The CGAL Open Source Project is pleased to announce the Release 3.8 of CGAL, the Computational Geometry Algorithms Library.
Besides fixes to existing packages major features where added in the following packages.
o 3D Mesh Generation
This package now can handle sharp features: the 3D Mesh generation package now offers the possibility to get in the final mesh an accurate representation of 1-dimensional sharp features present in the description of the input domain.
o 2D and 3D Triangulations
Add a way to efficiently insert a range of points with information into a Delaunay and Regular triangulation.
o 3D Alpha Shapes
The new class Fixed_alpha_shape_3 provides a robust and faster way to compute one alpha shape (with a fixed value of alpha).

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 and Delaunay triangulations in 2D and 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 algorithms (2D Delaunay mesh generation and 3D surface mesh generation, surface mesh subdivision and parameterization),
- 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 streamlines),
- optimization algorithms (smallest enclosing sphere of points or spheres, smallest enclosing ellipsoid of points, principal component analysis),
- kinetic data structures
