The CGAL Open Source Project is pleased to announce the release 4.13 beta 2 of CGAL, the Computational Geometry Algorithms Library.

Besides fixes and general enhancement to existing packages, the following has changed since CGAL 4.12:

3D Periodic Mesh Generation (new package)

• This package generates 3-dimensional periodic meshes. It computes isotropic simplicial meshes for domains described through implicit functional boundaries over the flat torus (which can also seen in the Euclidean space as a periodic cube). The output is a periodic 3D mesh of the domain volume and conformal surface meshes for all the boundary and subdividing surfaces. The package is closely related to the 3D Mesh Generation package, with similar concepts, classes, and API.

Classification

• This package can now handle classification of surface meshes and clusters, and can compute features in parallel.
