摘　　要：针对现有文献中较少研究和处理物体在三维地形上的运动仿真,其姿态依赖于当时所处位置的地形特征这一情况,讨论了三维路径的交互式定义、平滑控制和控制点换算、物体姿态计算和调整等需要解决的问题,给出了解决步骤和方法;在Java3D环境中给出了在整条路径上同时实现物体位置移动和姿态调整的简便手段和用法.仿真结果表明,在复杂地形上运动物体姿态的生成和表现会增加仿真的逼真性和实用性,在军事模拟演习、汽车驾驶训练和三维游戏等诸多领域有广泛的应用前景.Few researches and treating methods concerning motion simulation of object on 3D terrain can be found in available literatures. At the same time, the posture of the moving object is dependent on the terrain features of its location. Aimed at the above problems, the interactive definition of 3D route was discussed, and the corresponding solutions and algorithms for conversion of controlling points in smooth movement and adjustment of object posture were given. The simple and convenient technique to realize both position movement and posture adjustment of the object on the whole route was given in Java3D environment. The simulation results show that the generation and representation of the posture of the moving object on the complicated terrain will increase fidelity and practicality. The present methods can be widely applied in such fields as military exercise, driving training and 3D games.
