A method for rendering and generating computer-generated video holograms from image data with depth information in real-time, wherein, in a first mode, a 3D rendering-graphics pipeline (3DLP) converts a scene to raster image data as a 2D projection of said scene and generates pixel values for the controllable pixels of a monitor, characterized in that the pipeline can be extended in a switchable fashion and that complex hologram values are generated in a second mode in at least one holographic graphics pipeline (HPL), and the coding for a light modulator means of a holographic playback device as pixel values takes place in said pipeline, thereby modulating an incident wave field simultaneously or alternatively for standard graphical representation by operating the light modulator with the coded hologram values in such a way that the desired scene is reconstructed by interference in the space. The invention permits the optional, and even parallel, operation of a conventional monitor and holographic playback device, thereby insuring compatibility with existing industry standards. The invention also ensures an important technical and economic acceptance of recent technology of holographic representation. |
