CGAL 2.3, Computational Geometry Algorithms Library

[hert at mpi-sb.mpg.de]

We are pleased to announce release 2.3 of CGAL, the Computational
Geometry Algorithms Library.

Major additions in this release include:

  o Realization of a new kernel concept that provides more flexibility
    while being completely compatable with the previous design
  o d-dimensional kernel, convex hull and Delaunay triangulations
  o Redesign of the halfedge data structure to provide better
    extensibility
  o Improvements and additions in 2d and 3d triangulations and 2d
    planar maps and arrangements.
  o Boolean operations on polygons provided via 2d Nef polyhedra
  o Dependencies on the LEDA library have been removed, except in the
    case of the PostScript stream.

See http://www.cgal.org/releases_frame.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. The CGAL library contains:
  o Basic 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.
  o 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.
  o Interfaces to other packages, e.g. for visualisation, and I/O, and
    other support facilities.

documentation, please visit the CGAL web page:
