Abstract :
Presents an optimization algorithm about cubic NURBS based on internal k-order- derivative constraints, and according to reset those control points, node vectors and weights, we can extend the NURBS curves to one target point or more target points. And we also prove those methods´ effectiveness through some specific examples.
