CGAL
Computational Geometry Algorithms Library

The goal of the CGAL Open Source Project is to provide easy access to efficient and reliable geometric algorithms in the form of a C++ library. CGAL is used in various areas needing geometric computation, such as: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, mesh generation, numerical methods...

The CGAL Project uses Web 3.14 technology to make CGAL users more productive, and this far beyond just getting the programming job done.

Tag Cloud

Simply forget wading through the lengthy CGAL Package Overview, but simply have a look at the CGAL tag cloud. It reflects 10 years of user access patterns, and features the 50 pages looked up by 86.2% of our visitors.

Social Networks

Websites without Facebook's "Like" or Google's "+1" button will end up with a Google page rank of zero.

Starting from today, you can recommend CGAL from plenty of social networks.

In the next release we will roll out the "Like" button to every chapter of the CGAL User and Reference Manual. You will see who else likes "Algebraic Foundations".

Internet Relay Chat, Skype Screensharing

The CGAL Project enters a new era. So far you could only reach us via the cgal-discuss mailing list.

In the next days we will open the CGAL IRC channel. Additionally, you will see the skype online status of the CGAL developers listed on the Project Members page. Speak to them directly when you hit a bug, and even show them the stacktrace in Visual Sudio using skype screensharing.

Amazon

You are a Fortran programmer and you find that Barne Stroustroup's book on C++ has too many pages? You are not alone.

The CGAL Project has teamed up with Amazon and worked out the Listmania list of Must Have Books for Mastering CGAL.

Ebay

You have a commercial license for the CGAL Range and Segment Tree package and you want to resell it, as it turned out that what you really need is an AABB tree?

The CGAL Project has teamed up with Ebay, to make it easier for you to sell components you no longer need.

Centre Pompidou

Most people only associate triangulations with the word "Delaunay".

The CGAL Project offers 10 Day Passes for the Museum of Modern Art in the Centre Pompidou in Paris, which will allow you to learn more about not only Sonia Delaunay, but also about Pablo Voronoi, and Vladimir Minkowski.

Parship

CGAL users are often nerds, make jokes about the curiously recursive template pattern, and have a hard time to make friends.

The CGAL Project teamed up with Parship in order to find the partner for your life.

Parship uses higher dimensional CGAL Voronoi diagrams to identify people with strong affinities.
