How can i get the RigidBody Data

Post by Seongjoo » Thu Mar 30, 2017 12:53 pm

Hello, I use Motive:Tracker

I attached four markers to the drones.
Motive detected the markers.
I create a rigid body and named it drone.
I check the project tap and Rigid body real-time info
- Drone

Ridgid Body:Drone
Real-Time Info
(4 of 4 markers)
X -372.862
Y -36.840
Z 1895.850
I use NatNet SDK and I tried to data streaming(Using code based sample project)

But I could not get rigid body data
Why the sample say Rigid bodies [Count=0]
How can i get the real-time Info?

Sample Log
FrameID : 1077862
Timestamp : 8982.18
Latency : 8982.18
Timecode : 00:00:00:00.0
Other Markers [Count=0]
Rigid Bodies [Count=0]
Skeletons [Count=]
Labeled Markers [Count=4]
Labeled Marker [ModelID=5, MarkerID=1, Occluded=0 ~
Labeled Marker [ModelID=5, MarkerID=2, Occluded=0 ~
Labeled Marker [ModelID=5, MarkerID=3, Occluded=0 ~
Labeled Marker [ModelID=5, MarkerID=4, Occluded=0 ~

Hi Seongjoo,

Have you tried running the pre-compiled samples to see if the rigid body is displayed there? I would suggest running the WinForms Test App.

You may also want to check your Stream Settings in Motive, to be sure Rigid Bodies are enabled. ... g_Settings

If you continue to struggle with this, please feel free to reach out to us directly at
