We are pleased to announce release 2.1 of CGAL, the Computational 
Geometry Algorithms Library.
CGAL 2.1 is the first release to support the Windows platform.

Additions to release 2.0 include:
- Triangulations in 3D
- Alpha shapes
- Several algorithms on sets of points in 2D
- Support for compilers under Windows NT/98/95 (VC++, g++). 
- and more

The CGAL project is a collaborative effort to develop a robust, easy to
and efficient C++ software library of geometric data structures and 
algorithms. The CGAL library contains:
- Basic geometric primitives such as points, vectors, lines, 
  predicates such as for relative positions of points, and operations 
  such as intersections and distance calculation.
- A collection of standard data structures and geometric algorithms, 
  such as convex hull, (Delaunay) triangulation, planar map, polyhedron, 
  smallest enclosing sphere, and multidimensional query structures.
- Interfaces to other packages, e.g. for visualisation, and I/O, and 
  other support facilities.

documentation,  please visit the CGAL web page:
