Can you explain why dimension of model output is 225, and dimension of SMPL skeleton is 24*3 ?

[garspace]

I want to convert pkl of output to character animation, but the dimension is not matched, how can i do that?

225 = 6pad + 3trans + 216pose

216pose=24x9=24x3x3

24x3---->24x9

why 24*9

[CuberFan]

why 24*9

scipy.spatial.transform.Rotation.from_rotvec: 24x3------>24x9

[pjgalhardo]

225 = 6pad + 3trans + 216pose

@CuberFan pad as in padding? If so, why do you need padding here?

why 24*9

the size of rotation matrix is 3*3
