The Computational Geometry Algorithms Library (CGAL) is a C++ library that aims to provide easy access to efficient and reliable algorithms in computational geometry.
The primary vector of distribution of CGAL are sources tarballs, released twice a year, announced on the web site of CGAL.
Getting Started with CGAL
Since version 5.0, CGAL is a header-only library, meaning that it is no longer needed to build CGAL libraries before it can be used.
Head over to the CGAL manual for usage guides and tutorials that will get you started smoothly.
See the file LICENSE.md.
CGAL Git Repository Layout
The Git repository of CGAL has a different layout from release tarballs. It
CMakeLists.txt file that serves as anchor for configuring and building programs,
and a set of subfolders, so called packages. Most packages
implement a data structure or an algorithm for CGAL (e.g.,
Triangulation_3); however some packages serve special needs:
Installation- meta-files and CMake-support
Maintenance- infrastructural support
GraphicsView- component libraries
Scripts- scripts to simplify developer's and user's work
Testsuite- infrastructure for testsuite
Documentation- infrastructure for CGAL's manual
STL_Extension- extensions to the standard template library
