摘要
真实感人脸动画是计算机图形学领域的一个研究热点,为了更逼真的仿真虚拟人眼部的表情动作,提出了一种基于机构学原理与肌肉模型的人眼运动及表情仿真方法。可将人眼眼皮的三维网格模型分为边界点和非边界点分别控制,对于边界点的运动采用机构模型实现,对于非边界点及眼部其余部分采用肌肉模型控制,仿真出不同的人眼运动及表情。同时给出了仿真运动的效果实例。采用上述方法可以得到逼真的人眼表情动作仿真动画,效果良好。
Realistic facial animation is a hotspot in computer graphics. In order to obtain a delicate simulation of eyes movements, an animation method based on the theory of mechanism and the muscle model is presented in this paper. The 3D grid model of the eyelids is divided into two parts, the border points and the non - border points. The border points are controlled by the mechanism model, the non - border points and the other parts of the eyes are controlled by the muscle model. Some simulation examples are proposed, and the results show that this method can well simulate the eyes movements and expressions.
