    • Acquisition, Synthesis and Rendering of Bidirectional Texture Functions 

      Müller, Gero; Meseth, Jan; Sattler, Mirko; Sarlette, Ralf; Klein, Reinhard (Eurographics Association, 2004)
      One of the main challenges in computer graphics is still the realistic rendering of complex materials such as fabric or skin. The difficulty arises from the complex meso structure and reflectance behavior defining the ...

    • Adaptive Brush Stroke Generation for Painterly Rendering 

      Park ChungAng, Youngsup; Yoon, Kyunghyun (Eurographics Association, 2004)
      We propose adaptive brush stroke generation for source images, using reference data. Colors used are formed by actual palette colors from artists. To create the palette, we have referred mostly to colors used in Van Gogh’s ...

      Thalmann, D.; Magnenat-Thalmann, N.; Donikian, S. (Eurographics Association, 2004)
      The necessity to model virtual population appears in many applications of computer animation and simulation. Such applications encompass several different domains - representative or autonomous agents in virtual environments, ...

    • Classification of Illumination Methods for Mixed Reality 

      Jacobs, Katrien; Loscos, Céline (Eurographics Association, 2004)
      A mixed reality (MR) represents an environment composed both by real and virtual objects. MR applications are more and more used, for instance in surgery, architecture, cultural heritage, entertainment, etc. For some of ...

    • Collision Detection for Deformable Objects 

      Teschner, M.; Kimmerle, S.; Heidelberger, B.; Zachmann, G.; Raghupathi, L.; Fuhrmann, A.; Cani, M.-P.; Faure, F.; Magnenat-Thalmann, N.; Strasser, W.; Volino, P. (Eurographics Association, 2004)
      Interactive environments for dynamically deforming objects play an important role in surgery simulation and entertainment technology. These environments require fast deformable models and very efficient collision handling ...

    • A Color Decomposition Method for Preserving Ukiyo-e Woodblocks 

      Terai, Tomokazu; Mizuno, Shinji; Okada, Minoru (Eurographics Association, 2004)
      In this paper we propose a color decomposition method for multicolor printing of watercolors including areas overlapping each print layer. Watercolors have an important feature that the observed colors are different on the ...

    • Enriching Animation Databases 

      Ahmed, Amr; Mokhtarian, Farzin; Hilton, Adrian (Eurographics Association, 2004)
      The paper presents a framework for enriching an existing basic animation databse by modifying existing motions to generate a variety of new motions. Intuitively controlled motion varities are generated on demand which ...

    • Frontier Sets: A Partitioning Scheme to Enable Scalable Virtual Environments 

      Steed, Anthony; Angus, Cameron (Eurographics Association, 2004)
      We present a new spatial partitioning scheme called frontier sets. Frontier sets build on the notion of a potentially visible set (PVS) [ARB90, TS91]. In a PVS a world is sub-divided into cells and for each cell all the ...

    • A Generic Method for Geometric Contraints Detection 

      Salvati, Marc; Lecallennec, Benoît; Boulic, Ronan (Eurographics Association, 2004)
      In this paper, we present a generic method to automatically detect geometric constraints on motion capture animations. At each frame, elementary geometric constraints are computed with respect to a reference which can ...

    • Geometric Algebra and its Application to Computer Graphics 

      Hildenbrand, Dietmar; Perwass, Christian; Dorst, Leo; Fontijne, Daniel (Eurographics Association, 2004)
      In this tutorial we will give an overview of Geometric Algebra and its application to computer graphics. First of all, we want to motivate the topic and give insights into some applications.

    • Interactive Modeling of Mushrooms 

      Desbenoit, Brett; Vanderhaghe, David; Galin, Eric; Grosjean, Jerôme (Eurographics Association, 2004)
      This paper presents a fast and efficient method for modeling mushrooms. Starting from a real world image, the designer defines a silhouette and specifies deformation parameters. Our system then automatically generates a ...

    • Interactive Physically-based Animation System for Dense Meshes 

      Kondo, Ryo; Kanai, Takashi (Eurographics Association, 2004)
      In this paper we describe an interactive physically-based animation system for dense meshes. Our method extracts a coarse mesh from an original mesh to make a tetrahedral mesh for the reduction of computational costs. For ...

    • Modeling clouds shape 

      Bouthors, Antoine; Neyret, Fabrice (Eurographics Association, 2004)
      We propose a model for representing the shape of cumulus clouds.We draw on several approaches that we combine and extend: We store a hierarchy of quasi-spherical particles (or blobs) living on top of each other. The shape ...

    • Modern Approaches to Augmented Reality 

      Bimber, Oliver; Raskar, Ramesh (Eurographics Association, 2004)
