Abstract

Abstract: A parametric surface fitting method based is presented on NURBS, which enables scattered points to be used for interpolation and approximation and then to generate smooth surfaces with the least square method. The algorithms and relevant software derived and developed are successfully applied in automotive body outer surface design. The method ensures the calculation stability and smooth surface quality.

Key words: Approximation, Fitting surface, Interpolation, NURBS, Scattered data
