Abstract	This paper reports a novel concept known as “Holo-graphics”, a term that is an amalgamation of “hologram” and “computer graphics”. The idea is to explore a method whereby traditional computer graphic techniques can be applied in synthesizing holograms of complicated object scenes. The need of such a technology, apparently, is to reduce the heavy computation that is required to generate a hologram directly from a three dimensional (3-D) image. In the proposed method, a hologram is back projected onto a hypothetical plane known as the Virtual Diffraction Plane (VDP) that is located at close proximity to the object space. Groups of diffraction fringes, each corresponding to an item represented by the hologram, are extracted to form the HG models. Subsequently, HG models obtained from one or more holograms are modified, and integrated onto a VDP canvas to synthesize a targeted object scene. The resulting complex image on the VDP canvas is then converted to a hologram.Relation between the object space, the virtual diffraction plane P, and the hologram .
