摘　　要：虚拟人不仅具有形体,更重要的是具有自主行为(行走、跑步、避障等).文中主要对跑步运动进行仿真.在对跑步运动过程进行分析的基础上,将一个跑步周期划分成6个运动序列.每个运动序列都有一个关键状态.首先使用逆运动学方法求出关键状态,然后使用样条插值和四元数球状线性插值方法计算中间状态,完成跑步的过程.并且引入运动特征参量,通过交互式控制,使跑步运动的姿态多样化.Virtual humans should look like real human in form, but they should also have autonomy （walking, running, avoiding obstacles, etc. ）. In this paper, running of virtual human and its control methods are researched. Based on the analysis of humanrs running, one running cycle is divided into 6 motion sequences, each of which has one key state. In order to simulate the motion of running, several steps have been used. Firstly, the key frames are created by the methods of inverse kinematics. Then, the internal key frames are computed by the interpolation of spline curve and spherical linear. Moreover, by introducing motion characteristic parameters the postures of running are made diversely.
