<p style="margin: 0px; text-indent: 0px;"><br>
</p>
<p style="margin: 0px; text-indent: 0px;">I am trying to use
pst-solides3d to plot a function of the form z=f(x,y). <br>
</p>
<p style="margin: 0px; text-indent: 0px;"><br>
However I don't know how to specify the maximum value of z. The
bonus would be to jump over division by zero.<br>
</p>
<p style="margin: 0px; text-indent: 0px;"><br>
The following example uses pgfplots and does the job. But I want
to use pstricks ;-)<br>
