The CGAL Open Source Project is pleased to announce the Release 3.7
of CGAL, the Computational Geometry Algorithms Library.
CGAL-3.7 provides improvements and fixes to existing packages, and
for new compilers.
See http://www.cgal.org/releases.html for a complete list of changes.
The CGAL project is a collaborative effort to develop a robust,
easy-to-use, and efficient C++ software library of geometric data
structures and algorithms, like
- triangulations (2D constrained triangulations, Delaunay
2D and 3D, periodic Delaunay triangulations in 3D),
- Voronoi diagrams (for 2D and 3D points, 2D additively weighted
Voronoi diagrams, and segment Voronoi diagrams),
- Boolean operations on polygons and polyhedra,
- Regularized Boolean operations on polygons with curved arcs
- arrangements of curves,
- mesh generation (2D, 3D and surface mesh generations)
and processing (surface mesh subdivision and parametrization),
- alpha shapes (in 2D and 3D),
- convex hull algorithms (in 2D, 3D and dD),
- operations on polygons (straight skeleton and offset polygon),
- search structures (kd trees for nearest neighbor search, and
range and segment trees),
- interpolation (natural neighbor interpolation and placement of
- optimization algorithms (smallest enclosing sphere of points or
spheres, smallest enclosing ellipsoid of points, principal
- kinetic data structures
