hello.
I have question about this framework.
this app works greats.
But on some dataset, It obtained crashed results.
(I used face mask dataset from Robert W. Sumner Site)
I didn't know what actaully happended here. (I think it was occurred by numerical issue..)
this is my one of my results.
video
(back face in result)
Any advice would be appreciated.
thank you.

I find it is hard to converge, do you have any good debugging method?
First thanks for making the code public!
I am trying to use the code in geodesic.py to compute the geodesic distances for a given triangular mesh, however I am getting nan outputs. Any ideas? Many thanks in advance!
Below are some debug information I printed out:

Hello:
Thank you for sharing the amazing work. In the paper there is a user input binary mask feature. Could you point out how can I use that feature in your code? thank you!
