C++ library for computational geometry

CGAL (Computational Geometry Algorithms Library) makes the most important of the solutions and methods developed in computational geometry available to users in industry and academia in a C++ library. The goal is to provide easy access to useful, reliable geometric algorithms.

The CGAL library contains:

 - the Kernel with geometric primitives such as points, vectors, lines,
   predicates for testing things such as relative positions of points, and
   operations such as intersections and distance calculation.
 - the Basic Library which is a collection of standard data structures and
   geometric algorithms, such as convex hull in 2D/3D, (Delaunay)
   triangulation in 2D/3D, planar map, polyhedron, smallest enclosing circle,
   and multidimensional query structures.
 - the Support Library which offers interfaces to other packages, e.g., for
   visualisation, and I/O, and other support facilities.

This package contains the main library libCGAL.so as well as two support libraries libCGAL_Core.so (from the CORE project) and libCGAL_ImageIO.so (image I/O). The library libCGAL_Qt5.so used for visualization in demos can be found in the package libcgal-qt5-13.
