Hi Johannes, <div><br></div><div>Utkarsh is right and what is suggested could work for you. I also remember someone asking the same question in this mailing list and that person was able to modify the volume rendering code to make it work in the CAVE. I have to find the information but I believe that was the case. If you don't find that email in this list, let us know unless you want to take the route suggested by Utkarsh. </div>

convert the data to unstructured grid (using Tetrahedralize filter)<br>
and then volume render that.<br>
