i bought three pairs of red/blue glasses off ebay for like five bucks. buy two, get one free. half decent really, they're actual glasses and not paper stuff. GET SOME YOURSELF SUM BEACH
i did some searching and found this image to really pop out. i used it as a reference to make make own 3d fps game, using it to set the correct colors and which side the colors should be on. this image really pops with my set of glasses. the arcs set off into the background and the ship appears to be in front of the screen for to me.
i made this simple fps example to mimick the colors and offsets in my reference.
i rendered two scenes onto some surfaces. there are a few variables that can be adjusted in game: left/right arrows change the spacing of the eyes for the two cameras, up/down changes the angle of them, page-up/page-down changes the fov, ASDW moves, mouse looks, Q changes the left color, E changes the right. i farted around for a while and set some default values. the program remembers your changes. the default values should make the scene pop out some. it does for me. i have a 24 inch monitor. i almost think lights off helps the pop effect too.
i'm not sure if i am getting the effect correct. i think most of the scene is trying to pop out of the screen, but when i swap the colors i can't get the scene to set back into the screen. what do you think? what values would you use for the eyeSpace and eyeAngle variables? is the reference image just photoshopped to perfection? does my simple example not have enough detail?
