[Paraview] Paraview enabled VR Plugin not interacting via VRPN

Mon Feb 9 20:44:16 EST 2015

Hi Aashish,
Thanks for the prompt reply!
1) Yes it is a valid VRPN server, and the vrpn.cfg file is set up correctly. When I run vrpn_print_devices with "Mouse0 at localhost" as the argument I get correct button and analog feedback. I have read that in the VR Plugin, the address should be "<device>@<hostname/IP>", therefore Mouse0 at localhost should be correct.
2) I am unsure of what to do for the interaction in the VR Plugin, there doesn't seem to be a lot of options available, is there some sort of example configuration you could give me as a starter? I do not have access to a tracker, is interaction achievable without one?
Basically I just want to be able to move the camera, or interact with an object using devices through the VRPN. I am starting with the mouse (Mouse0) because I know it works on other applications and on the VRPN, so I am assuming the trouble I am having is with my Paraview configuration. After I have set up simple interaction with the mouse I will move onto other devices that VRPN supports, such as the 5DT Data Gloves. And an example of the interaction I want is to be able to turn the camera left when the mouse moves left, right when it moves right, forward, backward, and to be able to grab the object on click.
Thanks,Hannah

Hannah, 
Thanks for sending the files. Couple of thigs: 
1) Is this really a valid VRPN server Mouse0 at localhost? Can you use vrpn_print_devices program to communicate with it? 
2) Looks like you the property you configured is visibility but the style you have chosen is vtkVRGrabWorldStyle which requires tracker or otherwise it won't do anything. 
Can you describe it in bit more detail on what exactly you are trying to achieve? What hardware you have?

Hi,
This is my process:
Start Paraview serverStart VRPN serverStart Paraview clientAdd an object (box)Add VRPN connection in the VR PanelAdd VRPN interaction in the VR PanelPress "start"
Is there anything I am missing?Elsewise I can give more information about my VRPN, however I'm assuming I'm doing something wrong/missing something with the Paraview setup.
I have saved the project and VR state files and attached them.
I am using Paraview 4.3.1 (32bit) on Windows 7 (64bit).
Thanks for your help,Hannah

Hi,
I recently compiled Paraview from the source code to enable the VR Plugin.
I have built VRPN, and compiled Paraview using that VRPN's dependencies.
However, when I add the connection and interaction in the VR Plugin in Paraview and press "Start", when I (for example) press the button I have registered down, the interaction doesn't happen. And on my server it says:
"vrpn: Connection requiest received from 'IP address': 'IP address' 'Port'Get a new connection, reset virtual_Tracker"
Is it possible for you to share the VR state file? Or provide information on how you setup the VRPN server in the first place? Seems like a configuration issue.  Also, helpful to know the version of ParaView and the OS you are using?  
Any idea if I have just not setup my connection/interaction correctly in Paraview? The VRPN server works fine for other applications such as Vizard.
Thanks, 
Thanks in advance for any guidance,Hannah
