实时交互式三维脸部表情动画研究及其实现

Research on real-time interactively animating 3-D facial expression and its implementation

根据人脸的生理结构特点,使用分块造型技术进行脸部建模,提出了一个基于“脸型特征”和“五官特征”的参数化肌肉模型,通过模型上控制顶点的属性值来控制脸部形成不同的表情,并利用MAYA MEL语言实现了一个实时交互操作界面。这使得对脸部表情的研究更加方便、灵活,建模及其动画化也更加逼真、实用。

According to the physiological feature of human face, a face model with block modeling technique is created and a parame- terized muscle model based on face shapes and facial features is presented, which can form different facial expressions by setting attribute values of controlling vertexes. A real-time interactive programmed interface is programmed by MAYA MEL language, which improves the flexibility and convenience of the research on facial expressions, It makes face modeling and its animation more realistic and practicably.
