Question about the coordinations

[LarkLeeOnePiece]

Thanks for your great work.
I am confused about the coordination of the output.
There are global transl and orientation. I am a bit about which coordination they lie in.
Are they in the camera space or a world space you define? if That's the world space. How can I find the transfomation matrix between the SMPL and the world coordination?
