How do Linear Polarized 3D glasses work? To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters. It is best to use a silver screen so that polarization is preserved. The projectors can receive their outputs from a computer with a dual-head graphics card. The viewer wears 3D glasses which also contain a pair of orthogonal polarizing filters. As each filter only passes light which is similarly polarized and blocks the orthogonally polarized light, each eye only sees one of the images, and the effect is achieved. Linearly polarized glasses require...

Why do I need to wear special glasses to view 3D? The reason you need to wear glasses to watch 3D is that a separate image needs to be sent to each eye, with the brain combining the two images into a single image with 3D characteristics. In other words, the 3D process actually fools your brain into thinking it is seeing a 3D image, so it creates one for you.

Why is it called "3D"? The name “3D” is a short-hand abbreviation for “three-dimensional,” meaning that an image or object exists (or appears to exist) on three axes — X, Y and Z. If you think of a piece of graph paper, the X axis runs horizontal across the page and the Y axis runs vertically. This makes up the basics of a two-dimensional (or 2D) image. If you were to put a pencil the center of that piece of the graph paper, the pencil would become the Z axis. You would then have enough axes to create a three...
