基于面分块的三维人脸模型的边界表示方法

针对人脸造型中脸部模型的存储与表示问题，对人脸的生理结构特征进行了分析，在人脸共性的基础上，提出了一种基于面分块的三维人脸模型，并用边界表示法给出了这种模型的数据结构。按器官组织将人脸分解，各部分可以单独处理，合并起来又能构成一张完整的人脸，这种方法有利于表情的模拟和脸部动作的构造。

A Boundary Representing Method of 3D Facial Model Based on Surface Subdivision

Aiming at how to represent and store a facial model in the field of human face modeling,the character of human being's face physilogical structure is analysed at first.Then considering the commonness of faces,a kind of model is presented based on surface subdivision of the human face,and the data structure is also given for this model based on houndary representing.According to the organizing of apparatus,face is decomposed to several parts which can be handled alone,and united to a whole face.The method is beneficial to the conformation of expression and facial actions.
