description The invention concerns a method which consists in computing (E1-E4), in a three-dimensional geometric space, a set of two-dimensional images representing a virtual object from different respective viewpoints. The virtual object is represented by digital data stored in a computer. The holograms are computed (E5-E6) for the two-dimensional images respectively by a complex transform, such as a Fourier transform technique. The holograms are then juxtaposed (E7) to form a digital hologram of the object, which is physically reproduced (E8) by a light spatial modulator. By illuminating the light spatial modulator with a coherent source, a three-dimensional image of the object is obtained.
