How can I manually rotate an avatar's head? about audio2photoreal HOT 2 CLOSED

Thanks for your interest in our work!
Hmm it might be a bit difficult to manually rotate the neck joint and have the rest of the texture look correct (e.g. gaze)
But in theory it is totally possible to rotate just the head. I need to ask around to see what the skeletal parameterization is to isolate which joint it is in the 104-d vector, but ill reply once I find it.

From our resident skeleton expert Javier:

The neck joints are the following:
neck twist: 12 (azimuth)
neck lean: 13
neck bend: 14 (neck elevation)
head rz: 15 (head elevation)

That said, turning only the neck to make the avatars look each other is going to make it look pretty weird. It's pretty uncomfortable to turn your neck a lot, so people typically rotate their torso and/or distribute that rotation across the whole kinematic change from pelvis to neck.

Hope this helps!
