CGAL, the Computational Geometry Algorithms Library, is a large C++ library of geometric data structures and algorithms such as Delaunay triangulations, mesh generation, Boolean operations on polygons, and various geometry processing algorithms. CGAL is used in various areas: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, and numerical methods. License: Q Public License (QPL) Changes:
An important change from CGAL 3.3 to 3.4 is the switch to CMake for the installation. Besides improvements to existing packages, this release offers the following new algorithms and data structures: Polynomial (provides multi-variate polynomials), Modular Arithmetic (provides arithmetic over finite fields), 3D Spherical Geometry Kernel (provides functionalities on spheres, circles, circular arcs, and line segments in 3D), CGAL and the Qt4 GraphicsView (many 2D objects can be rendered in a QGraphicsView).
