Questions about get_differentiable_non_surface() and get_differentiable_x()

haonanhe opened this issue 8 months ago · 2 comments

In the file ./code/model/implicit_morphable_model.py, line 128 and 145, functions get_differentiable_non_surface() and get_differentiable_x() are used. I don't really understand their functions here. I would appreciate it if you could explain this to me. It would be really helpful. Thank you so much.

Hi,

This is the part where we get analytical gradient for points that are on the surface and not on the surface.
You can also check sec 3.3 and equation 8, 9 and 10 for details on this.
