Abstract:
1. A fabrication method for a computer-generated hologram in which a three-dimensional object having visualized cross-sectional surfaces is recorded, including: a step of obtaining volume data of the three-dimensional object; a step of producing three-dimensional image data composed only of surface data of the three-dimensional object from the volume data obtained in the above step; a step of cutting the three-dimensional image data composed only of the surface data, produced in the above step, along a predetermined cross section; a step of defining the shape of the three-dimensional object to be recorded in a hologram by adding polygon surface data representing cross-sectional surfaces on the cut cross section to the same; a step of defining the arrangement of the three-dimensional object defined in the above step, a hologram plane, and a reference beam to compute interference fringes on the hologram plane; and a step of recording the interference fringes computed in the above step onto a recording medium.
