Why input size is 25 x 6?
Opened this issue · 6 comments
what a great work!
I'm implementing with your code, but I have a question.
In your paper, Input is orientations in 6D representation of SMPL body model(24 x 6). When I check from debugging, The input shape is 25 x 6.
Which one is right? or What component is added to 24 x 6?
I check that it seems to zero padding.
Can I ask why do this?
The last channel is for global translation. Since its dimensions are 3 and not 6 it's zero-padded.
where is global translation from, it seems to be from the first action2motion joint, but why action2motion switch 0# and 8#?
If I remember correctly, this switching shouldn't be in use anymore. root rotation is at [0] and root translation is at [-1] (only the first 3 entries of it)
The switching seems to be in use:

That's a definition, not a usage, I don't see where this one is being used.
