Sorry, looks like the connection got dropped earlier (I am on road). I
resent you the shader code. Its not ready for the prime time yet but
hopefully it will give you enough  idea.

Currently volume rendering is not supported out of the box, plus we don;t
have any current funding for it. If you need to get it working asap, I
would suggest look at the VES/Testing code and go from there (I can provide
you guidance as much as I can). Other Idea would be to use ParaViewWeb but
there will be a bit of learning there as well (if you are not familiar with
ParaView).

Thanks,
