CATransform3D matrixes bear a lot of mystery for me. I hope the book will shed some light on how to use them. The math may be beyond the scope of this book, but you could discuss some of the “knobs” it contains: e.g. is there an equivalent to the “focal length” of the camera?
Sorry to get back to you so late. The book does go over the matrix from a ‘how to use it’ perspective but not from a ‘how does it work’ perspective.
Thanks for your interest!
