Hi, Is Core Animation the best tech to use for 2.5 D animations like Cover Flow or the transitions in Keynote and iPhoto? I want to develop apps with cover flow like interfaces (2 D objects moving in 3 dimensions). I am looking for good books/tutorials/guides on this. Most of the Core Animation stuff I read (from Apple and books) doesn't apply to iOS and is targeted towards the Mac. I'm starting from scratch, although I know basic 2-D UIView animations. So can anyone tell me where to start? Also what's the difference between Quartz and Core Animation?
