| Abstract: | In this paper,based on the interpolation theory of B-spline curves, we propose the recursive algorithm of disk B-spline curves. And based on this, for the data with error given by measuring, i. e. The measured data distributed in a set of areas because of the existence of error,we present an algorithm which interpolate them by disk B-spline curves. The disk B-spline curves we get have many good properties such as locality and continuity. At the end of this paper ,we present several numerical examples to show our algorithm to be feasible and effective. |
