- The package \Verb|luamesh| allows to compute and draw triangulation
+ The package \Verb|luamesh| allows to compute and draw 2D triangulation
of Delaunay. The algorithm is written with lua, and depending of the
choice of the ``engine'', the draw is done by MetaPost (with
\Verb|luamplib|) or by \Verb|tikz|.
\section{Installation}
-\section{The Macros}
+\subsection{With Linux}
+
+To install \luamesh with \TeX live, you have to create the local
+\Verb+texmf+ directory in your \Verb+home+.
+
+\begin{commandshell}
+mkdir ~/texmf
+\end{commandshell}
+
+Then we have to files to place in the correct directories. First, the
+\Verb+luamesh.sty+ file must be in the directory:
+\begin{center}
+ \Verb+~/texmf/tex/latex/luamesh/+
+\end{center}
+and secondly, the \Verb+luamesh.lua+ must be in the directory:
+\begin{center}
+ \Verb+~/texmf/scripts/luamesh/+
+\end{center}
+
+Once you have done this, \luamesh can be included in your document
+with
+\begin{latexcode}
+\usepackage{luamesh}
+\end{latexcode}
+
+\subsection{Dependencies}
+
+This package is built upon two main packages to draw the
+triangulations :
+\begin{enumerate}
+\item \Verb+luamplib+ to use MetaPost via the \luatex library
+ \Verb+mplib+;
+\item or \Verb+tikz+.
+\end{enumerate}
+We will see how to choose between these two \emph{drawing engines}.
+
+Moreover, the following packages are necessary:
+\begin{enumerate}
+\item \Verb+xkeyval+ to manage the optional arguments;
+\item \Verb+xcolor+ to use colors (needed by \Verb+luamplib+);
+\item \Verb+ifthen+ to help the programming with \TeX.
+\end{enumerate}
+
+
+\section{The Basic Macros}
+
+If you want to use this package, you must compile your document with
+\Verb+lualatex+:
+
+\begin{commandshell}
+ lualatex mylatexfile.tex
+\end{commandshell}
+
+Let us recall that this package provides macros to draw two
+dimensional triangulations (or meshes).
\subsection{Draw a Complete Mesh}
+\commande|\buildMeshBW[«options»]{«list of points» or «file name»}|\medskip
+
+This macro produce the Delaunay triangulation (using the Bowyer and
+Watson algorithm) of the given \meta{list of points}. The list of
+points must be given in the following way :
+\begin{center}
+ \verb+(x1,y1);(x2,y2);(x3,y3);...;(xn,yn)+
+\end{center}
+
+\begin{Exemple}
+ \buildMeshBW{(0.3,0.3);(1.5,1);(4,0);(4.5,2.5);(1.81,2.14);(2.5,0.5);(2.8,1.5)}
+\end{Exemple}
+
+\subsubsection{The Options}
+
+There are several options to customize the drawing.
+\begin{description}
+\item[\color{red}\texttt{mode = int (default) or ext}:] the mode option allow to
+ use either the previously described set of point in the argument, or
+ a file, containing, line by line (2 columns), the points. Such a
+ file looks like :
+\begin{verbatim}
+x1 y1
+x2 y2
+x3 y3
+...
+xn yn
+\end{verbatim}
+\end{description}
+
\subsection{Draw the Set of Points}
+\commande|\tracePointsMesh[«options»]{«list of points» or «file name»}|
+
+
\subsection{Draw a Step of the Bowyer and Watson Algorithm}
+\commande|\meshAddPointBW[«options»]{«list of points» or «file name»}{«point» or «number of line»}|
