The difference between the data points and the B-spline approximation is used to modify the control vertices in order to generate a succession of B-spline approximations which converge rapidly to the interpolation solution. The intermediate B-spline approximations can be viewed interactively and the most appropriate solution selected for a particular application.enB-spline approximation and interpolationcurves and surfacesefficient iterative algorithm and control polygonEfficient algorithm for generating B-spline interpolation curves and surfaces from B-spline approximationsTechnical Report
