1. A 3D image (whether in a movie or in a hologram) is designed to project a slightly different image in each eye, thus giving the effect of being three dimensional (we have added depth). I believe what you're looking for is "Anachrome" visual methods. Please see my source link.
2. There are three visual dimensions in reality _ the dimensions of length, width and height. Time is the fourth dimension we know and live by, but that's beyond this question. When one watches a movie on a screen it is said to be in two dinmensions, with that of width and height. When one is watching a 3D movie the glasses are two colors- red and blue. If one watches a movie intended for 3d viewing without 3d glasses everything will be blurry with red and blue lines surrounding everything sitcking out. The glasses act as a light filter to filter out the blue lines from one eye, while filtering the red lines from the other eye. When the image is recieved by the brain it is interpreted as a three dimensional image which contains length, width and height. I apologize for not having any sources, i learned this through my expirences studying light physics while studying to become a Mechanical Engineer.
