How to Visualize Wrist 3d Position Coordinates？

[horizoneee]

Thanks for your excellent work!
I was confused that how to visualize the coordinates of the wrist position? Currently, I can only find 15 key points of the fingers from /results/joint_3d/scene_01__A001++seq__4c966751912ef4687b87__2023-04-27-18-41-04/egocentric/hands_joints.txt, and I can only read the quaternions of each key point of the hand from complex_task_data["smplx_param"]['left_hand_pose']. I didnot find the 3D coordinates of body key points.
Do the 3D coordinates of the wrist need to be inferred from the SMPL-X model?

Thank you for your interest in OakInk2 dataset!

I am not sure where this path comes from: /results/joint_3d/scene_01__A001++seq__4c966751912ef4687b87__2023-04-27-18-41-04/egocentric/hands_joints.txt. Could you provide more context?

You can obtain SMPL-X upper body joints by decoding SMPL-X parameters. Refer to the oakink2_viz_gui tool's implementation for more details.

Additionally, you can obtain MANO joints (including the wrist keypoint) by decoding MANO parameters. Refer to the oakink2_viz_seg3d tool's implementation for more details.

Hope this information helps!
