The toolkit offers functionality for approximate implicitization of 2D NURBS curves, 3D NURBS surfaces, surfaces defined by a 3D curve and a vector, and 3D point sets. The algebraic degree of the approximation is chosen by user, and can in most cases be chosen much lower than the theory of exact implicitization provides. The toolkit can either be licensed under the GNU GPL license for noncommercial use, or under a commercial software license for commercial use.
