I was just wondering if someone knows about some good library or tutorial on how to achieve a 2D distortion of a face taken from an image taken by the user.
I would like to achieve a similar effect to the one in Fatify, Oldify, all those Fat Booths, etc., because I am creating an app where you will throw something at the face and I would the face to jiggle and move when the object hits it.
How should I do this?
