Order of vertices from `get_results(...)` output always the same? #22

Hi Bharat and all other readers,

Thanks for all your work, Mr. Bhatnagar. Are the vertices of SMPL-high-res (produced by get_results(m, inp, ...) from test_network.py) always in the same order? For instance I see vertex "1" and "2" are points in the head of the model, on the left side (from the model's perspective). Will this always be the case if I run that function get_results(...)?

I suspect the answer is yes, because two .obj meshes saved at two different times both have the first face as f 6893 3 6892, but I would like a guarantee, because I'm about to write some testing code that assumes it's true.

Also, same question for "regular" low-res SMPL: are the vertices always in the same part of the body?

Thanks, Nathan

Vertex ordering remains the same for both low and high res SMPL

Do you know if this is true for every work using SMPL? (ie. SMPLify-X, HMR)
