How to get 6DOF with older 3DOF XR glasses using Breezy and OpenTrack

Breezy can now turn a 3DOF (degree of freedom) device into a 6DOF device by augmenting the missing positional data from a webcam. Spoiler! It is not the cam strapped to my face - this is just for the demo you're watching right now. The cam, that I used for this task, is sitting on my monitor. How this works? Well not with magic! This requires a somewhat decent webcam - really anything from the last decade should suffice - and OpenTrack, of course. OpenTrack is a head-tracking application with multiple tracker plugins. One of it's plugins is the Neuralnet Tracker, an AI powered extension that comes with a bunch of different head pose models to choose from. With a webcam connected this can now _locally_ run the detection model with very low latency - so it's usually blazing fast on most systems! This alone is already 6DOF and is used a lot for gaming already - so what does Breezy do with this? Simple! It reads the forwarded data via an UDP listener, a very quick way to transmit data o
