Abstract :
An algorithm for reducing control points in NURBS surface skinning is proposed in this paper. We first give distance estimation between the input curves and the surface that has been removed a knot. Then we further reduce the control points in NURBS surface skinning within the given tolerance by utilizing the ldquoresidual distancerdquo. Furthermore, the algorithm is applied to simplify a NURBS surface by giving distance estimation between the original surface and the knot-removal surface. Experimental results demonstrate the usability and quality of the proposed algorithm.
