Why are the rotation axis of ZJU_MOCAP and wild different

[PolyLiYJ]

I find that in the freeview.py, the rotation axes of different datasets are different. I wonder why are they different. Is the zju_mocap's world coordinates are different from the common-used one?

 ROT_CAM_PARAMS = {
        'zju_mocap': {'rotate_axis': 'z', 'inv_angle': True},
        'wild': {'rotate_axis': 'y', 'inv_angle': False}
    }

yes. zjumocap normalises the smpl poses with the root joint

[sycamore27]

yes. zjumocap normalises the smpl poses with the root joint

But the prepare_wild.py file provided by the author also normalises the smpl poses with the root joint?

It seems not the reason why the zju_mocap's world coordinates are different. Do you know the other reason？ Thanks very much! @Dipankar1997161 @PolyLiYJ
