World Frame Determination

Hi there, great work.
I'd like to ask how the world frame is determined. If two synthesized motion representations actually describe the same interaction but the world frames are chosen differently(which makes the global joint positions different), will the evaluation results vary greatly?

Got it. For those who may be wondering(like me), check __getitem__() in interhuman.py. The world frame is chosen based on motion1 at the initial moment.
