Die Anzahl zu animierender Objekte ist in komplexen Modellen zu groß, um alle Animationen flüssig darzustellen. Dynamisch abgestuft wählt das entwickelte Verfahren gezielt wichtige Animationen aus, weniger relevante Animationen werden entsprechend seltener animiert. Die Selektion der Animationen erfolgt nach der projizierten Größe der Objekte auf das Ausgabegerät, um einen guten optischen Eindruck beizubehalten. Angepasst an die Leistungsfähigkeit des Rechners wird das Verfahren so geregelt, dass die Visualisierung einer hohen Anzahl von Objekten in Echtzeit möglich bleibt. Das Verfahren ist in einem Editor prototypisch implementiert, mit dem Schlüsselbilder für Objekte erzeugt werden können. Das Gruppieren von Objekten wird erlaubt, so dass eine Hierarchie von Bewegungspfaden definierbar ist. Die Evaluierung der Methode wird mittels Testszenen durchgeführt, die aus mehreren zehntausend animierten Objekten bestehen.}}, author = {{Laroque, Christoph and Fischer, Matthias and Eikel, Benjamin}}, booktitle = {{Augmented & Virtual Reality in der Produktentstehung}}, pages = {{193----206}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Regelung von Animationen in Simulationen von hochdynamischen Fabrikszenen }}}, volume = {{232}}, year = {{2008}}, } @article{4554, abstract = {{We have investigated the properties of neutral and charged excitons in single CdSe/ZnSe QD photodiodes by μ-photoluminescence spectroscopy.
