基于四元数插值的虚拟人运动平滑过渡研究

在虚拟环境中，虚拟人的运动平滑对三维场景的真实度有关键作用．提出一种基于关键帧及四元数插值的三次Catmull—Rom样条算法，实现了虚拟人的平滑行走、跑走及运动过渡．实验结果显示，该方法与传统方法相比，计算量小且算法简单易实现．

Virtual Human Body Motion Transition Based on Quaternion

In the virtual environment, the smooth movement of virtual human is important to the third dimension of three-dimensioal scene. This paper advances an algorithm based on key frame and quaternion with Catmull-Rom,and achieves the virtual human＇s smooth running, walking and the smooth transition Simulation shows that this algorithm is superior to the traditional method in its small compute quantity and it is easy to realize.
