CGAL-4.12-beta1

on GitHub

The CGAL Open Source Project is pleased to announce the release 4.12 Beta 1
of CGAL, the Computational Geometry Algorithms Library.

CGAL version 4.12 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 4.12 in September.

Important Notice

• The CMake scripts used by CGAL have been changed to use modern patterns
  introduced by CMake 2.8.12 and CMake 3.0: instead of setting CMake
  variables, the script now defines imported targets and uses link
  interfaces.

  That is mostly backward-compatible with existing usages of CGAL CMake
  scripts. The only non-compatible effect is that the CMAKE_BUILD_TYPE
  and compilation flags are no longer copied from the CGAL_DIR to the
  project using it. Note also that the CMAKE_BUILD_TYPE is no longer
  set to Release by default. For a developer using the Visual Studio
  IDE or the Xcode IDE, the change should be transparent. Developers using
  makefiles or the Ninja build-system should set the CMAKE_BUILD_TYPE
  to Release manually, to avoid using CGAL libraries without any
  compile-time optimization.

2D Movable Separability of Sets (new package)

• A new package called "2D Movable Separability of Sets" has been
  introduced. It handles a class of problems that deal with moving
  sets of objects in the plane; the challenge is to avoid collisions
  between the objects while considering different kinds of motions and
  various definitions of separation.

  At this point this package consists of the implementations of
  various predicates and constructions related to castings of
  polygonal objects. In particular, it can be used to determine
  whether a feasible mold for a polygonal object does exist. If a mold
  exists, the package can also be used to compute all possible
  orientations of the feasible molds and the corresponding motions
  needed to remove the casted object from the mold.

Classification (new package)

• This package offers an algorithm that classifies a data set into a
  user-defined set of labels (such as ground, vegetation, buildings,
  etc.). A flexible API is provided so that users can classify any
  type of data, compute their own local features on the input data
  set, and define their own labels.

Kinetic Data Structures (removed package)

• This package has been removed from CGAL-4.12. Users of the package
  will have to keep using the source code available in CGAL-4.11 or
  earlier.
