Surface Fitting of Parametric Improvement Based on Original Points
During the fitting of parametric curves and surfaces, selecting the parameters based on original points is very important, because it will affect the result of the fitting. In this paper an improved method of fitting surfaces by improving the parameters is proposed, this method is based on original points to interpolate NURBS curves and surfaces, it uses uniform knot vector, which is not affected by the distribution of original points, and it can reduce the amount of computation and improve some phenomena, such as break points and encircle. The results show that using this method can get satisfying figures.
