    • 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 ...

    • 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 ...

    • 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 ...

    • Steerable Texture Synthesis 

      Taponecco, Francesca; Alexa, Marc (Eurographics Association, 2004)
      Texture synthesis is typically concerned with the creation of an arbitrarily sized texture from a small sample, where the pattern of the generated texture should be perceived as resembling the example. Most of the current ...

    • 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 ...

    • 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 ...

    • The Visualisation and Expression of Virtual 3DSurfaces Explored through Custom Developed Interactive Software, Optically Mixed Coloured Surface Contouring and Fine Art Printmaking 

      Lee, Peter John (Eurographics Association, 2004)
      This short presentation paper describes an exploration and the visualisation of virtual 3D compositions through custom developed software and fine art printmaking. The author, a trained and practising visual artist considers ...

    • 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 ...

    • Realtime Isosurface Extraction with Graphics Hardware 

      Reck, Frank; Dachsbacher, Carsten; Grosso, Roberto; Greiner, Günther; Stamminger, Marc (Eurographics Association, 2004)
      In this paper we introduce a method for the display of isosurfaces extracted from unstructured tetrahedral grids. Our algorithm completely runs on the graphics hardware. The tetrahedra are streamed into a vertex program, ...

    • Visual Model of Fire 

      Pszczolkowska, Dorota (Eurographics Association, 2004)
      This paper presents a fire model based on dynamic particle chains. The chains are shaped and moved by a varying velocity field and constitute a density field, which is rendered using the ray tracing method. What we want ...

    • SP-Octrees Visualization Using Impostors 

      Melero Rus, Francisco J.; Cano Olivares, Pedro; Torres Cantero, Juan Carlos (Eurographics Association, 2004)
      SP-Octrees (Space-Partition Octrees) allow a multiresolution representation of polyhedral objects, and have been successfully used in progressive transmission. Nonetheless, the SP-Octree is a solid modeling structure, ...

    • 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 ...

    • 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 ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
