An Interactive Fairing Algorithm for B-spline Curve

This paper presents an interactive algorithm about the fairness of a B-spline curve.The basic idea is to give each control point a small perturbation to construct a fair curve.The perturbations of each control point can be obtained minimizing the energy function.The weights of control points are applied to adjust the perturbation.The B-spline curve may be globally faired,but also can be adjusted locally in order to fair interactively.
