\section{The grid}
The object \verb+grille+ allows you to obtain a solid plane.
The key \texttt{[base=$x{min}$ ${x{max}}$ ${y{min}}$
${y{max}}$]} lets you specify the dimension of the grid. % $
\psset{viewpoint=50 50 20 rtp2xyz,Decran=30}
\begin{LTXexample}[width=6.5cm]
\begin{pspicture}(-3.5,-1.5)(3.5,2.5)
\psSolid[object=grille,
base=0 4 -3 3,
linecolor=gray](0,0,0)
\axesIIID(0,0,0)(4,3,3)
\end{pspicture}
\end{LTXexample}
The key \texttt{[ngrid=$n_1$ $n_2$]} lets you specify
fineness of the grid. If $n_2$ is not set up, it is considered that $n_2 =
n_1$.
If $n_1$ is an integer, it represents the number of grid points along the
$Ox$ axis. If it is a real, it represents the step size along the
$Ox$ axis. For example, the number \verb+1+ is an integer, the number \verb+1.+ is real (note the decimal point).
\psset{viewpoint=50 50 20 rtp2xyz,Decran=30}
\begin{LTXexample}[width=6.5cm]
\begin{pspicture}(-3.5,-1.5)(3.5,2.5)
\psSolid[object=grille,
ngrid=1,
base=0 4 -3 3,
linecolor=gray](0,0,0)
\axesIIID(0,0,0)(3,3,3)
\end{pspicture}
