format of VRPN data from RigidBody

Post by tab » Tue May 13, 2008 5:18 am

Hello,
I am streaming data from VRPN streaming engin from Rigid Body. I have script in python that listen port 3883 and sending results like this:

'vrpn: ver. 07.13 0\x00 \x0b\x00\x00'
'vrpn: ver. 07.13 0\x00\x14\x0b\x00\x00'
'vrpn: ver. 07.13 0\x00\xfc\n\x00\x00'
'vrpn: ver. 07.13 0\x00(\x0b\x00\x00'
'vrpn: ver. 07.13 0\x00 \x0b\x00\x00'
'vrpn: ver. 07.13 0\x00\x14\x0b\x00\x00'
'vrpn: ver. 07.13 0\x00\xfc\n\x00\x00'
'vrpn: ver. 07.13 0\x00(\x0b\x00\x00'

Do you know what format of data is this?

Thanks
Peter

It looks like you are not using the latest Rigid Body software, we'd recommend upgrading (it includes VRPN version 0.715).

To read the VRPN data, the best thing to do would be to use one of the open source VRPN implementations available here : http://www.cs.unc.edu/Research/vrpn/

Also of note, the you can download the VRPN source code which includes encoding/decoding if it's data stream.
