    This isn't new tech. Fairly certain this is the method. Heard of this a long time ago.

    What this means:     A filter is over the screen (adjusted by the slider on the right?) which limits the pixels that can be viewed by each eye. That is why you can't be too far to one side or the other. When the image is processed in your head, magic happens (3D effect).

    Not sure if this is the exact method I was thinking of but the closest I could find from a Google search.

    It's been known for a long time that it uses a parallax barrier to display 3D.

    Nope, it sure isn't new tech. In fact there was a model they showed on TechTV (before it became G4) On The Screen Savers, and it was marketed as a gaming laptop, and they played Battlefield 1942, and had to stop after 10 minutes or so because the effect was headache inducing.

    yeah currently paralax barriers would be the only plausible way to do 3D without glasses.

    That's the original article I've been looking for. The one in which I first heard about it. Thanks!

    The method might be correct, but the filter never gets adjusted, the software renders the image twice, once from the left and once from the right. The slider changes how far left or right the two images are rendered from. If you changed the filter in any way it would completely f*ck up the effect, the filters have to remain exact.
