What's the origin of coordinate of SMPL? #64

test01 When I visualized the SMPL in meshlab, I find the origin of coordinate isn't the center of pelvis(root). However in the human3.6m, the origin of the coordinate is pelvis(root). Do we need some pre-process before we calculate the loss3d?

Thansk.

Yes the training data aligns the 3D joints by root due to this reason: https://github.com/akanazawa/hmr/blob/8785764a9fb8e5cc88e1c2f283f47782bdcf28fd/src/ops.py#L50
