摘　　要：研究探空火箭可视化问题,为帮助科研人员理解探空火箭任务中获取的抽象数据,直观地了解火箭的飞行状况,将探空火箭任务进行可视化具有重要意义。根据虚拟现实和可视化技术,使用3DSMAX创建火箭模型,可视化表达三维地球、弹道数据和姿态数据,解决因Direct3D世界坐标系为左手坐标系而带来的坐标转换难题,实现了探空火箭任务的可视化仿真。仿真结果表明,该设计在回放火箭发射场景和分析探空火箭任务方面具有较高的可靠性和准确性。In order to assist engineers understand the abstract data acquired from the sounding rocket task and know about the flight situation, it is significant to visualize the task. According to virtual reality and visualization technology, we modeled rocket by 3DSMAX, expressed three -dimensional earth, ballistic trajectory data and atti- tude data in directly, solved the problems of coordinate transformation caused by Direct3D＇s world coordinate and im- plemented the visual simulation of sounding rocket task. The simulation results show that the design has high reliabil- ity and accuracy in the playback of launch scene of rocket and analysis of the sounding rocket task situation.
