摘要
采用多面体组合建立人体模型，用三角函数拟合步行时的关节活动轨迹，设计Ｂｅｎｄ函数来实现关节体和部位体的转动控制，采用逐节调整转动角度的方法实现人体下半身的旋转坐标变换，整体进行移动坐标变换，生成了步行过程中的一幅幅三维人体活动模型图形，使之在连续播映时产生逼真的人体行走动画效果．
in this paper, polyhedrons are used in building human body models. Trigonometric functions are used for approaching the tracks of joints motions in walking. Functions such as bend are designed for controlling rotations of joints and links. In order to implement shifts below waist and of whole body, the method of adjusting the angle of rotation link by link is adopted. In this way, 3D human body motion images in walking are generated and when they are shown continuously, the realistic and vivid animation about human body walking is obtained.
