the way it works in real life is: they film the movie with 2 different cameras, one with a blue filter, and one with a red filter. Then they go into something like after effects and compose the film from each camera into one comp. To the naked eye it looks scrambled but put on some red/blue glasses and there you go. This is how I have been told it was done so I am not 100% sure. and as for doing it in maya I have no clue. But with this info you might could figure it out in After Effects.
