An apparatus projecting 3D autostereoscopic images viewers. The apparatus includes a projector array with projectors each receiving an input image such as digital video and projecting an image based on the input image. A beam splitter with first and second surfaces is positioned such that the projected images strike the first surface and a portion (e.g., 50 to 95 percent) is transmitted through the beam splitter toward a screen with a retroreflective surface. The retroreflective surface reflects the splitter-transmitted portion back along the same path but with increased brightness. The light reflected from the retroreflective surface strikes the second surface of the beam splitter and is reflected toward a display viewing zone provided at about the focal points of the reflected projectors. A 3D image is perceivable to a viewer who positions his eyes at or near any of two or more viewing locations proximate to the projection surface.
