      We present a framework to study electrical charge phenomena on human hair. We propose a fiber based hair model which bases on the special theory of Cosserat Rods to overcome the well known difficulties one has to deal with ...
    • Physically Based Simulation and Visualization of Fire in Real-Time using the GPU 

      Rødal, Samuel; Storli, Geir; Gundersen, Odd Erik (The Eurographics Association, 2006)
      In this paper we present a physically based framework for real-time simulation and visualization of fire using the GPU. The physics of fire is modeled through a combination of a fluid solver and a combustion process causing ...
    • Ubiquitous Virtual Reality: Accessing Shared Virtual Environments through Videoconferencing Technology 

      Pfeiffer, Thies; Weber, Matthias; Jung, Bernhard (The Eurographics Association, 2005)
      This paper presents an alternative to existing methods for remotely accessing Virtual Reality (VR) systems. Common solutions are based on specialised software and/or hardware capable of rendering 3D content, which not only ...
    • VRECKO: Virtual Reality Framework 

      Flasar, Jan; Pokluda, Ludek; O lej ek, Radek; Kolcárek, Pavel; Sochor, Jirí (The Eurographics Association, 2005)
      In this paper, we present a framework for experimenting with virtual environments. The architecture of the system VRECKO is designed for the rapid prototyping of techniques for human-computer interaction. The architecture ...
    • Freehand 3D Curve Recognition and Oversketching 

      Han, Li; Amicis, Raffaele De; Conti, Giuseppe (The Eurographics Association, 2005)
      In the CAD/CAS field, the increasing domination of spline-based graphic objects has driven a great attention to methods focusing on the management of free-form curves. Based on the quick brainstorm illustration and stepwise ...
    • Click and Brush: A Novel Way of Finding Correlations and Relationships in Visualizations 

      Wright, Michael A. E.; Roberts, Jonathan C. (The Eurographics Association, 2005)
      Brushing is a commonly used interaction technique that allows users to select items or an area of the visualization as the user moves the mouse. Brushing is often used with multiple views, where any co-related information ...
    • Real-time Simulation of Crowds Using Voronoi Diagrams 

      Champagne, J.; Tang, W. (The Eurographics Association, 2005)
      In this paper, we present a novel approach for real-time simulation of crowds. Our method is to compute generalised 2D Voronoi diagrams on environment maps for the locations of agents in the crowds. The Voronoi diagrams ...
