Study on the control method of NURBS curve quality for computer aided industrial design

NURBS curve and surface modeling technology is an emerging technology, developed in the 1980s, has been widely used in the CAID and CG. In CAID software based on NURBS technology, the quality of curve directly affects the quality of surface, and the post-editing and modification of the surface. This paper is based on the CAID software platform, combined the basic theory of NURBS curves with practical experience, we conduct an in-depth study on the method of controlling the quality of the NURBS curves, and propose an implementation to improve the quality of the NURBS curves.
