*WARNING*: This release features an important change of the CMake scripts
|
||||
used to configure the CGAL libraries and examples. 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. Please read the first paragraph of the release notes
|
||||
carefully.

Using CGAL Header-only
|
||||
### 3D Periodic Mesh Generation (new package)
|
||||
|
||||
- It is now possible to use CGAL without configuring it with CMake, as a
|
||||
header-only library. Note that, even if CGAL is header-only, its
|
||||
dependencies (such as GMP and MPFR) are not all header-only.
|
||||
- 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.
|
||||
|
||||
|
||||
Compiler Support
|
||||
### Classification
|
||||
|
||||
- The Microsoft Visual C++ 2017 version 15.3 has introduced support for
|
||||
C++17, with the compilation flag `/std:c++17`. CGAL 4.12 has an initial
|
||||
support for that flag: the code will compile, but a lot of deprecation
|
||||
warnings will remain. Note that Boost version 1.67 is the first version
|
||||
of Boost supporting `/std:c++17`.
|
||||
|
||||
- The compilation flag `/permissive-` of Visual C++ is now supported.
|
||||
- This package can now handle classification of surface meshes and
|
||||
clusters, and can compute features in parallel.
|
||||
|
||||
|
||||
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.
