As points are placed in the axes, the B-spline of specified order is drawn progressively. The package comprises of a graphical utility to place uniform B-spline control points and see how the B-spline is redrawn as control points or control point weights are adjusted, and functions to estimate B-splines with known knot vector, given a set of noisy data points either with known or unknown associated parameter values.Īs regards the interactive interface, the user is shown a figure window with axes in which to choose control points of a uniform B-spline.
