[Paraview] Three Wall Stereo Projection with Paraview 3.6.1

[Steffen Kaufmann]

Hi Berk,

I read through the wiki, but I do not understand how it works. How is the
workflow / buildup? Let me try to illustrate our hardware buildup and my
understanding.

We have 3 render server, with 2 graphic outputs on one graphic card (for the
passive stereo projection). The machines have ubuntu/debian linux installed.
The projection walls are plain, we have two walls and a bottom (two
projectors per projection target - 6 overall).

On the controlling PC is Windows XP installed.

What I want is to control with the Windows XP - PC the contend which is
displayed in our 3 wall cave. How do I have to start paraview?

I know I have to setup a machine file and server configuration file? But I
don't know how...

How is the command for the pvserver start? I read about:
mpirun -np [NUMBER OF CORES] ./pvserver -m [MACHINE FILE]
--use-offscreen-rendering -tdx=3 -tdy=1

As I understand it starts a pvserver on one Machine, but I need 3 render
servers? How can I start the other servers? How is the paraview application
started? And how can I connect to the servers?

Sorry for the many questions.

Thanks!

Steffen

Hi Steffen,

First and foremost, you need to run pvserver using MPI. Take a look here:
http://paraview.org/Wiki/Setting_up_a_ParaView_Server

I am not sure how your tiled display is setup. If you have one machine
driving each display, you have to make sure that MPI distributed
ParaView with one process per machine. If you have one machine with 3
graphics output driving the whole thing, you have to run all processes
on that machine but each process will have a different DISPLAY set.

Once this is working, you should be able to run ParaView in
client/server mode and see the windows on the tiled-display.

After that, you will have to use the tiled-display arguments when
running pvserver. I believe it will be -tdx=3 -tdy=1 in your case.
