This paper presented a useful quick mesh simplification algorithm based on edge collapse for the special three-dimensional mesh model——human face.According to the distribution of feature points,this algorithm dealt with the face which segmented into several areas.It adjusted different areas through giving different values.Kept the details where requsted,while other areas were simplified in an large extent.When this method was applied,the data would be reduced and remained the high details of preparative operation in the virtual face lifting.This algorithm can keep the characteristics of the model also implement easily and execute on high speed.
