    • Anisotropic Point Set Surfaces 

      Adamson, A.; Alexa, M. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Point Set Surfaces define smooth surfaces from regular samples based on weighted averaging of the points. Because weighting is done based on a spatial scale parameter, point set surfaces apply basically only to regular ...
    • Translational Covering of Closed Planar Cubic B-Spline Curves 

      Neacsu, Cristina; Daniels, Karen (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Spline curves are useful in a variety of geometric modeling and graphics applications and covering problems abound in practical settings. This work defines a class of covering decision problems for shapes bounded by spline ...
    • Soft Shadow Maps: Efficient Sampling of Light Source Visibility 

      Atty, Lionel; Holzschuch, Nicolas; Lapierre, Marc; Hasenfratz, Jean-Marc; Hansen, Charles; Sillion, Francois X. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Shadows, particularly soft shadows, play an important role in the visual perception of a scene by providing visual cues about the shape and position of objects. Several recent algorithms produce soft shadows at interactive ...
    • AFRIGRAPH: Computer Graphics in Africa 

      Gain, J. E.; Strasser, W. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • Occlusion-Driven Scene Sorting for Efficient Culling 

      Staneker, Dirk; Bartz, Dirk; Wolfgang, Strasser (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Image space occlusion culling is a powerful approach to reduce the rendering load of large polygonal models. However, occlusion culling is not for free; it trades overhead costs with the rendering costs of the possibly ...
    • Guest Editorial: Selected Papers from the 18th Brazilian Symposium on Computer Graphics and Image Processing (SIBGRAPI 2005) 

      Andreia, Maria; Rodrigues, Formico (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • GEncode: Geometry-driven compression for General Meshes 

      Lewiner, Thomas; Craizer, Marcos; Lopes, Helio; Pesco, Sinesio; Velho, Luiz; Medeiros, Esdras (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Performances of actual mesh compression algorithms vary significantly depending on the type of model it encodes. These methods rely on prior assumptions on the mesh to be efficient, such as regular connectivity, simple ...
    • A Randomized Approach for Patch-based Texture Synthesis using Wavelets 

      Tonietto, L.; Walter, M.; Jung, C. R. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      We present a wavelet-based approach for selecting patches in patch-based texture synthesis. We randomly select the first block that satisfies a minimum error criterion, computed from the wavelet coefficients (using 1D or ...
    • Editorial 

      Duke, David; Scopigno, Roberto (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • Errata 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • Verification of Physically Based Rendering Algorithms 

      Ulbricht, Christiane; Wilkie, Alexander; Purgathofer, Werner (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Within computer graphics, the field of predictive rendering is concerned with those methods of image synthesis that yield results that do not only look real, but are also radiometrically correct renditions of nature, i.e. ...
    • SVG.Open 2005 Conference 

      Neumann, Andreas (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • Third Eurographics Symposium on Geometry Processing (in cooperation with ACM SIGGRAPH) 

      Desbrun, Mathieu (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • Interactive Multiresolution Editing and Display of Large Terrains 

      Atlan, Samuel; Garland, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      In recent years, many systems have been developed for the real-time display of very large terrains. While many of these techniques combine high-quality rendering with impressive performance, most make the fundamental ...
    • Undersampled Light Field Rendering by a Plane Sweep 

      Liu, Yang; Chen, George; Max, Nelson; Hofsetz, Christian; McGuinness, Peter (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Images synthesized by light field rendering exhibit aliasing artifacts when the light field is undersampled; adding new light field samples improves the image quality and reduces aliasing but new samples are expensive to ...
    • Transformation and Normal Vector Calculation of Parametrically Defined Surfaces Based on Dual Vectors and Screw Theory: Application to Phong s Shading Model 

      Papageorgiou, Stavros G.; Aspragathos, Nikos A. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      This paper presents a new approach for the transformation and normal vector calculation algorithms of parametrically defined surfaces via dual vectors and line transformations. The surface is defined via dual points, the ...

      Mahovsky, J.; Wyvill, B. (The Eurographics Association and Blackwell Publishing Ltd, 2006)
    • A Comparative Evaluation of Metrics for Fast Mesh Simplification 

      Matias van Kaick, Oliver; Pedrini, Helio (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      Triangle mesh simplification is of great interest in a variety of knowledge domains, since it allows manipulation and visualization of large models, and it is the starting point for the design of many multiresolution ...
