    • A Quick and Automatic Image Based Modeling and Rendering System 

      Yerex, Keith; Birkbeck, Neil; Cobzas, Dana; Jagersand, Martin (Eurographics Association, 2004)
      We present a complete and automatic system for object capture from video, Internet delivery, and real-time photorealistic rendering. Shape from silhouette is used to capture an approximate enveloping geometry, the visual ...
    • Tone Mapping in VR Environments 

      Hausner, Alexander; Stamminger, Marc (Eurographics Association, 2004)
      Tone mapping is the process of mapping high dynamic range images to the low dynamic range of current displays. So far, tone mapping research was focused on static images, but with powerful graphics hardware available today, ...
    • Region Completion in a Single Image 

      Zhang, Yunjun; Xiao, Jiangjian; Shah, Mubarak (Eurographics Association, 2004)
      Natural images and Photographs sometimes may contain stains or undesired objects covering significant portions of the images. Region completion is a method to fill in such significant portions of an image by using the ...
    • Packing Square Tiles into One Texture 

      Decaudin, Philippe; Neyret, Fabrice (Eurographics Association, 2004)
      This paper deals with the packing of square tiles of the same size into one texture. Texture size is constrained by the graphics hardware. In particular, width and height resolutions must be powers of two. To cover the ...
    • Uniform Sampling for Image-based Rendering Shiny Objects 

      Gong, Minglun; Yang, Yee-Hong (Eurographics Association, 2004)
      A novel sampling technique is presented, which can evenly sample all rays that pass through a rectangular surface. Different view directions are uniformly sampled based on the shape of a spiral. Projection positions are ...
    • 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 ...
    • An Oriented Particle and Generalized Spring Model for Fast Prototyping Deformable Objects 

      Jeong, Il-Kwon; Lee, Inho (Eurographics Association, 2004)
      We present a new mass-spring system, in particular, by using an oriented particle and generalized spring model, which can be used for fast prototyping or animation of deformable objects. Conventional mass-spring system is ...
    • Modulating View-dependent Textures 

      Jagersand, Martin; Cobzas, Dana; Yerex, Keith (Eurographics Association, 2004)
      We present a texturing approach for image-based modeling and rendering, where instead of using one (or a blend of a few) sample images, new view dependent textures are synthesized by modulating a differential texture basis. ...
    • A Real Time Light Probe 

      Unger, Jonas; Gustavson, Stefan; Ollila, M.; Johannesson, M. (Eurographics Association, 2004)
      We present a novel system capable of capturing high dynamic range (HDR) Light Probes at video speed. Each Light Probe frame is built from an individual full set of exposures, all of which are captured within the frame time. ...
    • 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 ...
    • 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 Spectral Gamut-Mapping Environment with Rendering Parameter Feedback 

      Bell, Ian E.; Alexander, Simon K. (Eurographics Association, 2004)
      This paper proposes a prototypical environment for gamut mapping in spectral space. Images are rendered in terms of light and material parameters by a symbolic ray tracer, and the parameter ranges are adjusted, without ...
    • 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 ...
    • 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 ...
    • A Web-Based Multimedia Virtual Reality Environment for E-Learning 

      McArdle, Gavin; Monahan, Teresa; Bertolotto, Michela; Mangina, Eleni (Eurographics Association, 2004)
      The past decade has seen major advances in the availability of broadband computer access. With this everincreasing connection speed and improved Internet performance more and more web-based applications are becoming ...
    • Virtual Clay for Direct Hand Manipulation 

      Dewaele, Guillaume; Cani, Marie-Paule (Eurographics Association, 2004)
      In order to make virtual modeling as easy as real clay manipulation, we describe a realtime virtual clay model, specially designed for direct hand manipulation. We build on a previous layered model for clay, extending it ...
