ABSTRACT:
A method for fabricating a computer generated hologram or holographic stereogram can reconstruct a three-dimensional object having visualized cross-sectional surfaces, wherein three-dimensional object composed only of surface data is processed to have visualized cross-sectional surfaces on a given cross section thereof by adding surface data to cross-sectional surfaces. The method includes obtaining volume data of a three-dimensional object, obtaining a number of two-dimensional cross-sectional image data of the three-dimensional object, producing three-dimensional object image data composed only of surface data of the three-dimensional object from the two-dimensional cross-sectional data obtained above, cutting the three-dimensional object surface data along predetermined cross section, defining the shape by adding surface data representing cross-sectional surfaces on the cut cross section, defining the arrangement of the defined three-dimensional object, a hologram plan and a reference beam to compute interference fringes on the hologram plane, and recording the interference fringes on a recording medium.
