CGAL 6.0.1 - Manual

The Computational Geometry Algorithms Library (CGAL) is a software project that provides easy access to efficient and reliable geometric algorithms in the form of a C++ library.

Package Overview

CGAL offers data structures and algorithms like triangulations, Voronoi diagrams, Polygons, Cell Complexes and Polyhedra, arrangements of curves, mesh generation, geometry processing, convex hull algorithms, to name just a few.

All these data structures and algorithms operate on geometric objects like points and segments, and perform geometric tests on them. These objects and predicates are regrouped in CGAL Kernels.

Finally, the Support Library offers geometric object generators and spatial sorting functions, as well as a matrix search framework and a solver for linear and quadratic programs. It further offers interfaces to third party software such as the GUI libraries Qt, and the Boost Graph Library.

The complete list of packages is available on the page Package Overview.
