The CGAL Open Source Project is pleased to announce the release 4.11 Beta 1

||||
CGAL version 4.11 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 4.10 in May.
|
||||
release of the final version of CGAL 4.11 in September.
|
||||
|
||||
|
||||
This release is pretty special by its number of breaking changes in the
|
||||
API. In order to have a better feature set, or a better API, several
|
||||
packages have been reworked in a way that breaks the back-compatibility
|
||||
with the previous versions of the API.
|
||||
|
||||
Besides fixes and general enhancement to existing packages, the following
|
||||
has changed since CGAL 4.9:
|
||||
has changed since CGAL 4.10:
|
||||
|
||||
|
||||
* Installation
|
||||
* 3D Periodic Regular Triangulations (new feature)
|
||||
|
||||
- The minimum required version of CMake is now 3.1. All CMake versions up to
|
||||
3.7 are supported.
|
||||
- Added the class Periodic_3_regular_triangulation_3, which provides
|
||||
functionality for 3D periodic weighted Delaunay triangulations. The
|
||||
construction is fully dynamic: it provides both point insertion and
|
||||
vertex removal.
|
||||
|
||||
|
||||
* Generalized Maps (new package)
|
||||
* dD Regular Triangulations (new feature)
|
||||
|
||||
- This package implements Generalized Maps in d dimensions. A generalized map
|
||||
is a data structure enabling to represent an orientable or non orientable
|
||||
subdivided object by describing all the cells of the subdivision (for
|
||||
example in 3D vertices, edges, faces, volumes) and all the incidence and
|
||||
adjacency relationships between these cells. This data structure is the
|
||||
generalization of the combinatorial maps in order to be able to represent
|
||||
non orientable objects.
|
||||
- Added the class Regular_triangulation, which provides functionality for
|
||||
dD weighted Delaunay triangulations. Note that the removal of points is
|
||||
not yet supported.
|
||||
|
||||
|
||||
* 3D Point Set (new package)
|
||||
* 2D and 3D Linear Geometry Kernel (breaking change)
|
||||
|
||||
- This package provides a flexible data structure CGAL::Point_set_3 that
|
||||
allows the user to easily handle point sets with an arbitrary number of
|
||||
attributes (such as normal vectors, colors, labeling, etc.).
|
||||
- Breaking change: The dangerous implicit conversions between weighted
|
||||
points and points in the concept Kernel have been
|
||||
disabled. Constructors offering to build a weighted point from a point
|
||||
(and reversely) are still requested by the concept Kernel but must now
|
||||
be marked with the explicit specifier.
|
||||
|
||||
- Breaking change: The removal of implicit conversions between points and
|
||||
weighted points in the concept Kernel has incidentally created various
|
||||
minor breaking changes in the following packages: 2D Alpha Shapes, 2D
|
||||
and 3D Triangulations, and 3D Mesh Generation. See the full changelog
|
||||
for details.
|
||||
|
||||
|
||||
Note also that the advanced API of a few CGAL packages have change in an
|
||||
incompatible way:
|
||||
- Triangulated Surface Mesh Shortest Paths
|
||||
- CGAL and the Boost Graph Library (BGL)
|
||||
- 2D and 3D Linear Geometry Kernel
|
||||
- 2D Triangulations
|
||||
- 3D Triangulations
|
||||
* Triangulated Surface Mesh Parameterization (breaking change)
|
||||
|
||||
See http://www.cgal.org/2017/04/20/cgal410-beta1/ for a complete list of
|
||||
changes. Breaking changes are highlighted with a bold "Breaking change".
|
||||
- Breaking change: The package has been rewritten and can operate on any
|
||||
model of the MutableFaceGraph concept. All previous parameterization
|
||||
methods are still offered, although with a different, simpler API. The
|
||||
documentation has been updated and offers a gentle introduction to the
|
||||
new API. Users who wish to use the former API must use a version prior
|
||||
to 4.11.
|
||||
|
||||
- Breaking change: The adapter to add virtual seams is now the class
|
||||
CGAL::Seam_mesh in the package CGAL and the BGL.
|
||||
|
||||
- Breaking change: The package has been restructured and most headers
|
||||
have been moved. In a general manner, users should replace <CGAL/XXX.h>
|
||||
with <CGAL/Surface_mesh_parameterization/XXX.h>
|
||||
|
||||
- Add the As Rigid As Possible Parameterization method. This
|
||||
parameterization allows the user to prioritize angle preservation,
|
||||
shape preservation, or a balance of both.
|
||||
|
||||
- Add the Orbifold Tutte Embedding method. This parameterization method
|
||||
allows to parameterize meshes that are topological spheres.
|
||||
|
||||
|
||||
* 3D Surface Subdivision Methods (breaking changes)
|
||||
|
||||
- The subdivision algorithms now work on any model of a
|
||||
MutableFaceGraph. A new API to the subdivision methods is offered,
|
||||
which uses optional named parameters to pass the number of iterations
|
||||
and a vertex property map.
|
||||
|
||||
- Breaking change: Removed the headers <CGAL/Subdivision_method_3.h> and
|
||||
<CGAL/Subdivision_mask_3.h>. The headers <CGAL/Subdivision_method_3/
|
||||
subdivision_methods_3.h> and <CGAL/Subdivision_method_3/
|
||||
subdivision_masks_3.h> should respectively be used instead.
|
||||
|
||||
- Sqrt3 subdivision can now handle input surfaces with a border.
|
||||
|
||||
|
||||
* Scale-Space Surface Reconstruction (breaking change)
|
||||
|
||||
- Breaking change: the API was rewritten to separate the smoothing and
|
||||
meshing algorithm and making it possible for the user to use different
|
||||
ones. The default algorithms used are the same as before this API
|
||||
change, but methods are moved to the classes Weighted_PCA_smoother and
|
||||
Alpha_shape_mesher.
|
||||
|
||||
- Alternative smoothing and meshing methods are provided: Jet_smoother
|
||||
and Advancing_front_mesher.
|
||||
|
||||

||||

|
||||
changes.
