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.
