Displays like the CAVE can be formed in various configurations. In ParaView these configurations can be specified using the PVX configuration XML file.
Where to specify this?
- pvx file can be specified as the last command line argument for any of the server processes.
- Typically the pvx file is specified for all the executables whose environment is being changed using the pvx file. In case of data-server/render-server configuration, if you are setting up the environment for the two processes groups, then the pvx file must be passed as a command line option to both the executables: pvdataserver and pvrenderserver.
- When running in parallel the file is read on all nodes, hence must be present on all nodes.
Structure

<Process Type="server|dataserver|renderserver">
<Machine name="hostname"

- Only 2 vectors ([LowerRight - LowerLef] and [UpperLeft - LowerLeft]) are needed, the third vector is computed from these 2.
Cave Rendering
Instructions
- Turn on
PARAVIEW_USE_MPIandPARAVIEW_USE_ICE_T - run the servers using the pvx file:
mpiexec -np 2 pvserver cave.pvx - start and connect a client
Notes
- See below for an example of a cave configuration file
<source lang="xml"> <?xml version="1.0" ?> <pvx>
<Process Type="client" />
<Process Type="server">
<Machine Name="Erna"
Environment="DISPLAY=:0"
LowerLeft="-1 -1 -2"
LowerRight="1 -1 -2"
UpperLeft="-1 1 -2" />
<Machine Name="Erna"
Environment="DISPLAY=:0"
LowerLeft="1 -1 2"
LowerRight="-1 -1 2"
UpperLeft="1 1 2" />
</Process>
</pvx> </source>
- See vtkCaveRenderManager::ComputeCamera for more information on how the coordinates are used to configure the cameras
- The rendering on the server is full screen by default. If you want the windows to be smaller for debugging, set the environment variable PV_ICET_WINDOW_BORDERS=1 on the client machine.
