Summary: CGAL 4.5 Beta 1 Released
Project: CGAL


The CGAL Open Source Project is pleased to announce the release 4.5 Beta 1
of CGAL, the Computational Geometry Algorithms Library.

CGAL version 4.5 Beta 1 is a public testing release. It should provide
a solid ground to report bugs that need to be tackled before the
release of the final version of CGAL 4.5 in October.

Besides fixes to existing packages, the following has changed since
CGAL 4.4:

o Support

- CMake version 3.0 is now supported.

- Microsoft Windows Visual C++ compiler 2008 (VC9) is no longer

o Triangulated Surface Mesh Deformation (new package)

This package allows to deform a triangulated surface mesh under positional
constraints of some of its vertices without requiring any additional
structure other than the surface mesh itself. The methods provided
implements an as-rigid-as-possible deformation.

o Breaking change in the support of Boost Graph Library

- Introduction of the FaceGraph concept.

- Cleanup of the HalfedgeGraph concept. In particular:

- Deprecation of halfedge_graph_traits.

- A model of HalfedgeGraph is considered as an undirected graph. Thus any
call to edges() should be replaced by halfedges() and num_edges() now
returns the number of (undirected) edges.

- Breaking change: is_border_edge and is_border_halfedge properties are
removed. The free functions is_border() and is_border_edge() should be
used instead.

o 3D Triangulations

Add an experimental parallel version of the Delaunay triangulation and the
regular triangulation algorithms, which allows parallel insertion and
removal of point ranges.

o 3D Mesh Generation

Add an experimental parallel version of the 3D mesh refinement and mesh
optimization methods.
