Hello, The focus of the CGAL Project is computational geometry, and we use boost wherever it makes sense. We are mentoring organization at the GSoC 2011, and we are looking for students who master boost and who are interested in replacing home-grown solutions by boost solutions in the CGAL library. We propose two topics: Replacing some Basic Non-Geometric Tools in CGAL by Boost/TR1/C++0x Functionality http://www.cgal.org/project_ideas.html#boostification Switching from CGAL::HalfedgeGraph to boost::PlanarEmbedding http://www.cgal.org/project_ideas.html#embeddedGraph Best regards, Andreas Fabri
