Converting joint in canonical view to camera view?

[wangzheallen]

Is the function converting joint in canonical view to camera view?
'

smplx/smplx/lbs.py

Line 316 in 2144d5c

def batch_rigid_transform(rot_mats, joints, parents, dtype=torch.float32):

'

which means converting 'joints_3d' to 'transform_chain'?

as in the blog: https://ikvision.github.io/

and how to convert joints_3d to transform_chain step by step?

[vchoutas]

This function just computes the absolute joint rotations using the relative rotations and the kinematic chain. The inputs are the parent-relative rotation matrices, the joints at rest pose and the kinematic chain.

Closing this issue since there are no updates.
