Exposing an intersense cube via VRPN
Hi,
I'm trying to set up PPT's MoCap plugin, but I'm a bit confused. The way we are setup is that we have two machines, call them A and B - one with the Intersense cube attached to it (well, the cube is on a helmet attached to the machine) and the other running PPT Studio. The two machines are connected via ethernet. As far as I understand, I need to have a VRPN server running on machine A so that the VRPN Input plugin on machine B can read from it. Is this correct? If so, how do I expose this functionality? Machine B does have Vizard, if I'm missing something there. Otherwise, I have tried to download the actual VRPN server from here: http://www.cs.unc.edu/Research/vrpn/ but I've found a dearth of data on how to configure that server so as to expose the Intersense cube. Does anybody here know? Thank you. |

With the VRPN plug-in in Vizard you can create a server to stream the Intersense data:
Code:
#Add VRPN extension vrpn = viz.add('vrpn7.dle') #Create a server server = vrpn.addTrackerServer('VizardTracker') #Get the Intersense tracker isense = viz.add('intersense.dle') tracker = isense.addTracker() #Set tracker that server uses server.setTracker(tracker) Code:
VizardTracker@Render-PC If the script is not running and streaming data you'll see error messages in PPT Studio when the VRPN Input plug-in is added. |

Thank you very much, that solved the problem.
Is there any way I can run this server "in the background", so that I don't get errors on the ppt machine whenever my main script isn't running? Currently, it looks like worldviz can only run one script at a time. |

If the error message is showing up in PPT Studio before running the script it's not a problem. You probably want to clear the message after the script starts so you can see if anything happens while it's running.

Well, no, the error showing up is that it's not receiving intersense input - not surprising.
Doesn't that hurt the initial calibration I did in MoCap if the server keeps going on and off? |

That should be fine. The initial mocap calibration will not be affected if the stream is interrupted.
