<br>But nothing in nviz when I try 1 and/or 2 (levels of isosurfaces) or the true elevations<br><br>So, <span id="result_box" class="" lang="en"><span class="hps">Is it</span> <span class="hps">possible to represent</span> <span class="hps">this volume in nviz (like in Paraview</span></span>)  <span id="result_box" class="" lang="en"><span class="hps">and if so how ?</span></span><br>

<span id="result_box" class="" lang="en"><span class="hps">I can reproduce</span> <span class="hps">the examples</span> of the <span class="hps">tutorials</span></span> <span id="result_box" class="" lang="en"><span class="hps">but</span> <span class="hps">I realize</span> <span class="hps">that</span> <span class="hps">I</span> <span class="hps">do not understand</span> <span class="hps">the principles...</span></span><br>
