Detailed description of the data

[BupyeongHealer]

Hello! This research is fantastic and I want to know about some datasets.
I know about PSI datasets. But this project is a little different.

1. data/sdf/MPH112_semantics.npy => Don't you know what this is for? I saw other sdf files.
2. mesh_ds => What is A,D,U,mesh_0? Is it scene mesh or body mesh? If it is a scene mesh, can you descreibe me about numbering? (ex. A_0.npz for MPH112)
3. data/train/x.npy => What is X? I guess the PROXE coordinate data.
4. data/train/x_semantics.npy => What is x_semantics? I guess the PROXE semantic data.
5. data/train/vertices.npy => Is it full body vertex? or parameter of smplx? or anything?
6. data/train/joints_can.npy => Is it body part like back, butt, thighs, foot and so on?
7. data/train/pkl_file_paths.json => Is it utilize for train code? I think it is not necessary file.
8. data/train/recording_name.json => Also, I think it is not necessary file.

I'm sorry for many questions. Thanks for publishing code and have a good day!
Best regards.
