axis in SMPL result

See original GitHub issue

I’m trying to animate 3D character in Unity using SMPL 24 joints data. Everything is going well but the only problem is that there is different in Unity and SMPL final data axis.

Below axis are from SMPL data (I draw 3D skeleton using 24 joints from CenterHMR) Screenshot from 2021-01-12 11-50-04

Below image is about axis in Unity WeChat Image_20210112115115

Seems that we need to change the Y and Z axis in SMPL results.

So suggest me that we should swap/change axis (Y and Z) in j3d_smpl24 list that I got from CenterHMR from here or in Unity side?

Thanks for your detailed bug report. I have tested the code at a different codebase. There were something wrong while I pasted the changes to this repository.

At my service. Aha~

I have submitted a commit to support the extra 24 joints in SPIN (compared with 25 openpose joints we already support). With this commit, the result files will contain a key named “j3d_spin24”, which is what you are asking for.

Let me know if there are any problems. Besides, have you converted the output file into bvh? Would you want to share the detailed process with other developers? It seems important for the others. While I am not familiar with these parts. Best.
