摘　　要：实时视景仿真中准确描述实体的姿态十分重要,欧拉角就是一种描述实体姿态的有效方法,它广泛应用于各种系统,出于对各自问题解决的需要,不同系统对于欧拉角的描述不尽相同。实时视景仿真Vega Prime软件即采用欧拉角HPR来描述仿真实体的姿态,从欧拉角HPR的含义、如何将实体的姿态调整为给定姿态(h,p,r)和欧拉角HPR的求取等三个方面进行了深入研究,最后以实例的形式分析了欧拉角的求取过程和求取方法。It＇s very very important to describe objectg postures exactly in real time scene simulation. Euler angle is an available method of describing object postures and has been applied to multifarious systems. However, the different systems need different description methods of Euler angles. The software of real time scene simulation Vega Prime adopts HPR of Euler angles to describe object postures. This paper research contents include the following three pans： the meanings of Euler angle HPR, how to adjust object postures to the known HPR and Euler angle HPR＇s solution. In the end, this paper analyses HPR＇s solution processes and methods from the example.
