Claim One:
1. A method for computing holographic encoding values for an optical light modulator of a holographic system for the reconstruction of three-dimensional scenes, which include objects with transparent properties, for at least one observer eye, where the three-dimensional scene is divided into individual object points and the coordinates of these object points are determined, a virtual observer position is determined which corresponds with the position of a selected observer eye where the three-dimensional scene is apparently perceived, all object points to be encoded are determined which are not fully covered by other object points seen from the virtual observer position, all visible object points to be encoded which are seen at the same angle from the virtual observer position are sorted by their distance to the virtual observer position, the actual brightness of each visible object point is determined, with or without considering the location and intensity of all real and virtual light sources of the scene at the position of those object points at the angle at which they are seen from the virtual observer position, where the physical properties of the objects including the real and virtual light sources can be taken into account, wherein: for each visible object point to be encoded an apparent brightness value with which the object point is perceived at the virtual observer position is determined considering its actual brightness at its actual position, the distance to the virtual observer position and the transparency properties of all objects or object points which are situated between that visible object point and the virtual observer position, and that each object point is encoded separately with its respective brightness value such that it is reconstructed in the holographic system as far as possible at its position with that brightness value, so that opaque and transparent object points can be perceived separately at their respective positions.
