Method for Rendering and Generating Color Video Holograms in Real Time

Method for rendering and generating colour video holograms for a holographic display device with at least one light modulator means on which a scene which is divided into object points is encoded as an entire hologram and which can be seen as a reconstruction from a visibility region which lies within one periodicity interval of the reconstruction of the video hologram, where the visibility region defines a sub-hologram together with each object point of the scene to be reconstructed, and where the entire hologram is formed by way of a superimposition of sub-holograms, where a 3D rendering graphics pipeline structures a scene, which is represented by image data with depth information, into object points, and determines and provides at least colour and depth information for the object points, wherein one holographic colour pipeline for each primary colour generates colour-related hologram values in that for each visible object point the complex hologram values of the sub-hologram can be retrieved from at least one look-up table, or are determined analytically from the wave front of the object point to be reconstructed in a modulator region of the light modulator means, and where the holographic colour pipelines execute the computation of the respective, superimposed entire holograms in parallel.
