How To Install libcgal12 on Debian 9
Introduction
In this tutorial we learn how to install libcgal12
on Debian 9.
What is libcgal12
libcgal12 is:
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-qt5-12.
