history
Project history and usage
CGAL, the Computational Geometry Algorithms Library, is a C++ library for reliable and efficient computational geometry algorithms.
Project history
The CGAL project started in 1996 as a consortium of seven sites in Europe and Israel, building on earlier internal geometry software such as PlaGeo, SpaGeo, the geometry part of LEDA, and INRIA Sophia-Antipolis's C++GAL.
Adoption history
The project moved from an academic-use license model to an open source license in November 2003 and published open source project rules and procedures in October 2005. The official repository notes that source tarballs, released twice a year, are the primary distribution vector.
How it is used
CGAL is used as a library rather than a single end-user CLI. Its packages cover kernels, convex hulls, triangulations, Voronoi diagrams, mesh generation, geometry processing, spatial searching, interpolation, and visualization support.
Why package nerds care
For package maintainers, CGAL matters because it is a large, template-heavy C++ geometry stack whose build and dependency behavior changed notably when version 5.0 became header-only.
Timeline
- 1996: CGAL started as a consortium project.
- 2003: CGAL adopted an open source license.
- 2005: CGAL published open source project rules and procedures.
- 5.0: CGAL became header-only according to the official repository README.
Related projects
- The official history cites PlaGeo, SpaGeo, LEDA, and C++GAL as predecessor or contributing internal projects.
