Subject: CGAL 2.3, Computational Geometry Algorithms Library
|
|
Body:
|
|
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 are 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.
