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. The library is a module in the SINTEF  GoTools C++ library. See Products for more details, or go directly to <Description> <Source code (GPL license)> Share Published February 20, 2006
