Further, it is desirable that w ( x ) be not zero for any x of interest. We provide an algorithm that implements the indicator function of NURBS-shaped planar domains, tailored to the fast computation on huge point clouds, together with the corresponding Matlab code. A NURBS curve parameterized by u is represented as C u = i f i u p i , where the p i are control points that determine the shape of the curve, and the f i u are the rational basis functions, each nonzero on one knot span. Aside from introductory material, this book focuses exclusively on NURBS curves and surfaces.
