  • An Occlusion Culling Toolkit for OpenSG PLUS 

    Staneker, Dirk (The Eurographics Association, 2003)
    Image-space occlusion culling is an useful approach to reduce the rendering load of large polygonal models in scienti c computing, mechanical engineering, or virtual medicine. Like most large model techniques, occlusion ...
  • Adaptive Tessellation of Subdivision Surfaces in OpenSG 

    Settgast, Volker; Müller, Kerstin; Fünfzig, Christoph; Fellner, Dieter W. (The Eurographics Association, 2003)
    The need for realistic models especially in virtual reality environments leads us to freeform shapes like subdivision surfaces. Based on a standard polygonal mesh, the modeller can build various kinds of shapes using an ...
  • OpenManip: An Extensible Cross-Scene-Graph Framework for Direct Object Manipulation 

    Braitmaier, Michael; Weiler, Manfred; Ertl, Thomas (The Eurographics Association, 2003)
    In this paper we describe a framework that exploits 3D widgets in order to allow for the direct manipulation of scene graph objects. The design of the frameworks is inspired by the OpenInventor manipulator functionality, ...
  • Advanced Environment Mapping in VR Applications 

    Kautz, Jan; Daubert, Katja; Seidel, Hans-Peter (The Eurographics Association, 2003)
    In this paper, we propose an approach for rendering diffuse and glossy reflections using environment maps. This approach is geared towards VR applications, where realism and fast rendering is important. We exploit certain ...
  • A Framework for Dynamic Connectivity Meshes 

    J.Vorsatz,; Seidel, Hans-Peter (The Eurographics Association, 2003)
    Implementing algorithms that are based on dynamic triangle meshes often requires updating internal datastructures as soon as the connectivity of the mesh changes. The design of a class hierarchy that is able to deal with ...
  • TRIPS - A Scalable Spatial Sound Library for OpenSG 

    Neumann, Tomas; Fünfzig, Christoph; Fellner, Dieter W. (The Eurographics Association, 2003)
    We present a Sound Library that is scalable on several computers and that brings the idea of a self-organized scenegraph to the Sound Library's interface. It supports the implementation of audio features right from the ...
  • Preserving Realism in Real-Time Rendering of Bidirectional Texture Functions 

    Meseth, Jan; Müller, Gero; Klein, Reinhard (The Eurographics Association, 2003)
    The Bidirectional Texture Function (BTF) is a suitable representation for the appearance of highly detailed surface structures under varying illumination and viewing conditions. Since real-time rendering of the full BTF ...
  • Parallel Stereo Visualization For ClustersWith OpenInventor: A Case Study For The Automotive Industry 

    Vega, Fernando; Suÿner, Gerd; Reuding, Thomas; Greiner, Günther (The Eurographics Association, 2003)
    Stereo visualization is an area which can greatly benefit from cluster computing due to the parallelizable nature of the rendering task. In order to implement this idea, we have developed a novel software architecture which ...
  • API Design for Adaptive Subdivision Surfaces 

    Sovakar, A.; Studnitz, A. von; Kobbelt, L. (The Eurographics Association, 2003)
    We present an API for adaptive subdivision schemes which is generic in the sense that it allows to define a composite subdivision operator as a sequence of atomic splitting and averaging rules. The API encapsulates a mesh ...
  • The OpenRT Application Programming Interface - Towards A Common API for Interactive Ray Tracing 

    Dietrich, Andreas; Wald, Ingo; Benthin, Carsten; Slusallek, Philipp (The Eurographics Association, 2003)
    For more than a decade now, interactive graphics has been shaped by triangle rasterization technology and the corresponding OpenGL graphics API. Since recently, however, interactive ray tracing is becoming a reality, and ...
  • Parallel Architecture of an Interactive Scientific Visualisation System for Large Datasets 

    Schneider, Sascha; May, Thorsten; Schmidt, Michael (The Eurographics Association, 2003)
    In this paper we describe a further development state of our system which is able to compute actual scientific and realistic visualization methods in parallel. This paper is related to the basic work we presented in one ...
