Subject: CGAL 3.3.1 Released, Computational Geometry Algorithms Library
|
|
Body:
|
|
|
|
The CGAL Open Source Project is pleased to announce the release 3.3.1 of
|
|
CGAL, the Computational Geometry Algorithms Library.
|
|
|
|
Version 3.3.1 is a bug-fix release for version 3.3. No new features have
|
|
been added in 3.3.1. The following corrections have been made:
|
|
|
|
General
|
|
|
|
- Intel C++ 9 was wrongly recognized as unsupported by install_cgal.
|
|
- Added autolink (for Visual C++) for the CGALImageIO and CGALPDB libraries.
|
|
- Fixed bug in Memory_sizer when using more than 4GB of memory (64bit).
|
|
|
|
|
|
Number Types
|
|
- Fixed bug in FPU rounding mode macros (affected only the alpha architecture).
|
|
- Fixed bug in MP_Float constructor from double for some particular values.
|
|
|
|
|
|
Kernel
|
|
- Fixed forgotten derivation in Circular_kernel_2::Has_on_2
|
|
|
|
|
|
Skin Surface Meshing
|
|
- The new Skin Surface Meshing package had been forgotten in the list of
|
|
changes and the release announcement of CGAL 3.3:
|
|
This package allows to build a triangular mesh of a skin surface.
|
|
Skin surfaces are used for modeling large molecules in biological
|
|
computing.
|
|
|
|
|
|
Arrangements
|
|
- Fixed a bug in the Arrangement_2 package in dual arrangement representation
|
|
for Boost graphs when reporting all halfedges of a face.
|
|
- Fixed a bug in the Arrangement sweep-line when using a specific polyline
|
|
configuration.
|
|
- Fixed bug in Arrangement_2 in walk along a line point location for
|
|
unbounded curves.
|
|
- Fixed bug in aggregated insertion to Arrangement_2.
|
|
- Fixed bug in Arrangment_2 class when inserting an unbounded curve from
|
|
an existing vertex.
|
|
- Fixed bug when dealing with a degenerate conic arc in Arr_conic_traits_2
|
|
of the Arrangment package, meaning a line segment which is part of a
|
|
degenerate parabola/hyperbola.
|
|
- Fixed bug in the Bezier traits-class:
|
|
properly handle line segments.
|
|
properly handle comparison near a vertical tangency.
|
|
|
|
|
|
2D Polygon
|
|
- Fixed bug in degenerate case of Polygon_2::is_convex() for equal points.
|
|
|
|
|
|
2D Triangulations
|
|
- Fixed bug in Regular_triangulation_2.
|
|
|
|
|
|
Interpolation
|
|
- Fixed bug in Interpolation 3D about the normalization coefficient
|
|
initialization.
|
|
|
|
|
|
3D Boolean Operations on Nef Polyhedra
|
|
- Fixed bug in construction of Nef_polyhedron_3 from off-file.
|
|
Now, always the inner volume is selected.
|
|
- Fixed bug in conversion from Nef_polyhedron_3 to Polyhedron_3.
|
|
Polyhedron_3 was not cleared at the beginning.
|
|
- Fixed bug in Nef_polyhedron_3 in update of indexes for construction of
|
|
external structure.
|
|
|
|
|
|
Third Party Libraries Shipped with CGAL
|
|
- TAUCS supports now 64 bits platforms.
|
|
- CAUTION: Since version 3.3.1, CGAL is no longer compatible with the official
|
|
release of TAUCS (currently 2.2). Make sure to use the version
|
|
modified by the CGAL project and available from the download
|
|
section of http://www.cgal.org.
|
|
|
|
|
|
See http://www.cgal.org/releases.html for a complete list of changes.
