    • Applications of Information Theory to Computer Graphics 

      Sbert, Mateu; Feixas, Miquel; Rigau, Jaume; Viola, Ivan; Chover, Miguel (The Eurographics Association, 2007)
      We present different applications of information theory to computer graphics, based on the use of the measures of entropy, mutual information, f-divergences and generalized entropies. The application areas are hierarchical ...
    • Reeb Chart Unfolding Based 3D Shape Signatures 

      Tierny, Julien; Vandeborre, Jean-Philippe; Daoudi, Mohamed (The Eurographics Association, 2007)
      This paper presents a novel surface parameterization based technique that addresses the pose insensitive shape signature problem for surface models of arbitrary genus. It is based on the key idea that two surface models ...
    • Painterly Effects Rendering with Focus Based Level of Detail 

      Levente, Kovács; Tamás, Szirányi (The Eurographics Association, 2007)
      We present a novel method for automatically creating scalable and portable 2D non-photorealistically rendered (NPR) images with painterly effects, with level of detail control. The novelty of the approach lies both in using ...
    • Tangible Heritage: Production of Astrolabes on a Laser Engraver 

      Zotti, Georg (The Eurographics Association, 2007)
      The astrolabe, an analog computing device, used to be the iconic instrument of astronomers during the Middle Ages. It allowed a multitude of operations of practical astronomy which were otherwise cumbersome to perform in ...
    • The Visual Computing of Projector-Camera Systems 

      Bimber, Oliver; Iwai, Daisuke; Wetzstein, Gordon; Grundhöfer, Anselm (The Eurographics Association, 2007)
      This state-of-the-art report focuses on real-time image correction techniques that enable projector-camera systems to display images onto screens that are not optimized for projections, such as geometrically complex, colored ...
    • Spectral Methods for Mesh Processing and Analysis 

      Zhang, Hao; Kaick, Oliver van; Dyer, Ramsay (The Eurographics Association, 2007)
      Spectral methods for mesh processing and analysis rely on the eigenvalues, eigenvectors, or eigenspace projections derived from appropriately defined mesh operators to carry out desired tasks. Early works in this area can ...
    • Photorealistic Real-Time Visualization of Cultural Heritage: A Case Study of Friedrichsburg Castle in Germany 

      Kuchar, Robert; Schairer, Timo; Straßer, Wolfgang (The Eurographics Association, 2007)
      This paper presents a novel highly immersive and interactive VR (virtual reality) installation targeted on photorealistic real-time visualization. Although applicable to many other scenarios, this work is focused primarily ...
    • Bridging Semantic Web and Digital Shapes 

      Papaleo, Laura; Floriani, Leila De; Hendler, Jim (The Eurographics Association, 2007)
      Since the volume of multimedia content available on the Web is continuously increasing, a clear need for advanced techniques capable of performing an effective retrieval and management of such data. In this context, in ...
    • Fast GPU-based Visibility Computation for Natural Illumination of Volume Data Sets 

      Ritschel, Tobias (The Eurographics Association, 2007)
      Pre-computed radiance transfer (PRT) has been used to render volumetric data under distant low-frequency illumination at real-time rates, including natural illumination, soft shadows, attenuation from semi-transparent ...
    • Construction of Non-Blobby Surface from Particles 

      Harada, Takahiro; Koshizuka, Seiichi; Kawaguchi, Yoichiro (The Eurographics Association, 2007)
      This paper presents a method that can construct a surface with a thin region or sharp edges from particles. The surface is constructed in two stages. An implicit surface is generated by assigning a density distribution to ...

    • Extended Game Platform for Novice Programmers 

      Rankin, Yolanda; Lechner, Thomas (The Eurographics Association, 2007)
      In an attempt to recruit and retain computer science majors, game design courses have become increasingly popular in academia. Game design encompasses multiple stages of product development, takes an average of two or more ...
    • Stabilized Noise 

      Yoon, Jong-Chul; Lee, In-Kwon (The Eurographics Association, 2007)
      Perlin noise is generated by interpolation of a pre-defined random number table. However since the random number table is generated without considering the ideal properties of noise for computer graphics, the resulting ...
    • Visual Mining of Text Collections 

      Minghim, Rosane; Levkowitz, Haim (The Eurographics Association, 2007)
      What happens if you have to examine and reach conclusions from a considerable number of textual documents? If you are faced with this task or with developing tools for completing this task, this tutorial is for you. Examining ...
    • Computational Photography 

      Raskar, Ramesh; Tumblin, Jack; Mohan, Ankit; Agrawal, Amit; Li, Yuanzen (The Eurographics Association, 2007)
