Even your 3D movie glasses use filters now.
An Ontario-based company has created a pair 3D glasses that uses filters to manipulate 3D image streams.
In most stereoscopic displays (3D displays), two image streams are projected simultaneously on one screen. In 3D movies, the two image streams are identical but one is positioned off-center to simulate depth when viewed through a pair of 3D glasses
With that knowledge of 3D displays, PipeDream Interactive created Invisivision to isolate one of the two image streams using filters. Instead of using two identical image streams in a 3D display, a filmmaker could create an image stream with different content. With the filters down, the viewer will see one of the image streams.
