月球探测器可视化仿真系统的开发

基于软件平台OpenGL和Visual C++,开发了基于轨道动力学规律的月球探测器在轨运行实时视景仿真系统,用以动态仿真探测器、地球、月球和太阳的时空关系,实时地计算和显示探测器空间位置的变化,并利用三维可视化技术完成逼真的三维图形图像信息的显示.讨论了仿真系统软件结构,主要模块的设计,开发过程中所遇到的主要问题及其解决方法.实际应用表明,该可视化仿真系统可帮助用户更加直观地了解探月飞行任务的进行情况. 

Design of a Moon Exploration Probe Simulation and Visualization System

Based on the OpenGL and Visual C software platform,and the theory of orbit dynamics,a moon exploration probe simulation and visualization system was developed,this system can dynamically simulate the space-time relationship between probe,earth and moon,calculate the probe position and attitude in real-time,3D visualization technology was used to display the 3D graphics vividly.The main module design methods and the software architecture was discussed here, some problems encountered in the development progress are also discussed.Practical use of the system shows that it can help users to understand moon exploration process better.
