<div>Hi Zach, et al.,</div>

<div>I'm making progress here. I looked at Sebastien's suggestion of using VirtualGL but decided to go back and build a VM with X11 support. I've got Midas running and ParaView web configured as per the web site and Zach's instructions. When I got to view an
object (a 3D CT stored in .mha format) I get a blank canvas with "Volume rendering: pe0017s4.mha" on the top and a bunch of control widgets on the right.</div>

<div>That saved a lot of time! A couple of dummy questions. In /var/www/midas/modules there is already a pvw directory. So where am I supposed to create the symbolic link to $PARAVIEW_ROOT/lib/paraview-4.0/www?</div>

<div>You should create a symlink at /var/www/midas/modules/pvw/public/import, and it should point to the paraview-4.0/www dir.</div><blockquote type="cite"><div>

<div>Also, just because I'm kind of dense, do I need to set the DISPLAY environment variable. The pop-up help says "If the DISPLAY env var should be set…" I don't know if it should be.</div>

to set it. If you open a terminal and type</div>

<div>We just finished transitioning the demo application to the latest version of ParaViewWeb. The demo of the old capabilities is here:

<div>You'll need to build Paraview Web from Source or download binaries. It comes with paraview, so you should be able to follow the instructions stemming from this wiki page:</div>

<div>Hello Midas World,</div>
<div><br>
</div>
<div>I'm trying to build an instance of Midas with ParaviewWeb enabled. I'm working on an Ubuntu 12.04 instance. Midas built fine, but I'm having a difficult time getting Paraview to build. Just curious if the paraview-python package that is available in the
ubuntu distribution is sufficient for this purpose? If it is, curious about the details of the configuration for the instructions: "Make sure to symlink the www directory of your ParView build directory…"</div>
</div>
<div><br>
</div>
<div>I'm suspicious of the package since when I try to run pvpython I get an error:</div>
<div><br>
</div>
<div>"Error converting executable file "/usr/bin/../lib/paraview/pvpython" to real path: no such file or directory"</div>
