Re: NatNet SDK number of visible markers of rigid body

The NatNet SDK reports marker data in several places: RigidBody Data : Rigid Body Marker data contains the back-calculated, rigid-body "solved" positions of the Rigid Body's markers. This means if a marker is occluded, the marker position will still contain the solved location of where the marker "s...

Re: New MATLAB interface via NatNet 2.5

The NatNet 2.5 SDK ships with both 32 and 64 bit versions of the NatNet managed assembly (NatNetML.dll). You should be able to replace NatNetML.dll referenced assembly in the NatNet Matlab sample with the 64 bit version from the NatNet SDK (in folder .\lib\x64).

Re: Streaming data TrackingTools with Matlab Sample

Hey Stefan, It's possible 2013b added .NET function signatures not supported in 2012. We don't have MATLAB 2012 in house so it is difficult for us to test. I would try commenting out the offending code, or if possible try 2013b. Let us know and we can work forward from there finding a 2012 compatibl...

Re: Stream Nat Net

The NatNet SDK documentation and samples programs should cover how to get labeled marker position data from Motive into your client using either NatNet or a direct depacketization of the UDP packet (see PacketClient.cpp in the NatNet SDK).

hope this helps

Re: Rigidbody c3d File

Hi there,

The C3D format includes support for marker data only (position), not orientation.

Using Motive, you can export to CSV, which is a plain text comma separated format that contains both marker position data and orientation data.

hope this helps,

Re: Streaming Data

Arena supports streaming marker and joint angle data via the NatNet SDK. Are you having trouble getting the NatNet SDK samples to work? If you do not need live export, you can also export your data via C3D or BVH files. Alternatively, our newer software, Motive has several new methods for getting da...

Re: Arena to Unity streaming

Hi there, The NatNet SDK contains a direct depacketization sample (PacketClient.cpp), that shows how to decode NatNet UDP packets directly without needing NatNet lib. If you updated your plugin to use this approach, you could then recompile for Unix (Linux/android/etc). Alternatively, you could use ...

Re: Streaming data TrackingTools with Matlab Sample

Hi Stefano,

The NatNet MATLAB example has been tested against MATLAB 2013b.

Is it possible the version of MATLAB you are using does not support a particular .NET call?

Re: Problem with SampleClient example

<t>The SampleClient outputs all packet data to the console window on the same thread as the data handler. If the console output gets behind (typical at 100 fps with a large data packet) then frames received by the client are dropped. This is normal behavior - the SampleClient is designed to be as si...
