  • Continuous Local Parameterization of Polygons 

    Maillot, Jerome (Eurographics Association, 2003)
    Texture mapping has now become a standard technique for adding visual details to 3d models. Nevertheless, intuitive mapping tools have made little progress in the past decade, compared to other computer graphics areas: ...
  • Automatic High Level Avatar Guidance Based on Affordance of Movement 

    Michael, Despina; Chrysanthou, Yiorgos (Eurographics Association, 2003)
    As virtual cities become ever more common and more extensive, the need to populate them with virtual pedestrians grows. One of the problems to be resolved for the virtual population is the behaviour simulation. Currently ...
  • A Framework for Video-based and Hardware-Accelerated Remote 3D-Visualization

  • Beyond Image Quality Comparison 

    Bornik, Alexander; Cech, Peter; Ferko, Andrej; Perko, Roland (Eurographics Association, 2003)
    We solve the problem of quantitative measuring of image quality, beyond the widely used MSE (mean square error) or even visual comparison. We combine eight feature-based and perceptually-oriented image quality metrics. The ...
  • Adaptive quantization with error bounds for compressed view-dependent multiresolution meshes 

    Grabner, Markus; Zach, Christopher (Eurographics Association, 2003)
    We present a simple method to adaptively determine compression parameters according to the given input data. Our method allows to make better use of the available dynamic range (number of bits per component of vertex ...
  • Animatope: A Manga-Styled Animation Expression Toolkit 

    Tohda, Asuka; Hasegawa, Sho; Inakage, Masa (Eurographics Association, 2003)
    Manga, a Japanese comic style, is becoming widely accepted within comic readers worldwide. In Manga, mimetic symbols and onomatopoeia symbols are heavily used to express emotions and various movements in a comic frame. In ...
  • Interactive Dynamic Environments Using Image-Based Modeling and Rendering 

    Davis, Timothy A.; Ficklin, Stephen P. (Eurographics Association, 2003)
    This paper presents a method for rendering a dynamic virtual environment using IBMR at interactive rates. Most IBMR methods are designed for use with static scenes and are awkward when extended temporally due to excessive ...
  • Parameter-driven freeform deformations 

    Song, Y.; Vergeest, J.S.M.; Saakes, D.P. (Eurographics Association, 2003)
    High-level parameters offer user an easy and intuitive tool to modify an existing model. In this paper, an approach of deforming freeform shapes using intrinsic parameters is proposed, where those parameters were not part ...
  • Shadow Mapping Based on Dual Depth Layers 

    Weiskopf, Daniel; Ertl, Thomas (Eurographics Association, 2003)
    Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual ...
  • Improved Indirect Photon Mapping withWeighted Importance Sampling 

    Szirmay-Kalos, Laszlo; Szecsi, Laszl (Eurographics Association, 2003)
    This paper offers a novel approach to the indirect photon mapping method. The placement of photons acting as virtual light sources is regarded as a cheap sampling scheme, allowing for the reuse of a complete shooting path ...
  • Multilevel modelling and rendering of architectural scenes 

    Kushal, Akash M.; Chanda, Gaurav; Shrivastava, Kanishka; Gupta, Mohit; Sanyal, Subhajit; Sriram, T. V. N.; Kalra, Prem; Banerjee, Subhashis (Eurographics Association, 2003)
    We present a novel approach for multilevel modelling and rendering of architectural scenes using a small set of photographs. Our approach is based on interactive probing of intuitive measures like lengths, widths and heights ...
  • A Precise Approach Calibrated by Experimental Data to Make an Artificial Impulse 

    Iguchi, Toshiko; Kodama, Tetsuya; Noborio, Hiroshi (Eurographics Association, 2003)
    Baraffs and Mirtichs approaches are well known so as to generate force and impulsive force artificially at collision between rigid bodies. However, both cannot be unfortunately applied for a practical use such as complex ...
  • Estimating Positions and Radiances of a Small Number of Light Sources for Real-Time Image-Based Lighting 

    Madsen, Claus B.; Sorensen, Mads K. D.; Vittrup, Michael (Eurographics Association, 2003)
    Image-based lighting (IBL) of virtual objects has become a popular approach to blending virtual and real scenes. In IBL an omni-directional image of a scene is used as the illumination environment for rendering virtual ...
  • Generation of Radiosity Texture Atlas for Realistic Real-Time Rendering 

    Ray, Nicolas; Ulysse, Jean-Christophe; Cavin, Xavier; Levy, Bruno (Eurographics Association, 2003)
    Radiosity methods are a both physically correct and efficient way to compute the global illumination giving the visual atmosphere to a 3D scene. In this paper, we present a new approach to optimizing the visualization of ...
  • Implicit Surface Reconstruction and uniform Sampling by Striped Marching Triangles 

    Leborán, Víctor; Pardo, Xose M. (Eurographics Association, 2003)
    The synthesis of computer models from real objects is a usual procedure in medical image processing and reverse engineering. In both cases, the main issues are to reach a topologically consistent and geometrically precise ...
