Media Pipe line Pose - Gaze rotation

Hello everyone

Might anyone be able to point me in the right direction.

I want to use the pose data from the mediapipe line to create some rotational gaze information.

I.e I want to somehow map a circle top to the pose of an incoming dancer. I have adjusted the arc angle of the circle to create a type of beam that starts small in the center and widens as it moves out to the boundaries of the frame.

Is there a way of converting the pose date to control the rotation of the circle so it fits the direction the dancer is looking in?
