Question Page turning animation

I am trying to make a page turning animation

I can draw the animation of the page turning

but my issue is the deformation of the contents of the page, I wanted the contents of the page being turned to be dynamic.

Lets say I have an animation that goes like this:



How do I map something like a render texture to the parts of the page that are getting deformed?

 

Check out these, hopefully one of them helps:

 

I think these are half way there

they are masking part of the page as it travels

But they are missing the distortion of the contents of the page

How can I distort an image more or less like what happens in the animation I posted?

 

Try posting this in the animation page or shaders. Those groups may be of better help
