Warp \ bend effect on a UIView?

Question

I\'m trying to get a similar effect to the one described in the pictures. The white area on the left isn\'t on the original photo, it pushes the pixels away

Answer 1

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)
