\section{Third Party Software}
|
|
|
|
In this section we list the software that is used by the various
|
|
\cgal\ packages.
|
|
|
|
|
|
\subsection{Standard Template Library \label{thirdparty:stl}}
|
|
|
|
\cgal\ heavily uses the {\sc Stl}, and in particular adopted
|
|
many of its design ideas. The {\sc Stl} comes with the compiler,
|
|
but it is possible to use the compiler together with an
|
|
alternative {\sc Stl} implementation.
|
|
|
|
|
|
\subsection{Boost \label{thirdparty:Boost}}
|
|
|
|
Boost is a collection of libraries. \cgal\ needs some of them, that is
|
|
it is mandatory. If Boost is not already on your system, e.g., on
|
|
Windows, you can download it from \path'http://www.boost.org'.
|
|
|
|
|
|
\subsection{Blas \label{thirdparty:Blas}}
|
|
|
|
The \blas\ (Basic Linear Algebra Subprograms) are routines that provide
|
|
standard building blocks for performing basic vector and matrix operations.
|
|
In \cgal, \blas\ is required by the packages
|
|
\ccRef[Estimation of Local Differential Properties]{Pkg:Jet_fitting_3}
|
|
and \ccRef[Approximation of Ridges and Umbilics]{Pkg:Ridges_3} only.
|
|
|
|
You can download the official release from \path'http://www.netlib.org/blas/'
|
|
or download optimized implementations from \path'http://www.netlib.org/blas/faq.html#5'.
|
|
Alternatively, installing \taucs\ provides \blas.
|
|
|
|
|
|
\subsection{Lapack \label{thirdparty:Lapack}}
|
|
|
|
\lapack\ provides routines for solving systems of simultaneous linear equations,
|
|
least-squares solutions of linear systems of equations, eigenvalue problems,
|
|
and singular value problems.
|
|
In \cgal, \lapack\ is required by the packages
|
|
\ccRef[Estimation of Local Differential Properties]{Pkg:Jet_fitting_3}
|
|
and \ccRef[Approximation of Ridges and Umbilics]{Pkg:Ridges_3} only.
|
|
|
|
You can download the official release from \path'http://www.netlib.org/lapack/'.
|
|
Alternatively, installing \taucs\ customized for \cgal\ provides \lapack.
|
|
|
|
|
|
\subsection{GMP \label{thirdparty:GMP}}
|
|
|
|
A library for multi precision integers and rational numbers.
|
|
\cgal\ offers adapters for these number types. The usage
|
|
of the {\sc Gmp} library is optional. If it is not already on your system,
|
|
e.g., on Windows, you can download it from \path'http://gmplib.org/'
|
|
or from the Download section of \path'http://www.cgal.org'.
|
|
|
|
|
|
\subsection{MPFR \label{thirdparty:MPFR}}
|
|
|
|
A library for multi precision floating point numbers. The usage of
|
|
the {\sc Mpfr} library is optional, and you must install it when you
|
|
use {\sc Gmp}. You can download {\sc Mpfr} from \path'http://www.mpfr.org'
|
|
or from the Download section of \path'http://www.cgal.org'.
|
|
|
|
|
|
\subsection{Leda \label{thirdparty:Leda}}
|
|
|
|
A library of efficient data structures and algorithms. \cgal\ offers
|
|
adapters to the {\sc Leda} number types. The usage is optional.
|
|
It is only available commercially from \path'http://www.algorithmic-solutions.com'.
|
|
|
|
|
|
\subsection{Taucs \label{thirdparty:Taucs}}
|
|
|
|
\taucs\ is a library of sparse linear solvers.
|
|
In \cgal, it is used to improve (a lot) the computations within the
|
|
\ccRef[Planar Parameterization of Triangulated Surface Meshes]{Pkg:SurfaceParameterization} package only.
|
|
|
|
You can download the official release from \path'http://www.tau.ac.il/~stoledo/taucs/'
|
|
or download a version customized for \cgal\
|
|
from the Download section of \path'http://www.cgal.org'.
|
|
We highly recommend to install the version customized for \cgal\
|
|
which contains an installer, bug fixes, and a complete \lapack\
|
|
implementation.
|
|
|
|
|
|
\subsection{OpenNL \label{thirdparty:OpenNL}}
|
|
|
|
OpenNL (Open Numerical Library) is a library to easily construct and solve
|
|
sparse linear systems. It is the default solver of the
|
|
\ccRef[Surface Mesh Parameterization]{Pkg:SurfaceParameterization} package.
|
|
|
|
OpenNL's main page is \path'http://www.loria.fr/~levy/software/'.
|
|
|
|
\cgal\ includes a version of OpenNL in C++, made especially for \cgal\ by Bruno L\'evy.
|
|
|
|
|
|
\subsection{zlib \label{thirdparty:zlib}}
|
|
|
|
A data compression library.
|
|
It is used in the examples of the \ccRef[Surface Mesh Generation]{Pkg:SurfaceMesher3} package.
|
|
If it is not already on your system,
|
|
e.g., on Windows, you can download it from \path'http://www.gzip.org/zlib'.
|
|
|
|
\subsection{Qt \label{thirdparty:Qt}}
|
|
|
|
A {\sc Gui} library. The usage of Qt is optional, but note that
|
|
it is used for all 2D demos.
|
|
|
|
As Qt is the layer underneath {\sc Kde}, Qt is installed
|
|
on many Linux systems. Otherwise you can download it from
|
|
\path'http://www.trolltech.com'.
|
|
|
|
|
|
\subsection{Coin \label{thirdparty:Coin}}
|
|
|
|
An implementation of Open Inventor. It is used in the demo
|
|
of the \ccRef[Kinetic Data Structures]{Pkg:Kds} package. You can download
|
|
it from \path'http://www.sim.no'.
