      The increasing domination of spline-based graphic objects in CAD/CAS has driven a great attention to methods focusing on natural and intelligent free-form shape manipulation. We present a novel sketch-based system for the ...

    • An Efficient Algorithm for Adaptive Segmentation and Tessellation with Pixel Precision 

      Martinelli, Alessandro (The Eurographics Association, 2007)
      We propose a new algorithm to get a representation of a curved surface with the precision of the image pixel. This technique uses some results from Scan-line algorithms, but it considers also the new functionalities from ...

    • 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 ...

    • 3D Objects Face Clustering using Unsupervised Mean Shift 

      Farenzena, M.; Cristani, M.; Castellani, U.; Fusiello, A. (The Eurographics Association, 2007)
      In this paper, a novel approach to face clustering is proposed. The aim is the completely unsupervised extraction of planes in a polygonal a mesh, obtained from a 3D reconstruction process. In this context, 3D coordinates ...

    • 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 ...

    • Mobile Presence - a Computer Graphics Utopia? 

      Stork, Andre; Danch, Daniel (The Eurographics Association, 2007)
      In this paper we set out a future scenario of mobile presence. We will define our understanding of the term mobile presence. We will derive the requirements imposed by mobile presence with respect to computer graphics and ...

    • 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)
