WebA NURBS curve or non-rational B spline is a B-spline where the control points all have a weight. The weighting of the control points makes the curve rational. In NURBS, a point is computed by calculating a weighted sum of several control points. Here is a mathematical explanation of B-splines. Webor penetration between two non-convex NURBS surfaces.
