How 3D WorksWe can simulate this by viewing two pictures taken from slightly different angles while cross-eyed

RED / BLUE (anaglyph) 3DWhen light passes through a red or blue filter, it filters out that particular wavelength of light

Taking advantage ofthis and combiningit with binocular visionwe get basic 3D glasses

Polarized 3DPolarizing the two different images projected on the screen allows us to do this in a different wayDoes not distort color
