CGAL 4.0.1 released

Changelog

2D Voronoi Diagram Adaptor (re-added)

• The package 2D Voronoi Diagram Adaptor was temporarily removed from the CGAL distribution because of license issues. That package is now back into CGAL.

2D and 3D Geometry Kernel

• Fixed a bug in the Segment_3-Triangle_3 intersection function in the case the segment is collinear with a triangle edge.
• Fixed a bug in the Projection_traits_.._3 class in the case a segment was parallel to the x-axis.

Algebraic Kernel

• Avoid the linking error “duplicate symbols” when two compilation units using the algebraic kernel are linked.

3D Boolean Operations on Nef Polygons Embedded on the Sphere

• Fixed a memory leak due to the usage of an internal mechanism that has been replaced by boost::any. This also influences the packages 2D Boolean Operations on Nef Polygons, 3D Boolean Operations on Nef Polyhedra, Convex Decomposition of Polyhedra, and 3D Minkowski Sum of Polyhedra.

2D Arrangement

• Fixed several memory leaks.

2D Mesh Generation

• Fixed a compilation error in the header <CGAL/Mesh_2/Do_not_refine_edges.h> when g++ version 4.7 is used.

Surface Mesh Generation and 3D Mesh Generation

• Fixed an important bug in the CGAL_ImageIO library, that could lead to wrong result when meshing from a 3D image.
• Fixed the compilation of the demo in demo/Surface_mesher, when Boost version 1.48 or 1.49 is used.

Surface Mesh Parameterization

• Fixed a memory leak.
• Fixed a compatibility issue with Eigen-3.1 of Eigen_solver_traits. This fix also affects the usage of that class in the package Surface Reconstruction from Point Sets.
