Demo: FreeSpace 2 Open with head tracking from Viture Pro XR glasses IMU data – on Linux PC
Until now I used OpenTrack with my DIY IR tracker or the Neuralnet tracker. I knew that my XR glasses feature IMU data though and the xr_driver of the Breezy Desktop project allows to access the data via IPC on Linux PC. So I did what Linux user do: I wrote a script to access the IMU data and forwarded it via UDP to OpenTrack:

This reminded me that I also wrote a proof of concept to implement the FaceTrackNoIR (or OpenTrack) protocol into FreeSpace 2 Open on Linux PC ( https://makertube.net/w/7VtfAjW7EiAUS5aiPwG7if ) so I gave it a spin to test the data bridge. That was smooth sailing!
The mod is Diaspora: Shattered Armistice, still awesome today: http://diaspora.hard-light.net/ (Warning: This may fuel a desire to re-watch the BSG series again
).
The bridge code can be found at https://github.com/bekopharm/xr_to_opentrack (pending changes).
It works with the Breezy GNOME xr_driver: https://github.com/wheaney/breezy-desktop (but the Vulkan one works probably too but that’s untested). It should also be compatible with other glasses that have IMU for Breezy available.
