Abstract
The volumetric 3D display system of this invention applies a moving display panel that sweeps a display space. The full volume swept by the active screen is used as display space. A 3D image to be displayed is first processed into slices of image data based on an orthogonal 3D grid structure. The slice data are then converted into image frames to be displayed on the active screen by mapping the location indices in the orthogonal 3D grid to the location indices on the moving screen. The preferred method of displaying an image frame is to convert each image frame into a number of 'image shots' and then display those image shots in sequence. An image shot comprises a number of simple orthogonal patterns aligned in vertical or horizontal directions. Combination of a number of image shots approximates the corresponding image frame.
