This paper presented a deformation and edition algorithm based on 3D calculation for 3D craniofacial model.The algorithm iteratively calculated feature geometric parameters of face after each deform. When requirement was fitted,it broke and stored model; or else the algorithm kept going on until model deforms to satisfying result.In order to improve the technique of free-form deformation in flexibility of user interaction and modification,improved the algorithm of point constrained deformation. Experiments show that this approach is straightforward,interactive easily and can achieve good results.
