Abstract
The shape of non-uniform rational B-spline (NURBS) based free-form surface is determined by its control polygon. Shape modification is usually achieved by either individually changing the position or adjusting the weights at each of the control points. This paper proposed a unified method for shape modification of NURBS surface. The method provides a mathematical relationship between changes in the weight and location of control points to positional adjustment of surface points.
