Plugin For Headtracking with webcam via FaceAPI

[Adam]

I am trying to work that FACEAPI integration for headtracking via streaming position and orientation data from a socket and can't quite get it to work.

Could you look over my code and let me know what I may be doing wrong? The socket works and I can access the data, but I can't seem to get it to apply to my viewpoint.

Thanks,
