[Paraview] Paraview 3 in a cave

[Thiebaut Mochel]

Hello,

I'm working at the CECPV (http://www-cecpv.u-strasbg.fr/rubrique3.html), 
a small group at the mathematics  and computer science faculty of the 
University of Strasbourg, France. The CECPV has a Workbench for 
scientific visualization and for testing virtual reality applications.
I'm currently trying to use Parview on the Workbench, that is in cave 
mode. The version I use is Parview 3.1, CVS branch ParaView-3-1-July, 
with openmpi 1.2.4, all that on Fedora Core 4 with the latest updates.
We have three linux computers :
- hpc-g00, the console. It is connected to a CRT display,
- hpc-g01, connected to the first video projector which projects to the 
top display of the workbench,
- hpc-g02, connected to the second video projector, which projects to 
the bottom display of the workbench.

The default host file for openmpi contains :
hpc-g01 slots=1
hpc-g02 slots=1

The file /home/cecpv/paraview/geometry/cave.pvx contains :
<pvx>

  <Process Type="client">
  </Process>

  <Process Type="server">
           <Machine Name="hpc-g01"
             Environment="DISPLAY=:0.0"
             LowerLeft="-1.0 -1.0 0.0"
             LowerRight="1.0 -1.0 0.0"
             UpperLeft="-1.0 1.0 0.0" />
           <Machine Name="hpc-g02"
             Environment="DISPLAY=:0.0"
             LowerLeft="-1.0 -1.5 1.0"
             LowerRight="1.0 -1.5 1.0"
             UpperLeft="-1.0 -1.0 0.0" />
  </Process>
</pvx>

I run on hpc-g00 :
mpirun -np 2 -x DISPLAY=:0.0 /usr/local/paraview31/bin/pvserver 
/home/cecpv/paraview/geometry/cave.pvx

Then, also on hpc-g00 :
paraview --server=hpc-g01 /home/cecpv/paraview/geometry/cave.pvx

paraview starts, but on the top display of the workbench, I see the same 
picture as in the console, and in the bottom display, half of the 
picture. It seems it does only compositing, and ignores the cave mode 
and coordinates completely.

Many thanks in advance to anyone who helps me to make that work.
Thiebaut.
