1. An image display system for simultaneously displaying a plurality of images of a three-dimensional object formed from a plurality of viewing directions, said image display system comprising:

  • a three-dimensional display surface having a generally concave geometry, at least first and second display surface regions in spatially contiguous relation to each other, and a volumetric extent for defining a three-dimensional display volume extending in the direction of the concavity of said three-dimensional display surface and a three-dimensional viewing zone spatially encompassed within said three-dimensional display volume;

    first image signal generation means for generating a first signal representative of a first image of said three-dimensional object viewed along a first viewing direction;

    second image signal generation means for generating a second signal representative of a second image of said three-dimensional object viewed along a second viewing direction;

    first image producing means, disposed within said three-dimensional display volume and responsive to said first signal, for generating said first image and projecting said first image onto said first display surface region such that light rays emanating from said first image producing means towards said first display surface region are generally restricted from said three-dimensional viewing zone;

    second image producing means, disposed within said three-dimensional display volume and responsive to said second signal, for generating said second image and projecting said second image onto said second display surface region such that light rays emanating from said second image producing means towards said second display surface region are generally restricted from said three-dimensional viewing zone;

    whereby a viewer whose eyes are disposed within said three-dimensional viewing zone is free to view said first and second projected images from anywhere within said three-dimensional viewing zone with a field of view of at least 180 degrees.
