I need to do an application similar to this [Morfo] http://itunes.apple.com/us/app/morfo/id418900007?mt=8 . And I posted a question [here] http://stackoverflow.com/questions/1...face-in-iphone where the answer states the solution is "[Displacement Mapping]" http://wiki.blender.org/index.php/Do...l/Displacement . And I googled this to do it in opengles. I couldnt get how to start and implement this in opengles. Can someone give me some starter on this?
