      This tutorial covers a variety of methods for 3D shape matching and retrieval that are characterized by the use of a real-valued function defined on the shape (mapping function) to derive its signature. The methods are ...
    • An Accurate Implicit Field Representation for Meshes and Its Adapted Triangulation Algorithms 

      Fournier, Marc; Dischler, J. - M.; Bechmann, D. (The Eurographics Association, 2007)
      The classic implicit scalar field distance transform representation of a mesh is very useful to perform many mesh processing operations and to obtain better results than with other methods. In this paper we propose a new ...
    • Adaptive Abstraction of 3D scenes in Real-Time 

      Redmond, Niall; Dingliana, John (The Eurographics Association, 2007)
      We present an approach for creating abstracted renderings of 3D scenes in real-time. We create painterly renderings with edge detail using varying levels of abstraction dependent on regions of interest within a scene. Image ...

      A software tool to analyze 4D cardiac CT data sets for planning radiosurgical ablations in the heart is presented. Volume rendering and data processing are performed using a GPU. The user visualizes the data from inside ...
    • 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 ...
    • The Arnolfini Portrait in 3D - Creating Virtual World of a Painting with Inconsistent Perspective 

      Jansen, Philip H.; Ruttkay, Zsofia M. (The Eurographics Association, 2007)
      We report on creating a 3d virtual reconstruction of the scene shown in "The Arnolfini Portrait" by Jan van Eyck. This early Renaissance painting, if painted faithfully, should confirm to one-point perspective, however it ...
    • Automated Combination of Real-Time Shader Programs 

      Trapp, Matthias; Döller, Jürgen (The Eurographics Association, 2007)
      This work proposes an approach for automatic and generic runtime-combination of high-level shader programs. Many of recently introduced real-time rendering techniques rely on such programs. The fact that only a single ...
    • 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 ...
    • Capturing Reflectance - From Theory to Practice 

      Lensch, Hendrik P. A.; Goesele, Michael; M¨uller, Gero (The Eurographics Association, 2007)
      One important problem in photorealistic or predictive rendering nowadays is to realistically model the light interaction with objects. Measurements can capture the reflection properties of real world surface, i.e., they ...
