I was reading an entry on Wikipedia ( http://en.wikipedia.org/wiki/Image_resolution ) the section on "distinguishable squares" caught my eye.
Is there some fancy expression math trick in determining if a 3D layer is being viewed at >100% scale? Somehow take into account the AE camera distance, FOV, the target layer's pixel dimension and scale? I think collapse transforms would have to be off.
I'm doing a strict Z-move with a camera and my source 4K footage gets a little soft. I'd like a way to ensure its apparent visual scale doesn't go beyond 100% until its off screen.
