So far I can draw textured quads (triangle strips), move them and it all works independently of screen resolution and aspect ratio. I'm hitting a huge snag when it comes to collision detection. My only prior experiences were with fixed resolutions with no rotation.
How do you guys handle it? Is there any easy way to get my objects vertices after a translation and rotation? I know how to peek at the model view matrix and it isn't of much help as far as I can tell. I feel like all of my problems would be solved if I could just get the post-transform coordinates of my vertex array.
