The 3DS is using a different technique. It's like the lenticular, but on a finer scale (uses a sandwich of liquid crystals, one for display and one to separate the images for the eyes). The problem with it is that it only works in a very small sweet spot. Fine for a portable game system that's always centered in view, and at arms length. But doesn't work for TV with multiple viewers at different distances.
