Nintendo 3DS: How does the 3D effect work?

Nintendo 3DS offers the ability to create beautiful 3D images on its ickle screens. But how? A video recap to see how it works.

The idea behind 3D images revolves around creating two separate outputs at ever-so-slightly different angles: one for your left eye and the other for your right - each the average distance between your visual balls. Until now the older glasses approach has filters on each eye to block out the other to achieve the 3D effect.

The 3DS instead uses parallax barrier - directing one image to your left eye, and the other to the right - like a vent with tiny shutters, so small that your brain doesn't notice and combines the two to form a single, 3D image.

Baffled? Kombo has put together a video guide describing the concepts behind Nintendo's new visual beast.
