Abnormal rigid body info in the stream

[zsll]

Hi

I encountered some problem with the stream from TT.

Here is a typical problematic frame when using 12 markers and two rigid bodies (each containing 3 markers), given by the SampleClient in NatNet.

[Client] Handling packet from 10.208.24.100: Command=7, nDataBytes=372
Received frame 0
Latency (same system) (msecs): 96792832.00

The second Rigid Body ID is obviously wrong and its marker info is missing, while we can see the rigid body tracked and all its data are valid through TT.

This problem happens to both TT 2.0 and TT 2.01, and to NatNet 1.4 and NatNet 2.1. I don't know if this is a problem with the tracking tool streaming or with the NatNet SampleClient. Can you please check it out?

Thanks,

I'm experiencing the same problem. NatNet streaming becomes pretty useless if you only can identify one rigid body. I would love to hear some news from NaturalPoint about this!

We've posted an updated Tracking Tools 2.0.2 build which should fix this issue. You can download it here if you haven't already been in touch with our technical support team.

Then changes are :
* Fixed NatNet streaming for 2+ rigid bodies
