Abstract

AbstractA useful and simple algorithm is presented for interactively generating B‐spline interpolation curves and surfaces from B‐spline approximation solutions. 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.
