Hey.
I was wondering whether there is a way to detect a touch in an OpenGL rendered scene. What I have i a set of images which are being rendered in my main view. Now if the user touches one of these images (or objects) I would like to know which one was touched - similar to the
CGRectContainsPoint(frame, [touch locationInView:self.view]
method.
Is there an easy way to find out? If there is none, this would also help.
