We distinguish two This book describes the algorithms and mathematical fundamentals of a widely used software package for data fitting with (tensor product) splines. In many applications where curve fitting is used, one would like to modify parts of the curve without affecting other We study fitting, i.e., the construction of NURBS curves and surfaces which fit a rather arbitrary set of geometric data, such as points and derivative vectors.
