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":[{"first_name":"Christoph","last_name":"Laroque","full_name":"Laroque, Christoph"},{"first_name":"Matthias","last_name":"Fischer","full_name":"Fischer, Matthias","id":"146"},{"first_name":"Benjamin","last_name":"Eikel","full_name":"Eikel, Benjamin"}],"date_created":"2020-08-24T07:56:43Z","volume":232,"date_updated":"2022-01-06T06:53:26Z","publisher":"Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn","title":"Regelung von Animationen in Simulationen von  hochdynamischen Fabrikszenen ","citation":{"ama":"Laroque C, Fischer M, Eikel B.

Furthermore products and the corresponding manufacturing processes get more and more complex. Therefore, companies need new methods for the planning of manufacturing systems. One promising approach in this context is digital factory/virtual production—the modeling and analysis of computer models of the planned factory with the objective to reduce time and costs. For the modeling and analysis various simulation methods and programs have been developed. They are a highly valuable support for planning and visualizing the manufacturing system. But there is one major disadvantage: only experienced and long trained experts are able to operate with these programs. The graphical user interface is very complex and not intuitive to use. This results in an extensive and error-prone modeling of complex simulation models and a time-consuming interpretation of the simulation results.\r\n\r\nTo overcome these weak points, intuitive and understandable man–machine interfaces like augmented and virtual reality can be used. This paper describes the architecture of a system which uses the technologies of augmented and virtual reality to support the planning process of complex manufacturing systems. The proposed system assists the user in modeling, the validation of the simulation model, and the subsequent optimization of the production system. A general application of the VR- and AR-technologies and of the simulation is realized by the development of appropriate linking and integration mechanisms. For the visualization of the arising 3D-data within the VR- and AR-environments, a dedicated 3D-rendering library is used."}],"publication":"Computers in Industry","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"63"}],"user_id":"15415","_id":"17414"},{"publication_status":"published","publication_identifier":{"isbn":["0780395190"]},"year":"2005","citation":{"apa":"Fischer, M., Mueck, B., Mahajan, K., Kortenjan, M., Laroque, C., &#38; Dangelmaier, W.

Furthermore, it allows interactive rendering of substantially more complex scenes by instantiating objects.\r\n\r\nThe sampling process is done in the preprocessing. There, the polygons are randomly distributed in our hierarchical data structure, the randomized sample tree. This tree only uses space that is linear in the number of polygons. In order to produce an approximate image of the scene, the tree is traversed and polygons stored in the visited nodes are rendered. During the interactive walkthrough, parts of the sample tree are loaded from local or remote hard disk.\r\n\r\nWe implemented our algorithm in a prototypical walkthrough system.

Aus dieser Entwicklung resultieren hohe Anforderungen an die Gestaltung der Fertigungsprozesse. Im Wesentlichen kommt es darauf an, die Fertigungsprozesse möglichst rasch an die neuen Gegebenheiten anzupassen, bzw. neue Fertigungsprozesse so zu planen, dass sie auf Anhieb die erforderlichen Resultate bringen.\r\nEin wichtiges Mittel hierfür der Einsatz von Materialflusssimulationen. Hierzu ist zunächst die Erstellung eines Simulationsmodells notwendig. Dafür wird in einem ersten Schritt das zu betrachtende System analysiert und ein rechnerinternes Modell erzeugt. Dieses beinhaltet die Modellierung von Funktionen, Prozessen, Verhaltensweisen oder Regeln, die im Modell die tatsächlichen Wirkzusammenhänge im Unternehmen widerspiegeln sollen. Die so modellierten Aspekte sind untereinander so vernetzt, dass alle Funktionen des Modells ein Ganzes ergeben. Für viele Fragenstellungen werden umfangreiche Modelle mit einem komplexen Verhalten benötigt. Andererseits steigt mit zunehmender Größe und Komplexität des Simulationsmodells auch der Modellierungsaufwand, die Fehleranfälligkeit, die Laufzeit und der Interpretationsaufwand bei der Ergebnisauswertung. Fehler bei der Modellbildung führen bei der Simulation zu Fehlinterpretationen und falschen Ergebnissen.\r\nEinen wesentlichen Anteil daran hat die Gestaltung der Benutzungsschnittstelle: Das übliche, wenig intuitive WIMP-Interface (Windows, Icons, Mouse, Pointer) erfordert sehr gut geschulte Benutzer, sodass die Erzeugung der meist komplexen Simulationsmodelle mit großen Zeitaufwand verbunden ist. Die Präsentation der Simulationsergebnisse erfolgt in Form von Wertetabellen und zweidimensionalen, abstrakten Darstellungen des Fertigungssystems. Für die Simulationsexperten erscheint dies ausreichend, für ein aus verschiedenen Bereichen und Disziplinen zusammengesetztes Planungsteam ist das aber nicht akzeptabel. So können Fehlinterpretationen aufgrund der unklaren Darstellungen auftreten.\r\nDurch eine durchgängige Unterstützung von der Modellierung über die Ausführung bis zur Analyse von Simulationen durch Augmented-Reality und Virtual-Reality werden viele dieser Probleme überwunden aber viele neue Probleme entstehen.\r\nMarktgängige Simulatoren unterstützen zwar z.T. schon Virtual Reality; eine durchgängige Simulationsunterstützung wird aber in der Virtuellen Umgebung nicht geboten. Argumented Reality-Komponenten sind bisher nicht bekannt.\r\nIn diesem Artikel werden nach einer Analyse der benötigten Technologien die Nutzenpotentiale insb. durch den Einsatz von AR ausgelotet.\r\n","lang":"eng"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_name":"hni-id-1445.pdf","file_id":"18368","file_size":221846,"date_created":"2020-08-26T12:52:18Z","creator":"koala","date_updated":"2020-08-26T12:52:18Z"}],"ddc":["000"],"language":[{"iso":"eng"}]},{"abstract":[{"lang":"ger","text":"Simulation und Visualisierung sind anerkannte Mittel zum Verstehen und Analysieren von Fertigungsprozessen.

Der Benutzer wird sich in einer virtuellen 3D-Umgebung (Walkthrough-System) bewegen können und automatisch ermittelte Indizien für signifikante Abläufe erhalten. Zugleich soll die Simulation signifikante Objekte genauer simulieren. Bekundet der Benutzer Interesse an einem signifikanten Prozess, wird er automatisch zu dem jeweiligen Ort geführt werden und dort durch Eingriffe in die Simulation die kritische Situation experimentell untersuchen können. Da der kritische Moment in der Vergangenheit liegt und somit vom Betrachter schon verpasst ist, wird es dem Betrachter möglich sein, die Simulation auf einen Zeitpunkt vor dem Eintreten zurück zu setzen.\r\nDie virtuelle Szene (3D-Grafik-Modelle) einer typischen dynamischen Simulationsumgebung ist in der Regel zu komplex, um sie in Echtzeit in einem Walkthrough-System zu visualisieren und darzustellen.

For this purpose, tools for visualising are already implemented in prevalent simulation systems. The user creates his simulation model and generates a 3-dimensional (2,5-dimensional) visualising by means of the simulation system. This helps examining the process which makes it easier for the viewer to “understand” it. Simulation tools usually only provide the opportunity for a unidirectional visualising. In a 3-dimensional surrounding the viewer can not implement an interaction with the simulation while the system is running. Though an interaction during the simulation run enables the user to gain a better understanding of causal cohesions. Solutions via HLA are sophisticated and therefore rather suited for extensive projects.\r\nWe present a distributed system consisting of a commercial manufacturing simulation tool, a coupling module and a walkthrough system. The distributed system in conjunctions with the coupling module guarantees generality and a wide field of applications of the walkthrough system. Further it guarantees flexibility and selection of the specialized graphics hardware for the walkthrough system.

Furthermore, it allows interactive rendering of substantially more complex scenes by instantiating objects.\r\n\r\nFor the computation of an approximate image of the scene, a sampling technique is used. In the preprocessing, a so-called sample tree is built whose nodes contain randomly selected polygons from the scene. This tree only uses space that is linear in the number of polygons. In order to produce an image of the scene, the tree is traversed and polygons stored in the visited nodes are rendered. During the interactive walkthrough, parts of the sample tree are loaded from local or remote hard disk.\r\n\r\nWe implemented our algorithm in a prototypical walkthrough system.
