Structure of smpl_key.json

• If the structure of a SMPL file (.pkl) is as follows:

  # At least contains the 'pose' and 'mocap_trans'  
  smpl_sample.pkl/
  ├──'first_person'
  |  ├── 'pose' # (N, 72) or (N, 24, 3, 3)
  |  ├── 'mocap_trans' # (N, 3)
  |  ├── 'lidar_traj'  # (N, a), a ≥ 4 and coordinate xyz in [:, 1:4]
  |  ├── 'opt_pose'  # (N, 72) or (N, 24, 3, 3)
  |  └── 'opt_trans'  # (N, 3)
  ├──'second_person'
  |  ├── 'pose'  # (N, 72) or (N, 24, 3, 3)
  |  ├── 'mocap_trans'  # (N, 3)
  |  ├── 'opt_pose'  # (N, 72) or (N, 24, 3, 3)
  |  ├── 'opt_trans'  # (N, 3)
  |  ├── 'point_frame'  # (n, ) n ≤ N, 'point_frame' ∈ 'frame_num'
  |  └── 'point_clouds'  # (n, 3) n ≤ N
  └──'frame_num' # (N, )

  and I want to visualize the SMPL pose from pose field and trans field of the second_person, and name this SMPL model as Basedline1(S), I can add content in smpl_key.json as follows:
