针对虚拟整形计划中三维人脸模型编辑问题，把人脸网格按照标定的特征点分布进行
分块处理。在各分块中分别采用不同的阈值进行调节，对于后续待操作区域，可以保持较高细节，减少简化程度，而对不需要进行操作的区域，可以设定较大的简化阈值，从而极大地减少了数据量。

A Feature Points-based Algorithm for 3d Face Mesh Siplification Abstract: To resolve the 3D Facial Model Edit problem in the field of virtual plastic projection, an algorithm which distributing the face mesh according to the marked feature points then blocked processing it was present. In term of every blocked part, different threshold is used to adjust it,for the next region which will be operated, keep more detail ,however, if the next region will be not operated,set biggish threshold to reduce the number of data.
