SMPL mesh obtained from 3D keypoints

[Lqm26]

Thank you very much for your time and for the outstanding contribution to the field.

I have a question regarding the mesh reconstruction process using SMPL in your method. In the paper, you mentioned the use of SMPLify-X; as far as I understand, SMPLify-X typically fits the SMPL mesh from 2D keypoints. However, in your work, it seems that the mesh is obtained from 3D keypoints?

I would greatly appreciate it if you could clarify how you performed the SMPL fitting from 3D keypoints. If possible, I would also be very grateful if you could share any related code or implementation details.
