摘要： PCT No. PCT/NZ96/00028 Sec. 371 Date Feb. 2, 1998 Sec. 102(e) Date Feb. 2, 1998 PCT Filed Apr. 4, 1996 PCT Pub. No. WO96/31986 PCT Pub. Date Oct. 10, 1996The present invention relates to improvements in a three-dimensional display system. A transformation technique is described wherein deflection coordinates defining the spatial locations of the images written into the display volume are determined by transformation from a coordinate system based on the display volume to a coordinate system based on the one or more electron guns. The application further relates to a technique by which the location of an electron beam within the display volume may be determined. These techniques involve positioning conductive material at various locations such as the screen and the enclosure of the display itself so that the impinging electron beam may be detected and thy the location of the beam in the display volume may be derived. Image enhancing techniques are described in conjunction with the location techniques whereby conductive films are evaporated onto the screen and/or the enclosure. Modifications in voxel plotting techniques are described so as to enhance the quality of the image produced in the display volume. The technique includes interlacing the scanned print location. An additional improvement is provided by a particular conduction medium configuration superimposed or deposited onto the screen where the conducting medium incorporates information which is extracted or read from the medium by scanning a particle beam across its face so as to invoke momentary voltages or currents in the conducting medium.

摘要： In a cylindrical coordinate system, the dominant direction of a line changes in a predictable manner. A rasterizer uses this fact to efficiently render a desired line on a volumetric display. It does do by determining whether first and second points on the desired line are on first and second constituent line-segments of the desired line, the first and second constituent line-segments having different dominant directions. On the basis of the determination, the rasterizer renders a second voxel representative of the second point on the desired line by incrementally proceeding from a first voxel representative of the first point. The location of the second voxel is selected to minimize a distance between that second voxel and the desired line.

摘要： The invention features a spinning screen assembly that incorporates a thin projection screen held in place by a hollow transparent mount. The amount may be spherical in overall shape. A projection system projects portions of a 3-D image onto the projection screen. A control electronics subsystem coordinates other subsystems, including the projection system and a source of image data. Persistence of vision causes viewer to perceive a volumetric image from a series of projections. The thinness of the projection screen reduces visual dead zones. Enclosing the projection screen within the screen assembly reduces the air resistance that the thin screen is exposed to during rotation. In a further embodiment, a stationayry hemispherical transparent dome covers the spinning screen assembly.

摘要： The method for producing media content that reproduces a three-dimensional object as an image appearing three-dimensionally in association with a display device includes capturing a plurality of images of a three-dimensional object with a plurality of cameras positioned at different angles. At least three of the images are synchronized to be reproduced in association with the display device. Then, a computer system assigns at least three synchronized images to the display device viewable from at least three different perspectives to visually replicate the three-dimensional object as captured by at least three cameras at at least three different angles such that the image appears three-dimensional when moving among the at least three perspectives as if moving around the three-dimensional object itself.

摘要： A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

摘要： This invention relates generally to new and improved approaches for displaying volumnetric three-dimensional (3D) images. The basic idea features new optical-mechanical mechanisms enabling creation of volumetric 3D images by successive projection of whole frames of 2D images. This new method projects a series of frames of 2D images, through an optical-mechanical image delivery system, onto a translucent screen which moves periodically and sweeps a space. As viewed from outside the space, the series of 2D images distributed in the space form a volumetric image because of the after-image effect of human eyes. Many viewers can walk around the space and see the image from omni-directions simultaneously without wearing any kind of glasses.

摘要： A system for generating three dimensional images includes a data processor which generates a first data stream representing coordinates along a first axis, a second data stream representing coordinates along a second axis, and a third data stream representing intensities of optical beams. A demultiplexer transforms the first, second, and third data streams into multiple control signals each comprised of elements of the first, second and third data streams. The system further includes an optical energy source for generating an optical signal, and an optical beam steering system which divides the optical signal into multiple optical beams which are individually deflected and intensity modulated under the control of one of the control signals. The optical beams then are recombined and steered to reflect off the reflecting surface of a reflective structure, resulting in the presentation of a 3D image.
