Per-face Blend Skinning Translations #42

Open Berke-Ates opened 3 weeks ago

Berke-Ates commented 3 weeks ago

Hi!

In task 7 we are required to implement rotation averaging for the faces using the absolute rotations, then perform stitching by solving the poisson equation. If I'm not mistaken, we don't take the absolute translations into account in this approach. Should we average them in a similar fashion as the rotations, use a per-vertex approach, or use something entirely different?

Thanks for your assistance.

Hi,

You should ignore the translation part. Because Poisson stitching solves for vertex positions that minize the error to the target deformation gradients, and in our case the tranlation does not affect the deformation gradients.

Best, Peizhuo
