The special feature of our approach is that it allows an interactive navigation in very large scenes (30 GB/400 million polygons in our benchmark scenes) that cannot be stored in main memory, but only on a local or remote hard disk. 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" author: - first_name: Matthias full_name: Fischer, Matthias id: '146' last_name: Fischer - first_name: Michael full_name: Grafe, Michael last_name: Grafe - first_name: Carsten full_name: Matysczok, Carsten last_name: Matysczok - first_name: Bengt full_name: Mueck, Bengt last_name: Mueck - first_name: Michael full_name: Schoo, Michael last_name: Schoo citation: ama: 'Fischer M, Grafe M, Matysczok C, Mueck B, Schoo M.

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 \x93understand\x94 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. A further contribution of this paper is the solution of the time synchronisation problem caused by simulation tool and walkthrough system.\r\n" author: - first_name: Bengt full_name: Mueck, Bengt last_name: Mueck - first_name: Wilhelm full_name: Dangelmaier, Wilhelm last_name: Dangelmaier - first_name: Matthias full_name: Fischer, Matthias id: '146' last_name: Fischer - first_name: Wolfram full_name: Klemisch, Wolfram last_name: Klemisch citation: ama: 'Mueck B, Dangelmaier W, Fischer M, Klemisch W.

The special feature of our approach is that it allows an interactive navigation in very large scenes (30 GB/400 million polygons in our benchmark scenes) that cannot be stored in main memory, but only on a local or remote hard disk. 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.

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.

It renders an image of an arbitrary three-dimensional scene consisting of triangular primitives by reconstruction from a dynamically chosen set of random surface sample points. This approach is independent of mesh connectivity and topology. The resulting rendering time grows only logarithmically with the numbers of triangles in the scene. We were able to render walkthroughs of scenes of up to 10^14 triangles at interactive frame rates. Automatic identification of low detail scene components ensures that the rendering speed of the randomized z-buffer cannot drop below that of conventional z-buffer rendering. Experimental and analytical evidence is given that the image quality is comparable to that of common approaches like z-buffer rendering. The precomputed data structures employed by the randomized z-buffer allow for interactive dynamic updates of the scene. Their memory requirements grow only linearly with the number of triangles and allow for a scene graph based instantiation scheme to further reduce memory consumption. author: - first_name: Michael full_name: Wand, Michael last_name: Wand - first_name: Matthias full_name: Fischer, Matthias id: '146' last_name: Fischer - first_name: Ingmar full_name: Peter, Ingmar last_name: Peter - first_name: Friedhelm full_name: Meyer auf der Heide, Friedhelm id: '15523' last_name: Meyer auf der Heide - first_name: Wolfgang full_name: Straßer, Wolfgang last_name: Straßer citation: ama: 'Wand M, Fischer M, Peter I, Meyer auf der Heide F, Straßer W.

We consider arbitrarily large scenes consisting of unit size balls. For a smooth navigation in the scene we have to fulfill hard real time requirements. Therefore, we need algorithms whose running time is independent of the total number of objects in the scene and that use as small space as possible. In this work we focus on one of the basic operations in our walkthrough system: reporting the objects around the visitor within a certain distance. Previously a randomized data structure was presented that supports reporting the balls around the visitor in an output sensitive time and allows insertion and deletion of objects nearly as fast as searching. These results were achieved by exploiting the fact that the visitor moves ''slowly'' through the scene. A serious disadvantage of the aforementioned data structure is a big space overhead and the use of randomization. Our first result is a construction of weak spanners that leads to an improvement of the space requirement of the previously known data structures. Then we develop a deterministic data structure for the searching problem in which insertion of objects are allowed. Our incremental data structure supports O(1+k) reporting time, where k is a certain quantity close to the number of reported objects. The insertion time is similar to the reporting time and the space is linear to the total number of objects.\r\n" author: - first_name: Matthias full_name: Fischer, Matthias id: '146' last_name: Fischer - first_name: Tamás full_name: Lukovszki, Tamás last_name: Lukovszki - first_name: Martin full_name: Ziegler, Martin last_name: Ziegler citation: ama: 'Fischer M, Lukovszki T, Ziegler M.

The scene may be arbitrarily large and has to be stored in secondary memory (discs) with relatively slow access. We allow a visitor to walk in the scene, and a modeler to update the scene by insertions and deletions of balls. We focus on the realtime requirement of animation systems: For some t (specified by the computation power of (the rendering hardware of) the graphic workstation) the data structure has to guarantee that the balls within distance t of the current visitor's position are presented to the rendering hardware, 20 times per second. Insertions and deletions should also be available to the visitor with small delay, independent of the size of the scene. We present a data structure that fulfills the above task in realtime. Its runtime is output-sensitive, i.e. linear in a quantity close to the output size of the query. We further present (preliminary) experimental results indicating that our structure is efficient in practice.\r\n" author: - first_name: Matthias full_name: Fischer, Matthias id: '146' last_name: Fischer - first_name: Friedhelm full_name: Meyer auf der Heide, Friedhelm id: '15523' last_name: Meyer auf der Heide - first_name: Willy-Bernhard full_name: Strothmann, Willy-Bernhard last_name: Strothmann citation: ama: 'Fischer M, Meyer auf der Heide F, Strothmann W-B.
