I want to get rotation of each joint, like Euler Angles or Quaternion. How to do it?

@vchoutas Could you give me some advice?

@ZewanHuang Hi, sorry for bothering you, but I actually have some doubts regarding the interpretation of the joint angles, precisely what is the starting body position from which the rotation starts? I am now considering a T-pose as starting body position but the coordinates of the joints using the T-pose and the angles are somehow screwed, could you please give some advice?
