Why 'posedirs' is all 0.?

[masataka46]

Hello Silvia,
Thank you for the code you have created.
However, I have a question when I am running the learning.
I think 'posedirs' in 'my_smpl_00781_4_all.pkl' is used to generate poses, but this value is all 0.
Then, I think that the generated pose will match the T-bone.
During training, class variable 'self.posedirs' is also set to 0.
How do you generate the pose?

Yours sincerely,
Takamitsu Omasa

Hello Takamitsu, The posedirs variable represents the pose-dependent deformations. This is not used in the SMAL model, but it is there because the model has the same structure of the SMPL model for the human body. 3D pose is represented by the variable ‘pose’. Best, Silvia

Thank you for your answer.
I now understand why the variable 'posedirs' is not used.
And I also understand the variables 'poses' and 'weights' to recover the coordinates of the vertices from the poses.
Thank you.
