Dear all,
Currently I am trying to implement the page curl effect of a sprite using the algorithm and source from here: http://wdnuon.blogspot.com/2010/05/implementing-ibooks-page-curling.
However, I'm too new to opengl and I'm not able to start.
Here are the questions in my mind:
How can I get the vertices matrix of the sprite and calculate the corresponding new vertices?
How can I draw the new vertices by overriding -(void) draw?
How can I bind the the texture on both faces?
Any help would be very much appreciated.
