    • Gearbox Widget for Fine Adjustments by Hand Motion 

      OSAWA, Noritaka; REN, Xiangshi (The Eurographics Association, 2003)
      manipulation by hand is not suitable for making fine adjustments to virtual objects in an immersive environment because it is difficult to hold an unsupported hand in midair and then to release an object at a fixed point. ...

      Oliveira, M.; Crowcroft, J.; Slater, M. (The Eurographics Association, 2003)
      A Virtual Environment (VE) presents a complex problem with interesting non-trivial challenges for software development. The majority of existing systems supporting VE are based on monolithic architectures, making maintenance ...
    • 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 ...
    • Haptic Rendering of Complex Force Fields 

      Krenek, Ales (The Eurographics Association, 2003)
      With a particular focus in scientific applications, we propose a method of haptic rendering of virtual environments which require rather complex calculations to evaluate their behaviour. Therefore it is not possible to ...
    • A Panoramic Walkthrough System with Occlusion Culling 

      Yang, Lining; Crawfis, Roger (The Eurographics Association, 2003)
      The interactive and high quality rendering of very complex scenes in a virtual environment is very difficult if not impossible to achieve. This research extends our previous EGVE paper that presents a panoramic walkthrough ...

      Based on the premise of a synergy between the interactive storytelling and VR training simulation this paper treats the main issues involved in practical realization of an immersive VR decision training system supporting ...
    • 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 ...
    • The Virtual Showcase as a new Platform for Augmented Reality Digital Storytelling ve 

      Bimber, Oliver; Encarnação, L. Miguel; Schmalstieg, Dieter (The Eurographics Association, 2003)
      In this paper we discuss a case study for which we applied a customized augmented reality display - the Virtual Showcase - as a new platform for digital storytelling. Different storytelling components are identified and ...
    • Double Exponential Smoothing: An Alternative to Kalman Filter-Based Predictive Tracking 

      Jr., Joseph J. LaViola (The Eurographics Association, 2003)
      We present novel algorithms for predictive tracking of user position and orientation based on double exponential smoothing. These algorithms, when compared against Kalman and extended Kalman filter-based predictors with ...
    • The ToolFinger: Supporting Complex Direct Manipulation in Virtual Environments 

      Wesche, Gerold (The Eurographics Association, 2003)
      Virtual environments (VEs) such as the Responsive Workbench were designed to support interactive, complex applications. The possibility of direct manual interaction with virtual objects, using both hands in a natural, ...
    • Fast Approximate Visible Set Determination for Point Sample Clouds 

      Mantler, Stephan; Fuhrmann, Anton L. (The Eurographics Association, 2003)
      We present a fast, efficient method to determine approximate visible sets for vegetation rendered as point sample clouds. A hardware accelerated preprocessing step is used to determine exact visibility for a selected set ...
    • Interacting with real time simulations - virtual reality in industry applications 

      Jönsson, A.; Bathelt, J.; Broman, G. (The Eurographics Association, 2003)
      Modern manufacturing machines are highly multidisciplinary, and with demands on short time-to-market, product development based on traditional prototype testing has become impractical. By using virtual models, it is possible ...
