Example of some OSC joint output:
/userid/jointname x y z confidPosition [Xx Xy Xz Yx Yy Yz Zx Zy Zz orientPosition]
It has been casually tested with Max 5 and 6, SensorKinect, and OpenNI binaries on Windows and Mac OSx. If you find problems and can reproduce them with clear steps, I encourage you to open an issue at https://github.com/diablodale/jit.openni/issues
This external's output is very similar to jit.freenect.grab and therefore it can often be used in its place with small changes. My object outputs depth in mm and jit.freenect.grab outputs in cm. A simple math operation can resolve this. Note, my object does not provide the "raw" values of jit.freenect.grab; instead it provides the mm depth values via OpenNI.
The OSC skeleton data should be easy to use if you are familiar with OSCeleton.
I would like to see support for other generators (gestures, hand point, etc.) in the future added by myself or with the assistance of others.
