    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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.
