  • Information-Theoretic Oracle Based on Kernel Smoothness for Hierarchical Radiosity 

    Feixas, Miquel; Rigau, Jaume; Bekaert, Philippe; Sbert, Mateu (Eurographics Association, 2002)
    One of the main problems in the radiosity method is how to discretise the surfaces of a scene into mesh elements that allow us to accurately represent illumination. In this paper we present a robust information-theoretic ...
  • Hardware-Assisted Relief Texture Mapping 

    Fujita, Masahiro; Kanai, Takashi (Eurographics Association, 2002)
    Image-Based Rendering by Warping (IBRW) creates three-dimensional scene by deforming several 2D images with depth information. Image-based rendering has an advantage compared to traditional polygon rendering that the ...
  • An Image-Based Radiosity Representation 

    Mertens, Tom; Van Reeth, Frank (Eurographics Association, 2002)
    We present a geometry-independent radiosity representation which stems from image-based methodologies. Our image-based representation is inspired by the concept of layered depth images. To construct the radiosity function ...
  • Visibility Preprocessing Using Spherical Sampling of Polygonal Patches 

    Meruvia Pastor, Oscar E. (Eurographics Association, 2002)
    A technique is presented that permits fast view-reconstruction of individual objects. This method improves a previous approach to solve the problem of approximated view reconstruction by combining clustering of polygons ...
  • Dependent Tests Driven Filtering in Monte-Carlo Global Illumination 

    Csonka, Ferenc; Szirmay-Kalos, Laszlo; Kelemen, Csaba; Antal, György (Eurographics Association, 2002)
    This paper presents a multi-phase algorithm to solve the global illumination problem. In the first phase dependent tests are applied, i.e. the random walks of different pixels are built from the same random numbers. The ...
  • The Voronoi-Quadtree: construction and visualization 

    Coll, Narcís; Boada, Imma; Sellares, J.A. (Eurographics Association, 2002)
    We define a quadtree-based planar Voronoi diagram codification, the Voronoi-Quadtree, valid for generalized sites (points, line-segments, curve-arc segments, ...) and for different distance functions (Euclidean metrics, ...
  • On the Integration of Synthetic Objects with Real-World Scenes 

    Abad, Francisco; Camahort, Emilio; Vivó, Roberto (Eurographics Association, 2002)
    This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ...
  • Using pre-integrated Transfer Functions in an Interactive Software System for Volume 

    Knittel, Guenter (Eurographics Association, 2002)
    We explore possibilities to implement classification based on pre-integrated transfer functions in a software system for high-speed volume rendering. The major obstacle to remove is the large size of the multi-dimensional ...
  • Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics 

    Miyazaki, Ryo; Dobashi, Yoshinori; Nishita, Tomoyuki (Eurographics Association, 2002)
    Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating ...
  • Concise Tour to the Virtual Old Prague 

    Zara, Jiri (Eurographics Association, 2002)
    This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ...
  • Dynamics-Based Motion Synthesis by Simple Learning Control 

    Kiriazov, Petko (Eurographics Association, 2002)
    Point-to-point motion of a humanoid agent (or any mobile creature) is considered as a composition of basic movements related to the degrees of freedom. With time/energy performance criteria, such movements can be synthesized ...
  • Dynamic Motion Models 

    Grünvogel, Stefan Michael; Lange, Thorsten; Piesk, Jens (Eurographics Association, 2002)
    Real-time animation of virtual characters is a demanding task. We propose dynamic motion models which can create the motion of a virtual character in different styles and have the ability to change the animation while it ...
  • A Method for Creating Mosaic Images Using Voronoi Diagrams 

    Dobashi, Yoshinori; Haga, Toshiyuki; Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)
    This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications ...
  • Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field 

    De Floriani, Leila; Mesmoudi, Mohammed Mostefa; Danovaro, Emanuele (Eurographics Association, 2002)
    In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ...
  • Distance fields applied to character animation 

    Rudomin, Isaac; Castillo, J. (Eurographics Association, 2002)
    A general hybrid geometric-physical method that is useful for animating characters with skin, clothing and a MPEG-4 compatible face is presented. This method uses an approximation to the underlying musculo-skeletal structure ...
  • A Convolution-Based Algorithm for Animated Water Waves 

    Loviscach, Jörn (Eurographics Association, 2002)
    A non-linear partial differential equation solver is too sophisticated for computer graphics applications if they are only used to render effects like circular waves and ship wakes. We present an approach which simulates ...
  • Improved Integration for Cloth Simulation 

    Parks, David L.; Forsyth, David A. (Eurographics Association, 2002)
    Most methods of cloth simulation produce animations that do not move very freely; the result often looks like the material is “swimming”. The primary sources of this phenomenon are the non-physical dissipation terms often ...
  • Geometric Simplification of Foliage 

    Remolar, Inmaculada; Chover, Miguel; Belmonte, Oscar; Ribelles, Jose; Rebollo, Cristina (Eurographics Association, 2002)
    One of the most important challenges in real-time rendering of outdoor scenes is the representation of vegetation. This is due to the vast amount of polygons that are used to model vegetable species. The present automatic ...
  • Mesh Decimation for Displacement Mapping 

    Collins, Gordon; Hilton, Adrian (Eurographics Association, 2002)
    We present a mesh decimation algorithm for triangular meshes. Unlike other decimation algorithms we are not concerned with geometric error but with the existence of a displacement mapping which can map between the original ...
