1. The three-dimensional display device comprising:
a) a two-dimensional display displaying one depthwise image at a time, wherein each depthwise image represents a portion of a three-dimensional object having the same image depth; and
b) a variable focal length MicroMirror Array Lens (MMAL), comprising a plurality of micromirrors, for receiving light from the two-dimensional display and forming a corresponding image of each depthwise image at the required location in space using depth information of the depthwise image by changing the focal length of the variable focal length MMAL.
