On the shape parameter and constrained modification of GB-spline curves. (English) Zbl 1135.68603

Summary: GB-spline curves can be considered as the generalization of B-spline curve incorporating a shape parameter into the polynomial basis functions. The geometric effect of the alteration of the shape parameter is discussed in this paper, including constrained shape control of the curve.
