Hello Lando
This looks like a really cool project! We will be thrilled to give you support integrating openmocap with the Chordata system.
Out system outputs the pose information using OSC trough UDP or Websockets. You will get an OSC bundle containing the Quaternion rotation for each bone on each cycle.
The XML file you've found is used to configure the Notochord which is the core program of the framework, and takes care of the main tasks such as sensor i/o, and signal processing to get a moving skeleton.
We are currently finishing the implementation of an internal Skeleton structure inside the notochord, so recent versions of the XML have a section which contains a GLTF description of the skeleton under the <Avatar>
tag.
Looking forward to see how your project evolves!
If you need anything you know were to find us 🙂
