Multiview three-dimensional (3-D) displays offer viewing of high-resolution stereoscopic images from arbitrary positions without glasses. Such displays consist of view-dependent pixels that reveal a different color according to the viewing angle. Therefore, the left and right eye of an observer see slightly different images on the screen. This leads to the perception of 3-D depth and parallax effects when the observer moves. Although the basic optical principles of multiview auto-stereoscopy have been known for over a century [21], only recently displays with increased resolution, or systems based on multiple projectors, have made this approach practical. Today, commercial availability ranges from multiview desktop monitors [19] to large-scale displays based on multiprojector systems [1], [11].
