iphone - OpenGL ES : Revealing underneath view -


I am working on a sample in which I have put two textures on each other. What do I want, whenever the user moves his finger on the screen, he should know after appearing in the form below. I am looking at wiping the front view to reveal the front view.

I want to know some ideas / ideas to implement this feature using OpenGL ES.

This related pointer will be highly appreciated.

Sound execution - Not so intense code can trivial complex tune operation.

You do not have to use OpenGL. You can just front-and-reverse just two images along with the support supporting Alpha channel. Every time you hit or take a hit, you explain a circular patch, the effect is for certain radius or so.

And then Qi pulls up a Radra Redro two bitmaps, first back to the first.

If possible, try to line up a redraw for the area where you have updated the front from the last draw.
