    • Deep Opacity Maps 

      Yuksel, Cem; Keyser, John (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new method for rapidly computing shadows from semi-transparent objects like hair. Our deep opacity maps method extends the concept of opacity shadow maps by using a depth map to obtain a per pixel distribution ...

    • Designing Multi-projector VR Systems: from Bits to Bolts 

      Soares, Luciano Pereira; Dias, Miguel Salles; Jorge, Joaquim Armando Pires; Raposo, Alberto; Araújo, Bruno Rodrigues De; Bastos, Rafael (The Eurographics Association, 2008)
      Immersive multi-projection environments are becoming affordable for many research centers, but these solutions need several integration steps to be fully operational; some of these steps are difficult and not in a common ...

    • Detail-In-Context Visualization for Satellite Imagery 

      Boettger, Joachim; Preiser, Martin; Balzer, Michael; Deussen, Oliver (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We use the complex logarithm as a transformation for the visualization and navigation of highly complex satellite and aerial imagery. The resulting depictions show details and context with greatly different scales in one ...

    • Distortion-Free Steganography for Polygonal Meshes 

      Bogomjakov, Alexander; Gotsman, Craig; Isenburg, Martin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ...

    • Dynamic Sampling and Rendering of Algebraic Point Set Surfaces 

      Guennebaud, Gael; Germann, Marcel; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Algebraic Point Set Surfaces (APSS) define a smooth surface from a set of points using local moving least-squares (MLS) fitting of algebraic spheres. In this paper we first revisit the spherical fitting problem and provide ...

    • Effect of Character Animacy and Preparatory Motion on Perceptual Magnitude of Errors in Ballistic Motion 

      Reitsma, P. S. A.; Andrews, J.; Pollard, N. S. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      An increasing number of projects have examined the perceptual magnitude of visible artifacts in animated motion. These studies have been performed using a mix of character types, from detailed human models to abstract ...

    • Efficient and Dynamic Simplification of Line Drawings 

      Shesh, Amit; Chen, Baoquan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a pipeline for rendering dynamic 2D/3D line drawings efficiently. Our main goal is to create efficient static renditions and coherent animations of line drawings in a setting where lines can be ...

    • Efficient Soft Tissue Modelling Using Charged Particle Control Points 

      Buckley, Oliver; John, Nigel W. (The Eurographics Association, 2008)
      As the performance levels of personal computers increases so does the desire for more realistic and immersive software and simulation. An area where this is particularly the case is that of medical training simulation, ...

    • Efficient Spherical Harmonics Lighting with the Preetham Skylight Model 

      Habel, Ralf; Mustata, Bogdan; Wimmer, Michael (The Eurographics Association, 2008)
      We present a fast and compact representation of a skylight model for spherical harmonics lighting, especially for outdoor scenes. This representation allows dynamically changing the sun position and weather conditions on ...

    • Efficient Visualization of Architectural Models from a Structure and Motion Pipeline 

      Farenzena, Michela; Fusiello, Andrea; Gherardi, Riccardo (The Eurographics Association, 2008)
      State of the art three dimensional reconstruction pipelines can nowadays produce models up to several million polygons without any human intervention from a set of digital images or video. Such models are able to stretch ...

    • eNVyMyCar: a Multi-player Car Racing Game for Teaching Computer Graphics 

      Ganovelli, Fabio; Corsini, Massimiliano (The Eurographics Association, 2008)
      The development of a computer game is widely used as a means to convey Computer Sciences concepts. There are several reasons for that: it stimulates creativity, it provides an immediate sense of achievement when the code ...

    • Evaluation of a Mobile MR Geovisualisation Interface 

      Liarokapis, Fotis (The Eurographics Association, 2008)
      This paper presents experimental results of a mobile mixed reality interface designed for geovisualization of 3D realistic urban environments which allows dynamic switching between three visualization domains: a virtual ...

    • An Example-based Procedural System for Element Arrangement 

      Ijiri, Takashi; Mech, Radomir; Igarashi, Takeo; Miller, Gavin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling ...

    • Expressive Facial Gestures From Motion Capture Data 

      Ju, Eunjung; Lee, Jehee (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Human facial gestures often exhibit such natural stochastic variations as how often the eyes blink, how often the eyebrows and the nose twitch, and how the head moves while speaking. The stochastic movements of facial ...

    • Fast Force Field Approximation and its Application to Skeletonization of Discrete 3D Objects 

      Brunner, D.; Brunnett, G. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a novel method to approximate the force field of a discrete 3d object with a time complexity that is linear in the number of voxels. We define a rule, similar to the distance transform, to propagate ...
