On the Shape Effect of a Control Point: Experimenting with NURBS Surfaces
In this paper we further the theoretical investigation, initiated in , on the shape effect of a single control point, measured in terms of the sign of Gaussian and mean curvatures of the underlying parametric surface. The so far obtained theoretical results are illustrated by experimenting with three typical NURBS surfaces, namely a cylinder, an ellipsoid and a torus.
