3D films are fun一of course they are, even the bad ones. But these movies are still in their infancy. The question is whether 3D filmmakers can do better.
I have no doubt they will, but I believe they will achieve cosmetic changes around the edges rather than revolutionary breakthroughs. 3D filmmakers don't realize, or at least have not sufficiently taken to heart, that the medium they're working in is binocular (同时用双目的)film, not merely 3D film. And once one realizes this, it is possible to see that whole fields of potential film experi?ence have been left entirely untapped.
When we say 3D movies, we are referring to stereopisis (立体视觉）. But binocular vision refers to the use of two eyes for vision, whereas stereopsis is just one of the functions binocular vision gives us.
Why do we have such a large binocular vision field in the first place? I have argued in my book，The Vision Revolution，that we have forward-facing eyes in order to see well in cluttered forest habitats. Our large binocular field evolved for seeing past layers of clutter( 一堆杂乱的东西),and integrating two different views of a scene into a single combined view. I call this function of binocu?lar vision “X-ray vision” because it allows us to see the clutter as semi-transparent, something through which to see the scene beyond.
If 3D filmmakers are going to throw binocular images at our big binocular field, then they should be sending us views of the kind that field evolved to process ： views within cluttered environ?ments ,whether leafy forests or spider-web-filled rooms. In this light, 3D film ought to put the viewer into the bodies and eyes of characters in the story，placing him or her into the interactions between the characters and their surroundings. This would allow viewers to truly see out of the eyes of others, to experience other worlds, and yet not have the views of the scenes beyond blocked out, just as in real life. A simple first step forward is to begin calling them binocular movies ，not 3D movies.
