The principle of three-dimensional film is to take two cameras at the same time according to the human eye angle of shooting at the same time in the show also with two sets of video projector simultaneously show to the same side of the screen, about two polarizers in front of the projector’s polarization perpendicular to each other, Viewers use the above bias
