    • A Procedural Approach to Solving Constraints of Articulated Bodies 

      Lee, J. Won; Baek, Nakhoon; Kim, Dongho; Hahn, James K. (Eurographics Association, 2000)
      Realistic motions of articulated bodies are usually generated by using physically-based animation methods such as constrained dynamics. However, these methods involve heavy computations and complicated numerical methods. ...
    • Visualizing Stars and Emission Nebulas 

      Nadeau, David R.; Genetti, Jon D.; Napear, Steve; Pailthorpe, Bernard; Emmart, Carter; Wesselak, Erik; Davidson, Dennis (Eurographics Association, 2000)
      We describe star and nebula visualization techniques used to create a 3D volumetric visualization of the Orion Nebula. The nebula’s ionization layer is modeled first as a surface model, derived from infrared and visible ...
    • Towards Communicating Agents and Avatars in Virtual Worlds 

      Nijholt, Anton; Hondorp, Hendri (Eurographics Association, 2000)
      We report about ongoing research in a virtual reality environment where visitors can interact with agents that help them to obtain information, to perform certain transactions and to collaborate with them in order to get ...
    • Spreading of the cultural heritage by means of multi-configurable, low cost virtual reality techniques 

      Flores, J.; Arias, J.; Saavedra, S.; Varela, E.; Ferro, J. M.; Taboada, J. (Eurographics Association, 2000)
      In the last few years, computer graphics techniques have been applied to preserve and promote the cultural heritage. In this first steps the bottleneck of these applications developed was the price of the hardware that ...
    • Combining finite element deformation with cutting for surgery simulations 

      Nienhuys, Han-Wen; van der Stappen, A. Frank (Eurographics Association, 2000)
      Interactive surgery simulations have conflicting requirements of speed and accuracy. In this paper we show how to combine a relatively accurate deformation model—the Finite Element (FE) method—and interactive cutting without ...
    • An Image Processing Approach to Detection of Ridges and Ravines on Polygonal Surfaces 

      Belyaev, Alexander; Ohtake, Yutaka (Eurographics Association, 2000)
      Surface creases, ridges and ravines, provide us with important information about the shapes of 3D objects and can be intuitively defined as curves on a surface along which the surface bends sharply. Exploring similarity ...
    • Selecting Effective Occluders for Visibility Culling 

      Koltun, Vladlen; Cohen-Or, Daniel (Eurographics Association, 2000)
      This paper deals with the problem of identifying effective occluders for visibility culling. The solid-angle metric is commonly used for measuring the potential significance of occluders from a single viewpoint. In this ...
    • Automatic Fitting of Digitised Contours at Multiple Scales through Curvature Scale Space 

      Mokhtarian, Farzin; Ung, Yoke Khim (Eurographics Association, 2000)
      The Curvature Scale Space (CSS) technique has been used in conjunction with Hermite curves for automatic fitting of digitised contours at multiple scales. CSS is a powerful contour shape descriptor which is expected to be ...
    • Interactive Vegetation Rendering with Slicing and Blending 

      Jakulin, Aleks (Eurographics Association, 2000)
      Detailed and interactive 3D rendering of vegetation is one of the challenges of traditional polygon-oriented computer graphics, due to large geometric complexity even of simple plants. In this paper we introduce a simplified ...
    • Discrete Analysis for Antialiased Lines 

      Boyer, V.; Bourdin, J. J. (Eurographics Association, 2000)
      This paper presents a new fast and smooth antialiasing technique. Drawing straight line is the graphic tool’s main primitive. Previous antialiasing techniques improve smoothness but slow down computation.
    • Scene understanding techniques using a virtual camera 

      Barral, Pierre; Dorme, Guillaume; Plemenos, Dimitri (Eurographics Association, 2000)
      An automatic computation of the path for a camera around a three-dimensional scene is discussed. Previous work on automatic virtual camera, based on a heuristic evaluation function, is reviewed, and new methods to improve ...
    • Component Based Human Animation Architecture 

      Jing, Huang; Fi, Chin Kah; Prakash, Edmond C. (Eurographics Association, 2000)
      This paper describes a method to predict the free reach movement of different components of the human body. Since the human body is composed of the following components: arms, legs, torso, head & neck, and each of these ...
    • Efficient Evaluation of the Field Functions of Soft Objects Using Interval Tree 

      Min, Kyung-Ha; Lee, In-Kwon; Park, Chan-Mo (Eurographics Association, 2000)
      We present an algorithm to evaluate the field function of a soft object efficiently. Instead of using a global field function that is defined by the sum of all local field functions, we consider only the set of local field ...
    • A Novel Image-Based Rendering System With A Longitudinally Aligned Camera Array 

      Li, Jiang; Zhou, Kun; Wang, Yong; Shum, Heung-Yeung (Eurographics Association, 2000)
    • Robust Polygons Clipping to Model Complex Objects 

      Segura, Rafael J.; Feito, Francisco R. (Eurographics Association, 2000)
      One of the most important problems to solve in Solids Modelling is computing the boolean operations for solids (union, intersection and difference). In order to implement these three operations an algorithm to compute the ...
    • Adding a scalar value to 2D vector field visualization: the BLIC (Bumped LIC) 

      Sanna, A.; Montrucchio, B. (Eurographics Association, 2000)
      Visualization of vector data produced from application areas such as computational fluid dynamics (CFD), environmental sciences, and material engineering is a challenging task. Texture-based methods reveal to be effective, ...
    • Collaboration in VEs − fact or fiction? 

      Hubbold, Roger J. (Eurographics Association, 2000)
      The growth of the Internet, and company intranets, fuelled by the promise of sophisticated on−line services, has raised expectations of rich collaborative virtual environments, in which humans can indulge in cooperative ...
    • Virtual Humans: Ten Problems Still Not Completely Solved 

      Thalmann, Daniel (Eurographics Association, 2000)
      During the 1980s, the academic establishment paid only scant attention to research on the animation of virtual humans. Today, however, almost every graphics journal, popular magazine, or newspaper devotes some space to ...
    • Principles of Computer Graphics: the experience of a class A user 

      Cailliau, Robert (Eurographics Association, 2000)
      Computer graphics has gone a long way from the early days in the 50’s and 60’s. Today we have the web, and it’s all visual that is the fashion. What does an unsuspecting user of computers, who is not a specialist, actually ...
