| Abstract: | A weight-based optimal fairing algorithm for planar parametric cubic NURBS curves is presented. The purpose of this paper is to make the change of curvature of faired curves more gradual and its deviation from the initial curves smaller. It shows that it is simple and needs a small amount of calculation. |
