Abstract
Two computer-generated display macro holograms (CGDMH) have been synthesized to demonstrate the possibility of holographic display of 3D objects given by their mathematical descriptions only. Three dimensional models of the objects and shaded 2D projections in varying viewing directions were generated using the methods of computer graphics. For each projection, a Fourier hologram was synthesized and encoded by the kinoform method. The recording of the obtained digital kinoforms on a commercially available photographic film was done by a computer controlled laser device. This process produces, after film development and bleaching, a facet CGDMH. The complete CGDMHs have a size of 672 X 672 mm2 and consist of 900 elementary holograms of 256 X 256 samples each, calculated for different directions within the solid angle of +/- 90 degree(s). They allow the visual representation of 3D objects with good quality.
