So, how exactly does theNintendo 3DSproject images without making you wear a pair of retro red-and-cyan 3D glasses?
The trick is getting our eyes to perceive the pop-out effect without going cross-eyed.

The most iconic way is via red-and-cyan anaglyph glasses, which work with red-and-cyanmovie projectorfilters.
The red lens only emits cyan light, while the cyan one is for the red light.
The images occupy alternating vertical columns of pixels and are filtered through the parallax barrier.
If you look too far to the side, the effect won’t work properly.
