The release notes for Paraview 5.7.0 says quad-buffer stereo (Crystal Eyes)
active shutter glasses work. However, I can not get “Crystal Eyes” stereo
working with Paraview 5.70.
I am installing Immersive Paraview on a traditional CAVE configuration at NIST.
3 Walls (Front, Left, Floor) in a corner arrangement
Nvidia Quadro RTX card 4 outputs:
X11 Display numbers -
:0.0 Console LCD flat panel
:0.1 Front projector
:0.2 Left projector
:0.3 Floor projector
CentOS 7.7 Linux
Also same problem on a problem on a home system:
Nvidia Quadro P1000
X11 Display numbers: :2.0 Console, :3.0 Front, :4.0 Left, :5.0 Floor
LCD monitors on all
Fedora 30
I believe I have the card, cables and driver properly configured since
glxgears works properly using this command.
I have tried a three process mpiexec pvserver and just single process started
with
praview --stereo --stereo-type="Crystal Eyes"
All other stereo modes work when selected in the GUI. I suspect I am seeing
just one eye. I not entirely sure I have a correct config.pvx file.
I have adapted the one cave.pvx example.
Are there any other config file examples?
Any suggestions on what I should do to get Crystal Eyes stereo working?
@steve, can you provide information on how you’re launching your pvserver processes and also the cave.pvx file you used?
Note the 5.7 Quad-buffer note only refers to the Qt client supporting quad buffer. The support for stereo on the pvserver processes – which is what you’re relying on in this case – should be large unaffected by these changes.
Try launching pvserver with the following arguments as well: --stereo --stereo-type="Crystal Eyes". The arguments are currently needed for both the client and the server processes.
That is what my script does and I have run the paraview command with the two parameters. I have tried evry combination I can think of. Am I missing something?
Just to summarize:
using mpiexec I run 3 copies of pvserver
I run a single copy of paraview
Its a Quadro RTX 8000 running the Nvidia driver 435.21
No that I am using exactly “Crystal Eyes” as the stereo type, I getting stereo.
I’m in the process of creating the correct connections in the VRplugin to VRPN. I will start with the example on the immersive Paraview wiki. If anyone has any additional examples or documentation, please pass them along.
Yes, Crystal Eyes stereo is working on my Quadro P1000.
Note: My xorg.conf is set to create DISPLAYs :1.0 :1.1 :1.2, :1.3 and the P1000 system have common
flat panel monitors and not stereo capable projectors. So I declare its working based on seeing
the double images on the monitors.
Also, I don’t see double images on :0.0 were the paraview client runs. I do see the double image
on :1.1, :1.2, :1.3 (my simulated cave walls).
