摘要：
Free-form surfaces can be produced by integral equations and polyharmonic functions. This method is useful for multidimensional interpolation, because scattered data can be used and offsurface normal points are not used. A smoothing method using integrated polyharmonic functions, which is useful for local smoothing, has been proposed. However, there are no smoothing methods suitable for these free-form surfaces produced by integral equations. This paper describes a smoothing method using a least-squares approximation for the free-form surface produced by integral equations. To investigate the effectiveness of this method, several numerical examples are given.
