One last question and Ill shut up. How exactly does "sending eye dependent images" work? Is it just due to the slightly different angles each of your eyes view the screen, or something deeper than that?
It's easy. Watch this video and you will understand:

For everyone that don't understand how sharp's screen works, this test will explain:

But it's not diferent from what I say here:
1 - 3DS make a vetorial image. Polygons, fisic, AI and other effects are make only a time here.
2 - From that scene are take 2 pictures. Now 3DS will apply the "maps" from this pictures with the right light for both angles. Bump mapping, reflective mapping, transparency mapping, normal mapping and other will be processed twice. It's can look difficult but I believe that it's simpler than make it for a split screen game. The final result are 2 pictures:
LLLLLLLLLLLLLLLLLLLL RRRRRRRRRRRRRRRRRRRR
LLLLLLLLLLLLLLLLLLLL RRRRRRRRRRRRRRRRRRRR
LLLLLLLLLLLLLLLLLLLL RRRRRRRRRRRRRRRRRRRR
LLLLLLLLLLLLLLLLLLLL RRRRRRRRRRRRRRRRRRRR
LLLLLLLLLLLLLLLLLLLL RRRRRRRRRRRRRRRRRRRR
3 - Now using the sharps dual layer screen, we has a result like a interloped image:
LRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLR
LRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLRLR
The first video i put in this post show how the barrier take that one screen and send the rigth imagem for the rigth eye. It's simple in the end.
Of course that a developer that don't use 3D will have a "extra-power" to make his game. But don't think it's a lot. Understand?
