Hello,

My lab just baught a new 12 cameras optitrack mocap with arena knowing that we already had a 6 cameras optitrack with rigid body. For the communication protocol we used to use the format VRPN for the data sent from rigid body.
Is that still possible with arena ? can we get the data in VRPN format ?

Another question is about OSC protocol, Is it possible to send the data from arena by OSC, is there any library available ?

I have the feeling the only communication possibility in real time with arena is to use Natnet program. I might be wrong ?!?

Thank you in advance for the answer

No the Arena software does not stream data thru VRPN. It uses our NatNet interface.

NaturalPoint (NatNet) Streaming Sample Distribution Files
SDK for capturing tracking data streamed across networks by ARENA and Tracking Tools/Rigid Body Toolkit. Sample clients with source code are included.

We already have installed NatNetSDK but we want to communicate the data by OSC to our MaxMSP programs, is there any library for that or do we have to program it our selves ?

You would have to creat your own interface client program.
