And even more importantly, even if it may differ slightly in its method, as long as the final product appears the same to the viewer, does it really matter if the process for getting there is different?

One thing I've found with Swift is that you can't animate a a camera along a curved path. However, you CAN animate multiple short straight paths. As long as you keep the absolute distance between the camera and the target/focal point fixed (or changing at a constant rate), AND you move the camera manually a short distance every frame or two, it appears to be following a curved path. Is there really a difference to the viewer? "No." Is it the same thing? Also, "no." Does it matter then, that they are different? Once again, "no."

I find that I use this concept again and again when doing my 2D stuff. Sometimes erasing something distorts another part of an object, so, instead, I mask and cover parts with whatever is behind them. It then appears as if that part were erased, but in reality, it isn't. This is like a partial "move to back," but only with the part I want obscured. This wouldn't work well with 3D, though.
