+\commande|\drawPointsMesh[«options»]{«list of points» or «file name»}|\medskip
+
+With the \Verb+\drawPointsMesh+, we plot the set of the points from
+which the Browyer and Watson algorithm compute the triangulation.
+
+The use of this macro is quite similar to the
+\Verb+\buildMeshBW+. Here is an example of the basic uses.
+\begin{Exemple}
+ \drawPointsMesh{(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 (exactly the same that for the
+\Verb+\buildMeshBW+)to customize the drawing.
+\begin{optionsenum}
+\item[mode = int (default) or ext:] this option allows 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}
+\item[bbox = none (default) or show:] this option allows to draw the
+ added points to form a \emph{bounding box} and the corresponding
+ triangulation. By default, these triangles are removed at the end of
+ the algorithm. \emph{Here, because we plot only the vertices of the
+ mesh, there is no triangles, but only dots.}
+\item[color = \meta{value} (default: black):] The color of the
+ drawing.
+\item[colorBbox = \meta{value} (default: black):] The color of the
+ drawing for the elements (points and triangles) belonging to the
+ bounding box.
+\item[print = none (default) or points:] To label the vertices of the
+ triangulations with an adding dot. Without label, there is a dot.
+\item[meshpoint = \meta{value} (default: P):] The letter(s) used to
+ label the vertices of the triangulation. It is include in the math
+ mode delimiters \Verb+$...$+. The bounding box points are labeled
+ with a star exponent, and numbered from 1 to 4.
+\item[tikz (boolean, default:false):] By default, this boolean is set
+ to \Verb+false+, and MetaPost (with \Verb+luamplib+) is used to draw
+ the picture. With this option, it is \Verb+tikz+ the \textit{drawing
+ engine}.
+\item[scale = \meta{value} (default: 1cm):] The scale option defines
+ the scale at which the picture is draw (the same for the two
+ axis). It must contain the unit of length (cm,
+ pt, etc.).
+\end{optionsenum}
+With the same external mesh point file presented in
+section~\ref{sec:buildMesh}, we illustrate the different options.
+
+\begin{Exemple}
+ \drawPointsMesh[%
+ tikz,
+ mode = ext,
+ bbox = show,
+ color = blue,
+ colorBbox = red,
+ print = points,
+ meshpoint = y,
+ scale = 1.3cm,
