Flip page shader Multitouch

Hello at all,
I’m working to a new installation where we will simulate the flipping movement of page.
I see the page Shader but I need a little bit sofisticated shader for my work.
Here there’s an example made in Unity https://www.youtube.com/watch?v=NQbha2tOY5Y

Anything can help me?
