| Abstract: | A method to fairly fit the given data points with the least squares of the cubic B - spline curve and an algorithm for degree elevation of uniform B - spline curves are analyzed in this paper. For the numbers of section data varying in each section, the fair fitting method of bicubic B - spline surface is presented. A calculating example is also provided. |
