I also started to work on the microstructure deformation paper like Dan. And I was thinking to use SOup for it but I can't get the tension direction.
a) How does the tension map and direction exactly work?
(I am still not sure if the data is comparable to the one I would need to implement the paper)
b) What would be the best way to outsource the direction data as a colored texture like the tension map?
Thank you very much!
