    • 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 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 ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...
