Hello,
I am attempting to stream only an upper body skeleton by getting participants to do a T-pose, then individually assigning each marker to appropriate rigid body. This method works fine and streams consistent order marker positions of the skeleton from Arena to NatNet.
In NatNet I only get Descriptor_MarkerSet from GetDataDescription. From Arena I have stream: 1) Right Hand Coordinate System 2) 3D Marker Positions and 3) Skeleton as Rigid Bodies checked when I stream. My guess is that it has to do with my set up in Arena. Although I can get the 3D markers out in a consistent order every frame I want to know how to stream the skeleton.
Additionally when I create the skeleton and stream it the scale appears off. When I put the data into matlab I get about 500 units for the shoulder length. My guess is that it is in mm and not cm.
Thanks

Sorry from reading my own post it appears a bit unclear what I am trying to say. Basically I can get the individual markers easily streamed, but I cannot get the skeleton to stream as a set of rigid bodies from arena.

Re: Custom Upper Body Skeleton Streaming to NatNetSDK
Are you streaming rigid body data from arena?

Re: Custom Upper Body Skeleton Streaming to NatNetSDK
The only difference is that I do not have Rigid Bodies checked, just Skeleton as Rigid Bodies. When I make custom rigid bodies they all seem to stream good when Rigid Bodies is checked. I never actually tried it with the custom upper body skeleton. I imagine that will work, and I assume the way I assign rigid bodies is the order they are streamed, and the order that markers are assigned to a rigid body is the order they are streamed within the body. Interesting I will give this a go tomorrow.
Also is there a huge manual for the software Optitrack Arena somewhere, rather than just the Quick Start Up guide?
Thanks,

Yes and no. It's in the process of being written. ETA is very hard to pin down at this moment.
