The invention relates to a method for reconstructing a 3D scene made of object points in a holographic display, wherein the reconstruction is visible from a visibility region. The aim of the invention is to realize visibility and/or covering of parts of the 3D scene corresponding to the real parameters, with the reconstruction, for a viewer from every place of the visibility region. When the hologram is calculated, a method is used that takes the visibility into consideration by means of a visibility function. According to the method, processor means generate a spatial point matrix for defining the positions of individual object points, which are assigned predetermined intensity and phase values. Within the visibility region, a complex-value wave front for each single object point is calculated. The intensity values of the object points are multiplied with the associated visibility function, in order to determine a common modified wave front of the object points, which is transformed into the plane of a light modulator in order to calculate modified control values for the object points. Control means generate corresponding control signals for encoding said control values of the CGH in the light modulator. |
