1. A system for recording and displaying images of a three-dimensional object so as to produce a realistic three-dimensional image, comprising: a digital camera having a liquid crystal, electrically controlled, variable focal lens; a computer-controlled system for recording a sequence of images with the camera, at differing focal lengths through the depth of an imaged object, by varying the voltage on the lens; and a display module comprising a stack of display substrates of transmissive type and pixel-selective technology, and generating a display employing one image at each of the focal lengths displayed on each of the display layers, with the shortest focal length on the layer closest to the observer.
