Motion Representation

1

hello! thanks for your great job! I have some question about motion represention! 1. In Common/Skeleton.py:forward_kinematics_np(), why do specially change first frame's root_quat , that would make root rotation discontinuous....

Is there any case that the 3D joint positions provided by the dataset are local transforms instead of global 3D positions?

root rotation of xz axis

Hi, I'm curious about the root rotation recovery. the recovery of root rotation use `rot_vel = data[..., 0]` in function `recover_root_rot_pos()`, which is calculated by r_velocity. This is delta_theta/2.0 as...

In raw_pose_processing.ipynb, you choose example_id = "000021" and the first frame of it to calculate the target offsets. But it seems that different id and different frame will result in...

The meaning of the vector of a pose in HumanML3D and KIT-ML.

Hi! I'm confused about what each dimension of the 263-dimension vector of a pose in HumanML3D and the 251-dimension vector of a pose in KIT-ML represent(e.g., which dimensions represent the...

Hi, Eric. Thanks for your excellent work. Now I want to get the SMPL parameters from HumanML3D. My question is whether I can get **body_model** from new_joints or new_joint_vec (models...

Hi Chuan, I have been working with the HumanML3D dataset and recently visualized some motion sequences from the HumanAct12 subset. After preprocessing, I noticed that all the motions in this...
