The charge toward glasses-free 3D displays hasn’t left the iPad out in the cold, as we pointed out a few months back. Now, using a bit of smoke and mirrors (well, mirrors at least) a team from Japan’s Ochanomizu Women’s University (OWU) has developed a novel approach that incorporates a centuries-old artist’s trick to bring “tangible” depth to the iPad’s 2D display.
In the 16th Century, painters developed a technique (dubbed mirror anamorphosis) with which carefully distorted 2D paintings could be viewed in proper proportion from acute angles or using conical or cylindrical mirrors. Probably the best known example is Hans Holbein’s 1533 portrait The Ambassadors with its anamorphic skull – what appears top be a grey streak in the foreground of the painting (below) is revealed as a human skull when viewed from an angle.
