Abstract: A multi-planar volumetric display system and method of operation generate volumetric three-dimensional images using a multi-surface optical device including a plurality of individual optical elements arranged in an array; an image projector for selectively projecting images on respective optical elements to generate a first volumetric three-dimensional image viewable in the multi-surface optical device; and a floating-image generator for projecting the first volumetric three-dimensional image to generate a second volumetric three-dimensional image viewable as floating in space at a location separate from the multi-surface optical device. Anti-aliasing adjusts the display of voxels in a transition between optical elements, such that color values of the voxels are modified as a function of the distance of the voxels from the optical elements, to generate a smooth transition between portions of the volumetric three-dimensional image.

Abstract: Image compositing apparatus and methodology for the creation, in a defined volume of three-dimensional space, of a composite organization of plural images/visual phenomena, including at least one projected real image, displayed in formats including (a) front-to-rear, (b) side-by-side and (c) overlapping and intersecting, adjacency. The apparatus incorporates different unique arrangements of visual sources, and optical elements including concave reflectors, beam splitters and image-forming/image-transmissive scrim/screen structures. In one important modification of the system, which does not necessarily require compositing, a projected real image is derived from an image-producing data stream containing three-dimensional image cues selected from the group consisting of shading, occlusion, perspective, motion parallax, size vs. depth, light (chroma value) vs. depth and definition vs. depth.

Abstract: A method and apparatus for projecting images, advertisements and the like to passengers of moving vehicles. A projector is placed on the vehicle and it projects an image on the walls of a train tunnel, clouds near an airplane, etc. as the vehicle moves. A technique is provided for correcting distortion caused by the positional changes between the vehicle and the projection surface.
