    • Hardware-Accelerated, High-Quality Rendering Based on Trivariate Splines Approximating Volume Data 

      Kalbe, Thomas; Zeilfelder, Frank (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We develop an approach for hardware-accelerated, high-quality rendering of volume data using trivariate splines. The proposed quasi-interpolating schemes are realtime reconstructions. The low total degrees provide several ...

    • Real-Time Rendering and Editing of Vector-based Terrains 

      Bruneton, Eric; Neyret, Fabrice (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any ...

    • Sketching and Composing Widgets for 3D Manipulation 

      Schmidt, Ryan; Singh, Karan; Balakrishnan, Ravin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an interface for 3D object manipulation in which standard transformation tools are replaced with transient 3D widgets invoked by sketching context-dependent strokes. The widgets are automatically aligned to axes ...

    • Augmented Panoramic Video 

      Hermans, C.; Vanaken, C.; Mertens, T.; Van Reeth, F.; Bekaert, P. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re-displaying these sequences, by giving the user control over a virtual camera ...

    • Stereo Light Probe 

      Corsini, Massimiliano; Callieri, Marco; Cignoni, Paolo (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we present a practical, simple and robust method to acquire the spatially-varying illumination of a real-world scene. The basic idea of the proposed method is to acquire the radiance distribution of the scene ...

    • Video Relighting Using Infrared Illumination 

      Wang, Oliver; Davis, James; Chuang, Erika; Rickard, Ian; De Mesa, Krystle; Dave, Chirag (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Inappropriate lighting is often responsible for poor quality video. In most offices and homes, lighting is not designed for video conferencing. This can result in unevenly lit faces, distracting shadows, and unnatural ...

    • 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 ...

    • Spectral Geometry Processing with Manifold Harmonics 

      Vallet, B.; Levy, B. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an explicit method to compute a generalization of the Fourier Transform on a mesh. It is well known that the eigenfunctions of the Laplace Beltrami operator (Manifold Harmonics) define a function basis allowing ...

    • Curvature-Domain Shape Processing 

      Eigensatz, Michael; Sumner, Robert W.; Pauly, Mark (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We propose a framework for 3D geometry processing that provides direct access to surface curvature to facilitate advanced shape editing, filtering, and synthesis algorithms. The central idea is to map a given surface to ...

    • GPU Accelerated Direct Volume Rendering on an Interactive Light Field Display 

      Agus, Marco; Gobbetti, Enrico; Guitian, Jose Antonio Iglesias; Marton, Fabio; Pintore, Giovanni (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a GPU accelerated volume ray casting system interactively driving a multi-user light field display. The display, driven by a single programmable GPU, is based on a specially arranged array of projectors and a ...

    • CHC++: Coherent Hierarchical Culling Revisited 

      Mattausch, Oliver; Bittner, Jiri; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new algorithm for efficient occlusion culling using hardware occlusion queries. The algorithm significantly improves on previous techniques by making better use of temporal and spatial coherence of visibility. ...

    • Lighting and Occlusion in a Wave-Based Framework 

      Ziegler, Remo; Croci, Simone; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present novel methods to enhance Computer Generated Holography (CGH) by introducing a complex-valued wave-based occlusion handling method. This offers a very intuitive and efficient interface to introduce optical elements ...

    • 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 ...

    • Apparent Greyscale: A Simple and Fast Conversion to Perceptually Accurate Images and Video 

      Smith, Kaleigh; Landes, Pierre-Edouard; Thollot, Joelle; Myszkowski, Karol (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a quick and simple method for converting complex images and video to perceptually accurate greyscale versions. We use a two-step approach first to globally assign grey values and determine colour ordering, ...

    • Render2MPEG: A Perception-based Framework Towards Integrating Rendering and Video Compression 

      Herzog, Robert; Kinuwaki, Shinichi; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Currently 3D animation rendering and video compression are completely independent processes even if rendered frames are streamed on-the-fly within a client-server platform. In such scenario, which may involve time-varying ...

    • High-Resolution Volumetric Computation of Offset Surfaces with Feature Preservation 

      Pavic, Darko; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new algorithm for the efficient and reliable generation of offset surfaces for polygonal meshes. The algorithm is robust with respect to degenerate configurations and computes (self-)intersection free offsets ...

    • Surface Reconstruction From Non-parallel Curve Networks 

      Liu, L.; Bajaj, C.; Deasy, J. O.; Low, D. A.; Ju, T. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Building surfaces from cross-section curves has wide applications including bio-medical modeling. Previous work in this area has mostly focused on connecting simple closed curves on parallel cross-sections. Here we consider ...

    • Reduced Depth and Visual Hulls of Complex 3D Scenes 

      Bogomjakov, Alexander; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Depth and visual hulls are useful for quick reconstruction and rendering of a 3D object based on a number of reference views. However, for many scenes, especially multi-object, these hulls may contain significant artifacts ...
