The present invention relates in general to systems for and methods of three-dimensional viewing of displays and projections. One embodiment two layers () are uniform polarizing filters and a birefringent layer with individually switchable elements () is sandwiched between them. Together these layers () constitute a parallax layer (). This parallax layer () is located at a certain distance from a display (). This placement, and the existence of opaque areas on the parallax layer () which permits to a viewer see a three-dimensional image. The individual elements () of the birefringent layer () are controlled by a control element (), which is in communication with a head-tracking sensor (). This allows the individual elements () of the birefringent layer () to be selectively turned on and off according to the position of the viewer's head.
