The Triangulation Template Library
The Triangulation Template Library (TTL) is a library for operations related to triangulations. TTL is not dependent on a specific data structure, but can be adapted to any type of triangulation defined by the user. Delaunay triangulation, add/remove nodes and search/traversing are examples of tools. The code is implemented in C++.

GoTools is the group name of many interdependent C++ software modules developed by the geometry group at SINTEF Digital, Department of Mathematics and Cybernetics. Starting around the year 2000, GoTools software has been developed for a range of different applications in many different projects. Most of the functionality is related to geometry, and in particular spline representations of geometry, see the highlights and overview of functionality. For more idetail, see GoTools manual.
GoTools is offered with the GNU Affero General Public License version 3. Alternatively, you can be released from the requirements of the license by purchasing a commercial license. Buying such a license is mandatory as soon as you develop commercial activities involving the GoTools library without disclosing the source code of your own applications.
