I implemented a proof of concept to add the FaceTrackNoIR (or OpenTrack) protocol into FreeSpace 2 Open on Linux PC. Apparently only TrackIR and FreeTrack (both Windows only) are supported so far. Still needs some fine tuning but I'm really happy with that single day coding frenzy considering that I didn't touch C++ in years.

I never did create a merge request so far. I'm still going to but it's really low priority for me rn :-/

This is a demo of the implementation with Diaspora: Shattered Armistice, a BSG mod for FreeSpace 2 Open. It's also on YT should you fancy that: https://www.youtube.com/watch?v=vRB8lRV1m54
