摘要
本文提出了以脸部组织学、解剖学和生物力学特点为基础的脸部肌肉和皮肤运动的动态模型 ,该模型以分层设计的规则逻辑网格构造脸部轮廓 ,以脸部动作编码系统的运动单元为依据建立分层仿真的组织模型 ,采用肌肉的动力和弹力性能及皮肤层的体保持力和位恢复力性能控制脸部组织运动 。
This paper presents a dynamic muscle and skin model based on the characteristics of facial anatomy,histology and biomechanics.In this model,facial outline facet is constructed with regular logical lattices which are designed in layers.Layered synthetic tissue model is created in accordance with the Action Unit (AU) of Facial Action Coding System (FACS).Facial tissue motion is controlled by muscle force,muscle spring force and volume preservation force and position restoration force of the skin layer and thus the facial expression animation is generated.
