  • An Accurate Illumination Model for Objects Coated with Multilayer Films 

    Hirayama, H.; Kaneda, K.; Yamashita, H.; Monden, Y. (Eurographics Association, 2000)
    This paper proposes an accurate illumination model for rendering objects coated with multilayer films. Optical phenomenaof multilayer films are caused by reflection, refraction, interference, and absorption of light inside ...
  • ALOHA : Adaptive Level Of Detail for Human Animation Towards a new framework 

    Giang, Thanh; Mooney, Robert; Peters, Christopher; Sullivan, Carol O. (Eurographics Association, 2000)
    The task of animating and rendering virtual humans in real-time is challenging. One must first establish a sense of realism through appearance, and then maintain this realism through correct and plausible motion, while ...
  • A Facial Repertoire for Animation 

    ten Hagen, Paul J. W. (Eurographics Association, 2000)
    Character design and facial animation of characters is among the most tedious parts of creation of animations. In contrast to body animations, performer data have not been successfully used for faces. The CharToon system ...
  • Visibility Complexity of a Region in Flatland 

    Rigau, Jaume; Feixas, Miquel; Sbert, Mateu (Eurographics Association, 2000)
    The aim of this paper is to study the visibility complexity of different regions in a 2D scene. Based on mutual information, which we used in our previous work to define scene complexity, we propose two measures that ...
  • Volumetric Textures 

    Gonzalez Clua, Esteban W.; Dreux, Marcelo (Eurographics Association, 2000)
    There are some types of nature elements that are adequately represented in Computer Graphics only through volumes. In order to visualize scenes with volumes, together with geometrical objects, it is necessary to make use ...
  • MeshSweeper: From Closest Point to Hausdorff Distance Between Meshes 

    Gueziec, A. (Eurographics Association, 2000)
    We introduce a new algorithm for computing the distance from a point to an arbitrary polygonal mesh. Our algorithm uses a multi-resolution hierarchy of bounding volumes generated by geometric simplification. Our algorithm ...
  • Imaging Geometry for Concentric Mosaics 

    Watson, G. C.; Vaughan, N.; Wright, M. W. (Eurographics Association, 2000)
    Image-based models of environments can be captured with the use of a rotating video camera. In this paper we consider the nature of the display to develop a simple quantitative measure of the quality of ray sampling which ...
  • 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 ...
  • 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 ...
  • Interactive Modelling of Convolution Surfaces with an Extendable User Interface 

    Goto, Yuichiro; Pasko, Alexander (Eurographics Association, 2000)
    Convolution surfaces enable the user to model complex free-form shapes. Due to analytical solutions for some kernel functions and skeletal elements, it is possible to model convolution surfaces interactively. An extendable ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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.
