      Doil, F.; Schreiber, W.; Alt, T.; Patron, C. (The Eurographics Association, 2003)
      The shortening of development cycles demand for efficient methods and tools for the planning of complex production systems. Recently immersive Virtual Reality technologies have been introduced to the manufacturing planning ...

    • Automated Testing of Virtual Reality Application Interfaces 

      Bierbaum, Allen; Hartling, Patrick; Cruz-Neira, Carolina (The Eurographics Association, 2003)
      We describe a technique for supporting testing of the interaction aspect of virtual reality (VR) applications. Testing is a fundamental development practice that forms the basis of many software engineering methodologies. ...

    • The blue-c Distributed Scene Graph 

      Naef, Martin; Lamboray, Edouard; Staadt, Oliver; Gross, Markus (The Eurographics Association, 2003)
      In this paper we present a distributed scene graph architecture for use in the blue-c, a novel collaborative immersive virtual environment. We extend the widely used OpenGL Performer toolkit to provide a distributed scene ...

    • Blue-c: A Spatially Immersive Display and 3D Video Portal 

      Gross, M. (The Eurographics Association, 2003)
      We present the blue-c, a new generation immersive projection and 3D video acquisition environment for telepresence and collaboration. It combines simultaneous acquisition of multiple life video streams with advanced 3D ...

    • CAD/CAE visualization in virtual environment for automotive industry 

      Paillot, D.; Merienne, F.; Thivent, S. (The Eurographics Association, 2003)
      In this paper we propose a method to link CAD models to an immersive environment. Since CAD models can not be directly viewed in a real-time visualization environment, we present here a complete chain of adapta-tion steps ...

    • Color Consistency for Digital Multi-Projector Stereo Display Systems : The HEyeWall and The Digital CAVE 

      Kresse, W.; Reiners, D.; Knöpfle, C. (The Eurographics Association, 2003)
      Digital projectors have a significant advantage over CRTs for IPT setups: brightness. But they also have a number of disadvantages, one of which is color consistency. This problem is exacerbated when using the Infitec ...

    • Color Gamut Matching for Tiled DisplayWalls 

      Wallace, Grant; Chen, Han; Li, Kai (The Eurographics Association, 2003)
      This paper presents a non-parametric full-gamut color matching algorithm. Color matching is important for the seamless appearance of tiled displays. In particular we address the case where the tiled display is composed of ...

    • Comparative Visualization of FEM-Based Cutting Simulations in a Virtual Environment 

      Klocke, Fritz; Straube, Andreas M. (The Eurographics Association, 2003)
      As one of the final steps in the industrial manufacturing chain, machining operations require significant economic consideration. At this stage, design components have already passed through several steps of this value-added ...
