All About 3D Glasses & 3D Movies
The idea for 3D movies began with the concept of stereoscopy. Many adults will remember View-Masters. These devices looked like binoculars, but slides were put in and viewed for a 3D image, giving the viewer the perspective one would see if viewing the object or scenery in person. Slides had two separate pictures combined to make one picture. The two pictures are actually the same scene, but are taken from a slightly different perspective. One image is presented to the right eye while a slightly different image is presented to the left eye. Combining the imagery is perceived in such a way that appears much more realistic to our minds.
The same stereoscopy idea was used when creating 3D movies. Live 3D movies, that is those which are shot using real human actors, are simply shot using a 3D camera which has two separate angles incorporated into it.
