Abstract
A method of spatial visualization in which several views are decomposed into bits of partial information, which are made optically visible by image rendering elements. Neighboring image rendering elements emit light of different wavelengths or wavelength ranges. Propagation directions for the light are given by wavelength filters such that an observer will see predominantly bits of partial information of a first selection of views with one eye and predominantly bits of partial information of a second selection with the other eye. At least one image rendering element is simultaneously allocated bits of partial information from at least two different views. The allocation is made in such a way that the wavelength of the partial information is always equal to the wavelength, or lies in the wavelength range, of the light emitted by the allocated image rendering element.
