definition of shape and pose parameter about manotorch HOT 4 CLOSED

Hi, if you already have the euler angles of each joints/articulation on the hand, you can follow the joint orders described in compose to customize your hand pose.

demo example here

In order to dive deep of the shape and pose parameter defined in original MANO,
you can visit paper: Embodied Hands: Modeling and Capturing Hands and Bodies Together.

As for the demo code in your screenshot, it is just a bare demo of how the manolayer was called. We use the use_pca=True to use the low-dimensional 15 PCA pose components to control the total 15 joints (45 DoFs in MANO).

Best,

Thanks for your reply.
By the way I have another question about this code .

The intermediate tensor close_face is not moved to "cuda",so I guess the manolayer module could not run on GPU if I don't manually modify the code?

Correct,

This closed_faces is designed for drawing the hand without open hole at wrist.
If you want use faces on GPU,
I recommend you manually forward the close_faces to target device,
or, use the MANO's default faces: th_faces, which is bound on GPU.

Hi, I found this thread somewhat helpful, thank you.
However, I'm encountering an issue with my approach. I'm utilizing 21 keypoints (x, y, z) to construct vectors and calculating angles across different axes by projecting onto the XY, YZ, and ZX planes. Then, I use the compose function to generate a mesh using MANO, but the mesh output closely matches only a few datasets from MANO. Currently, I'm only employing the pose parameter for this purpose and not the shape parameters.
Just want to check is this approach right?
