針對虛擬整形計劃中三維人臉模型編輯問題，把人臉網(wǎng)格按照標定的特征點分布進行
分塊處理。在各分塊中分別采用不同的閾值進行調(diào)節(jié)，對于后續(xù)待操作區(qū)域，可以保持較高細節(jié)，減少簡化程度，而對不需要進行操作的區(qū)域，可以設定較大的簡化閾值，從而極大地減少了數(shù)據(jù)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.
