3D Images

3D imaging, known as Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. These two dimensional images are then combined in the brain to give the perception of 3-D depth.
Besides the technique of freeviewing, which must be learnt by the viewer, three strategies have been used to mechanically present different images to each eye: have the viewer wear eyeglasses to combine separate images from two offset sources, have the viewer wear glasses to filter offset images from a single source separated to eacheye, or have the lightsource split the images directionally into the viewers eyes.

On the same website, it advertises the use of 3D glasses to reach the full potential of viewing 3D images,
