Abstract:
1. A 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, comprising: defining a sub-hologram, together with each object point of the scene to be reconstructed with the visibility region; forming the entire hologram using 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; where 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.
