Definitions

  • the present invention relates to the field of mosaic type structures, and relates more particularly to a set of individual elements intended to form, once assembled to each other, a mosaic type structure, on a mosaic type structure formed by a such set of individual elements, on a method of making such a mosaic type structure, on a computer program product for the implementation of this method and on a decoration installation incorporating the mosaic type structure.
  • mosaic refers to any juxtaposition of pieces or elements, identical or different, so as to form an integral structure having an outer surface bearing a decoration reproducing at least one given image when a person observing the outer surface is in a given position.

  • the outer surface of the mosaic-like structure, which carries the decor may not be flat.
  • One of these techniques is to reproduce an image with a decoration consisting of grooves carved in a surface of a generally white panel. These furrows, generally all hollowed out in the same direction of the panel and therefore parallel to each other, create dark areas of shadow, in contrast with the white color of the unetched surface parts.

  • This technique has the advantage of allowing to obtain a panel with a decoration reproducing an image pleasing to the eye and may appear atypical insofar as it appears only in a given position of the observer.
  • each individual element carries a part of the decoration reproducing a part of the overall image thanks to the luminance difference, and thus to the contrast, between different zones of the individual element.
  • the use of individual elements that are assembled can also provide a visual effect similar to that produced by a mosaic and is pleasing to the eye.

    - Ausführen eines Algorithmus an einem Ausgangsbild, wobei der Algorithmus in Abhängigkeit von den einzelnen Elementen (1, 4, 7) des Satzes aus einzelnen Elementen das Ausgangsbild derart in Bildabschnitte zerlegt, dass die Graustufe oder Graustufen in jedem Bildabschnitt dem Gestaltungsabschnitt von mindestens einem einzelnen Element (1, 4, 7) entspricht bzw. entsprechen, wobei die Bildabschnitte, deren Graustufe oder Graustufen nicht dem Gestaltungsabschnitt von mindestens einem einzelnen Element (1, 4, 7) entspricht bzw. entsprechen, iterativ in Bildabschnitte mit kleineren Abmessungen zerlegt werden, bis die Graustufe oder Graustufen jedes Bildabschnitts mindestens einem einzelnen Element (1, 4, 7) des Satzes entspricht bzw. entsprechen; und
    - Aufbauen der mosaikartigen Struktur aus den einzelnen Elementen (1, 4, 7), die einen Gestaltungsabschnitt tragen, der ein Gebilde oder Gebilde (2, 6, 9) aufweist, die einen Bereich mit einer Leuchtdichte erzeugt bzw. erzeugen, die den Graustufen der Bildabschnitte entspricht, sodass eine mosaikartige Struktur erhalten wird, die eine Gestaltung trägt, die das Ausgangsbild wiedergibt.
  13. Verfahren nach Anspruch 12, dadurch gekennzeichnet, dass es ferner nach dem Ausführen des Algorithmus und vor dem Schritt des Aufbauens der mosaikartigen Struktur ferner einen Schritt zum rechnergestützten Simulieren der endgültigen mosaikartigen Struktur und gegebenenfalls einen Schritt umfasst, der darin besteht, den Algorithmus nach der Abänderung des Satzes aus einzelnen verfügbaren Elementen (1, 4, 7) durch den Nutzer erneut auszuführen.
  14. Computerprogrammprodukt, das einen ausführbaren Code zum Ausführen des Algorithmus des Verfahrens nach Anspruch 12 und zum Durchführen des Schritts zum Simulieren der endgültigen mosaikartigen Struktur und des Schritts zum erneuten Ausführen des Algorithmus des Verfahrens nach Anspruch 13 speichert.
  15. Gestaltungseinrichtung, dadurch gekennzeichnet, dass sie eine mosaikartige Struktur nach Anspruch 11 und eine Beleuchtungsquelle umfasst, die so angeordnet ist, dass sie die mosaikartige Struktur insbesondere veränderlich beleuchtet, entweder durch Bewegen der Beleuchtungsquelle oder durch Verändern der Intensität der Beleuchtung der Struktur oder mit einer Kombination aus beidem.
