      Dellisanti, M.; Fiorentino, M.; Monno, G.; Uva, A. E. (The Eurographics Association, 2007)
      Multimodal interfaces are proved to increase the input\output bandwidth for a more efficient interaction in 3D activities. This work presents a novel framework designed to simplify the configuration procedures and to provide ...
    • VR Studio: Solid Modelling in a Virtual Reality Environment 

      Cappello, F.; Ingrassia, T.; Romano, M. (The Eurographics Association, 2007)
      Today one of the most important industrial needs is to improve the design process, making it faster and more robust; of course such a requirement can be obtained by using virtual reality. In the field of mechanical design, ...
    • Preserving Information from Real Objects to Digital Shapes 

      Albertoni, Riccardo; Papaleo, Laura; Robbiano, Francesco (The Eurographics Association, 2007)
      Nowadays, the success of the scientific enterprise largely depends on the ability of sharing resources among the scientific community. This problem is particularly relevant in the field of Computer Graphics and Vision. ...
    • 3D Scene Comparison using Topological Graphs 

      Paraboschi, L.; Biasotti, S.; Falcidieno, B. (The Eurographics Association, 2007)
      New technologies for shape acquisition and rendering of digital shapes have simplified the process of creating virtual scenes; nonetheless, shape annotation, recognition and manipulation of both the complete virtual scenes ...
    • Form Features in Non-manifold Shapes: A First Classification and Analysis 

      Crovetto, Chiara; Floriani, Leila De; Giannini, Franca (The Eurographics Association, 2007)
      During the industrial design process, a product model undergoes several analyses. One of the most common ones is the finite element analysis. This kind of analysis needs a simplified model, which can include idealised ...
    • Bringing the Semantics into Digital Shapes: the AIM@SHAPE Approach 

      Falcidieno, Bianca (The Eurographics Association, 2007)
      This presentation describes the main objectives and achievements of the European Network of Excellence AIM@SHAPE. This NoE is aimed to advance research in the direction of semantic-based shape representations and tools ...
    • Challenges for modern Scene-Graph Systems 

      Mueller-Wittig, Wolfgang; Voss, Gerrit (The Eurographics Association, 2007)
      Current scenegraph systems, especially systems used to build general purpose virtual reality systems, are trailing game engines and similar specialized systems in terms of the adaption of new renderingmethods like the ...
    • Marker-less Real-time Camera Registration for Mixed Reality 

      Liverani, Alfredo; Grandi, Stefania (The Eurographics Association, 2007)
      A real-time and robust algorithm for 3D camera registration in a Mixed Reality (MR) environment is described in this paper. The most used technique for camera pose (position and orientation with respect to a fixed or moving ...
    • Ramses: a Visual Steganographic System 

      Battiato, S.; Blasi, G. Di; Gallo, G.; Patti, S. (The Eurographics Association, 2007)
      Steganography is the art of "secret communication". Its goal is to transmit a message (information) hidden inside another visible message. The typical visible message used in many steganographic systems is a digital image ...
    • Rendering Order Optimization for SVGStat Improvement 

      Battiato, Sebastiano; Puglisi, Giovanni (The Eurographics Association, 2007)
      Vector representation of digital images offers a number of advantages over the more common raster representation, such as scalability and resolution independence. Many efforts have been made to deploy scalable raster ...
    • Realtime Wavelet Video Encoding with Generic Graphics Processing Unit 

      Stocklöw, Carsten; Noll, Stefan (The Eurographics Association, 2007)
      Wavelet video encoding with multi-resolution analysis is the base for a layered coding scheme. From one video source streams of different resolutions can be generated in one coding process. To reduce computing time the ...
    • Rewriting Rules for the Dual Graph of a Stripified CLOD Mesh 

      Porcu, Massimiliano B.; Scateni, Riccardo (The Eurographics Association, 2007)
      A triangular mesh is the piecewise linear approximation of a sampled or analytical surface, when each patch is a triangle. The connectivity of the mesh can be easily represented using its dual graph. Each node of such a ...
    • Explicit Adaptive Tessellation based on re-parametrization on Graphics Hardware 

      Martinelli, Alessandro (The Eurographics Association, 2007)
      We propose to use an explicit function for adaptive tessellation of parametric curves and surfaces. This function behaves as a new parametrization from the surface domain (or curve domain) to the domain itself; it is build ...
