Our main products are the individual data structures and algorithms of CGAL, the Computational Geometry Algorithms Library, as they can be found in the Package Overview. Whether you use CGAL under the commercial or the open source license terms, the software is identical, but the rights and obligations are different.
We also offer leda numbers as a drop in replacement for the arbitrary precision libraries GMP/Mpfr, for customers who do not want dependencies on software that is distributed under the LGPL open source license. The leda numbers package is not available under an open source license.
We finally offer a quad mesh generator, developed at RWTH in Germany. The quad mesher is not available under an open source license.
