所需要的建模软件MultiGenCreator和仿真软件Vega。并使用MultiGenCreator建立了三维模型(火箭、航天飞行器以及发射场、着陆场和地球);使用Vega创建了仿真的环境(包括载入三维模型、云层、雾和火焰等特殊效果)。最后在Windows2000下,采用VisualC++6.0平台,根据实际的导航模型产生的位置和姿态数据驱动航天飞行器模型,实时更新飞行场景,仿真飞行的整个过程,实现全过程的3D图形化显示。The paper introduces a 3D dynamic demostration system based on simulation of the aerocraft and the significance of development and the method of realization. It also introduces two softwares: MultiGen Creator and Vega .They are useful tools for establishing the demostration system.We create some 3D models (including rocket, aerocraft, launchport, landing port and the earth) with the MultiGen Creator. We also build a simulation environment(including importing 3D models,cloud,fog and flame)for the system with the Vega. Finally the system is implemented on Windows 2000 platform with Visual C++ 6.0 IDE environment.It demostrates the entire flying course of the aerocraft with 3D models and the 3D model of aerocraft is driven by the data of position and attitude of the GNC system.
