摘要：
A nonuniform rational B-spline (NURBS) surface fitting method with tight tolerance for wrap-around models is presented. Using the sectional design technique, two primary boundaries and some interior sectional curves are extracted. A base surface is constructed by skinning these curves. By means of a method of base surface parameterization, an accurate and smooth fitting surface is implemented. The practical example demonstrated the feasibility of the proposed method.
