Method and apparatus for providing volumetric projection

摘要

An apparatus displays an image Ä140Ü in three-dimensional virtual space in a form that may be modified by a user using an interface device Ä500Ü. The apparatus divides computer-generated data representing 3D images into data subsets representing two-dimensional slices of the 3D image. The apparatus displays each image slice on a layer in a stack of liquid crystal displays (LCD) Ä210-219Ü. The stack sequentially displays the layers of the image at a fast rate to appear as a single 3D -image Ä140Ü. Each layer in the stack has a dedicated driver and memory. The apparatus includes a reflector Ä400Ü for reflecting the 3D image in a manner so as to produce a virtual image in unsurrounded space capable of being viewed from every direction. Spectators may use a user interface device Ä500Ü to touch or manipulate the virtual image. The user interface device Ä500Ü transmits data to the apparatus, which generates data to modify the virtual image. <IMAGE>
