  text: Viele virtuelle 3-D-Szenen im industriellen Bereich sind nicht gleichmäßig
    strukturiert, z.B. weil sie eine stark unterschiedliche Dichteverteilung der Polygone
    aufweisen. Für solch heterogene Daten existiert kein Algorithmus, der die Gesamtheit
    der Daten sowohl schnell als auch mit guter Qualität darstellen kann. Die Auswahl
    der richtigen Algorithmen für einzelne Szenenteile durch einen Experten ist zeitintensiv
    und in vielen Visualisierungssystemen nicht umzusetzen. Um dieses Problem zu lösen,
    setzt das hier vorgestellte Multi-Algorithmen-Rendering verschiedene Renderingalgorithmen
    gleichzeitig ein, um eine virtuelle 3-D-Szene darzustellen. Das Verfahren unterteilt
    die Szene dafür in einem Vorverarbeitungsschritt automatisch in geeignete Teilregionen
    und bestimmt deren Eigenschaften. Diese Daten werden zur Laufzeit dazu genutzt,
    um ständig für den aktuellen Standpunkt des Betrachters eine Abschätzung der Qualität
    und Laufzeit der zur Auswahl stehenden Renderingalgorithmen zu berechnen. Durch
    die Lösung eines Optimierungsproblems kann so bei vorgegebener Bildrate durch
    die passende Zuordnung der Algorithmen zu den Regionen die Bildqualität optimiert
    werden – bei automatischer Anpassung an die Leistungsfähigkeit der eingesetzten
    Hardware. In einer experimentellen Evaluierung vergleichen wir die Laufzeit und
    Bildqualität des Verfahrens mit denen verbreiteter Standardrenderingverfahren.

  text: Many 3D scenes (e.g. generated from CAD data) are composed of a multitude
    of objects that are nested in each other. A showroom, for instance, may contain
    multiple cars and every car has a gearbox with many gearwheels located inside.
    Because the objects occlude each other, only few are visible from outside. We
    present a new technique, Spherical Visibility Sampling (SVS), for real-time 3D
    rendering of such -- possibly highly complex -- scenes. SVS exploits the occlusion
    and annotates hierarchically structured objects with directional visibility information
    in a preprocessing step. For different directions, the directional visibility
    encodes which objects of a scene's region are visible from the outside of the
    regions' enclosing bounding sphere. Since there is no need to store a separate
    view space subdivision as in most techniques based on preprocessed visibility,
    a small memory footprint is achieved. Using the directional visibility information
    for an interactive walkthrough, the potentially visible objects can be retrieved
    very efficiently without the need for further visibility tests. Our evaluation
    shows that using SVS allows to preprocess complex 3D scenes fast and to visualize
    them in real time (e.g. a Power Plant model and five animated Boeing 777 models
    with billions of triangles). Because SVS does not require hardware support for
    occlusion culling during rendering, it is even applicable for rendering large
    scenes on mobile devices.

  text: "In order to evaluate the efficiency of algorithms for real-time 3D rendering,
    different properties like rendering time, occluded triangles, or image quality,
    need to be investigated. Since these properties depend on the position of the
    camera, usually some camera path is chosen, along which the measurements are performed.
    As those measurements cover only a small part of the scene, this approach hardly
    allows drawing conclusions regarding the algorithm's properties at arbitrary positions
    in the scene. The presented method allows the systematic and position-independent
    evaluation of rendering algorithms. It uses an adaptive sampling approach to approximate
    the distribution of a property (like rendering time) for all positions in the
    scene. This approximation can be visualized to produce an intuitive impression
    of the algorithm's behavior or be statistically analyzed for objectively rating
    and comparing algorithms. We demonstrate our method by evaluating performance
    aspects of a known occlusion culling algorithm.\r\n"

  text: "Many virtual 3D scenes, especially those that are large, are not structured
    evenly. For such heterogeneous data, there is no single algorithm that is able
    to render every scene type at each position fast and with the same high image
    quality. For a small set of scenes, this situation can be improved if different
    rendering algorithms are manually assigned to particular parts of the scene by
    an experienced user. We introduce the Multi-Algorithm-Rendering method. It automatically
    deploys different rendering algorithms simultaneously for a broad range of scene
    types. The method divides the scene into subregions and measures the behavior
    of different algorithms for each region in a preprocessing step. During runtime,
    this data is utilized to compute an estimate for the quality and running time
    of the available rendering algorithms from the observer's point of view. By solving
    an optimizing problem, the image quality can be optimized by an assignment of
    algorithms to regions while keeping the frame rate almost constant.\r\n"

  text: "We present a parallel rendering system for heterogeneous PC clusters to visualize
    massive models. One single, powerful visualization node is supported by a group
    of backend nodes with weak graphics performance. While the visualization node
    renders the visible objects, the backend nodes asynchronously perform visibility
    tests and supply the front end with visible scene objects. The visualization node
    stores only currently visible objects in its memory, while the scene is distributed
    among the backend nodes’ memory without redundancy. To efficiently compute the
    occlusion tests in spite of that each backend node stores only a fraction of the
    original geometry, we complete the scene by adding highly simplified versions
    of the objects stored on other nodes. We test our system with 15 backend nodes.
    It is able to render a ≈ 350,M polygons (≈ 8.5,GiB) large aircraft model with
    20, to 30,fps and thus allows a walk-through in real-time.\r\n"

  text: "Occlusion culling is a common approach to accelerate real-time rendering
    of polygonal 3D-scenes by reducing the rendering load. Especially for large scenes,
    it is necessary to remove occluded objects to achieve a frame rate that provides
    an interactive environment. In order to benefit from the culling properly, often
    hierarchical data structures are used. These data structures typically create
    a spatial subdivision of a given scene into axis-aligned bounding boxes. These
    boxes can be tested quickly, but they are not very precise. By using these boxes,
    the included objects are detected as visible, even if other objects occlude them
    (false-positives). To get perfect results, the models\x92 original geometry included
    in the box has to be tested, but this would require too much computational power.
    To overcome this problem, original objects\x92 approximations could be used, but
    typical methods for mesh simplification cannot be applied, because they do not
    create an outer hull for a given object. We present a model simplification algorithm,
    which generates simple outer hulls, consisting of only few more triangles than
    a box, while preserving an object\x92s shape better than a corresponding bounding
    box. This approach is then extended to a hierarchical data structure, the so-called
    hull tree, that can be generated for a given scene to improve the visibility tests.
    Next, we present an approximative rendering algorithm, which combines the features
    of the hull tree with the use of inner hulls for efficient occlusion detection
    and global state-sorting of the visible objects.\r\n"

  text: 'We present a parallel rendering system for PC-Clusters to visualize large
    3D scenes. One single visualization node, equipped with a high-end graphics adapter,
    is supported by a group of backend nodes with weak graphics performance. The objects
    of the scene are distributed among these backend nodes, they serve two purposes:
    First, they provide an out-of-core memory system for the visualization node. Second,
    they assist the visualization node''s rendering by performing visibility calculations
    and only sending visible objects to the visualization node. In order to obtain
    fast rendering with our system, we have to distribute the objects among the backend
    nodes in a way that does not only guarantee an even distribution of the objects,
    but also an even distribution of the visibility calculations and the amount of
    data send to the visualization node. We identify necessary properties of the distribution
    and argue that a random distribution is a good candidate. Further, in order to
    reduce the number of objects sent to the visualization node per frame, we employ
    an approximate hierarchical occlusion culling in each backend node. For this,
    they are equipped, in addition to the objects assigned to them, with simplified
    versions of the other objects of the 3D scene. The visualization node is equipped
    with 512 MiB video memory and supported by 15 backend nodes. This system is able
    to render a approx. 350 million polygons (approx. 8.5 GiB) large aircraft model
    between 20 - 30 fps and thus allows a walkthrough in real-time.'

  text: 'Gathering n mobile robots in one single point in the Euclidean plane is a
    widely studied problem from the area of robot formation problems. Classically,
    the robots are assumed to have no physical extent, and they are able to share
    a position with other robots. We drop these assumptions and investigate a similar
    problem for robots with (a spherical) extent: the goal is to gather the robots
    as close together as possible. More exactly, we want the robots to form a sphere
    with minimum radius around a predefined point. We propose an algorithm for this
    problem which synchronously moves the robots towards the center of the sphere
    unless they block each other. In this case, if possible, the robots spin around
    the center of the sphere. We analyze this algorithm experimentally in the plane.
    If R is the distance of the farthest robot to the center of the sphere, the simulations
    indicate a runtime which is linear in n and R. Additionally, we prove a theoretic
    upper bound for the runtime of O(nR) for a discrete version of the problem. Simulations
    also suggest a runtime of O(n + R) for the discrete version.'

  text: "Given a set of n mobile robots in the d-dimensional Euclidean space, the
    goal is to let them converge to a single not predefined point. The challenge is
    that the robots are limited in their capabilities. Robots can, upon activation,
    compute the positions of all other robots using an individual affine coordinate
    system. The robots are indistinguishable, oblivious and may have different affine
    coordinate systems. A very general discrete time model assumes that robots are
    activated in arbitrary order. Further, the computation of a new target point may
    happen much earlier than the movement, so that the movement is based on outdated
    information about other robot's positions. Time is measured as the number of rounds,
    where a round ends as soon as each robot has moved at least once. In [Cohen, Peleg:
    Convergence properties of gravitational algorithms in asynchronous robot systems],
    the Center of Gravity is considered as target function, convergence was proven,
    and the number of rounds needed for halving the diameter of the convex hull of
    the robot's positions was shown to be O(n^2) and Omega(n). We present an easy-to-check
    property of target functions that guarantee convergence and yields upper time
    bounds. This property intuitively says that when a robot computes a new target
    point, this point is significantly within the current axes aligned minimal box
    containing all robots. This property holds, e.g., for the above-mentioned target
    function, and improves the above O(n^2) to an asymptotically optimal O(n) upper
    bound. Our technique also yields a constant time bound for a target function that
    requires all robots having identical coordinate axes.\r\n"

  text: "Commercial software of material flow simulations has the ability to layout
    the simulated models. Arranged equipment, such as conveyors or machines, includes
    the need to model and determine motion paths for moving objects like forklifts
    or automatically guided vehicles, so that the simulation framework is able to
    navigate all vehicles across those motion paths. After analyzing first scenarios,
    the user often carries out layout changes in the simulation model, e.g. moving,
    adding or deleting equipment. However, those changes cause time consuming, additional
    modeling of the motion paths for the user. Our motion planning algorithm reduces
    these changes by automatically determining the motion paths for moving objects,
    depending on an actual model layout without colliding with other objects. The
    algorithm works on the basis of the virtual scene\x92s 3D-data used for the simulation
    model\x92s visualization. We demonstrate the technique with a multi-floor building
    example."

  text: We present a parallel algorithm for the rendering of complex three-dimensional
    scenes. The algorithm runs across heterogeneous architectures of PC-clusters consisting
    of a visualization-node, equipped with a powerful graphics adapter, and cluster
    nodes requiring weaker graphics capabilities only. The visualization-node renders
    a mixture of scene objects and simplified meshes (Reliefboards). The cluster nodes
    assist the visualization-node by asynchronous computing of Reliefboards, which
    are used to replace and render distant parts of the scene. Our algorithm is capable
    of gaining significant speedups if the cluster's nodes provide weak graphics adapters
    only. We trade the number of cluster nodes off the scene objects' image quality.

  text: Many professional cluster systems consist of nodes with different hardware
    configurations. Such heterogeneous environments require different load-balancing
    techniques than homogenous environments. The c-load-collision-protocol is able
    to achieve good results for data-management purposes. Using this protocol, we
    propose a way for load-balancing in interactive rendering environments. For this
    work, we implemented a parallel rendering system and took different picking strategies
    into account to compare the results. The advantage of our approach compared to
    other approaches is that we group the available nodes of a cluster into two different
    categories, based on the hardware abilities. Some nodes are used solely for rendering,
    while others serve as secondary storage and to assist the former ones by performing
    auxiliary calculations.

  text: "Typischerweise sind die Knoten eines PC-Clusters nicht mit leistungsfähigen
    Grafikkarten ausgestattet. Dennoch bieten Cluster-Betreiber einige wenige Rechenknoten
    an, die mit Highend-Grafikkarten ausgestattet sind, um beispielsweise eine PowerWall
    zu betreiben. Wenn zwischen diesen unterschiedlichen Knotentypen ein schnelles
    Netzwerk existiert, kann die Bilderzeugung durch die Knoten mit schwacher Grafikkarte
    beschleunigt werden. Dabei können die unterschiedlichen Knotentypen unterschiedliche
    Aufgabe bearbeiten. In einem solchen heterogenen System, müssen die unterschiedlichen
    entstehenden Lasten auf andere Weise verteilt werden, als in einem System, bei
    dem alle Knoten gleich ausgestattet sind. Wir präsentieren in dieser Arbeit Lastbalancierungsmechanismen,
    die in einem parallelen Out-of-Core-Renderingsystem für heterogene PC-Cluster
    eingesetzt werden.\r\n"

  text: We present an approach for real-time rendering of complex 3D scenes consisting
    of millions of polygons on limited graphics hardware. In a preprocessing step,
    powerful hardware is used to gain fine granular global visibility information
    of a scene using an adaptive sampling algorithm. Additively the visual influence
    of each object on the eventual rendered image is estimated. This influence is
    used to select the most important objects to display in our approximative culling
    algorithm. After the visibility data is compressed to meet the storage capabilities
    of small devices, we achieve an interactive walkthrough of the Power Plant scene
    on a standard netbook with an integrated graphics chipset.

  text: Modern companies are nowadays confronted with an increasing demand of multiple
    products, where they need to perform more flexible every day. Cost-intensive decisions
    are to be confirmed in short times, in order to minimize risks and secure efficient
    production programs as well as material flows. Tools for this digital planning
    via simulation methods are one well established possibility to receive decision
    support. Nevertheless, the creation of the necessary simulation models is a complicated
    and error-prone process, where complexity of modeling, validation and verification
    depends on the used tool and its functionalities. This paper presents implemented
    concepts for an innovative user support in his tasks of verification and validation
    of simulation models during the execution of a simulation run. Time-intensive
    procedures like stopping simulation, parameterization and restarting within the
    problem analysis are simplified. So the user is able to focus on the real problem
    solving task.
