Title:
METHOD AND DEVICE FOR ENCODING THREE-DIMENSIONAL SCENES WHICH INCLUDE TRANSPARENT OBJECTS IN A HOLOGRAPHIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/121130
Kind Code:
A3
Abstract:
Method for computing the code for the reconstruction of three-dimensional scenes (200,300) which include objects (300) which partly absorb light or sound. The method can be implemented in a computing unit. In order to reconstruct a three-dimensional scene as realistic as possible, the diffraction patterns are computed separately at their point of origin considering the instances of absorption in the scene. The method can be used for the representation of three-dimensional scenes in a holographic display or volumetric display. Further, it can be carried out to achieve a reconstruction of sound fields in an array of sound sources.
