    • Adaptive Surface Texture Synthesis Using Round-Shaped Neighbourhoods 

      Chen, D.; Dong, F. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel surface texture synthesis method, which is capable of producing high-quality results by performing the synthesis within an effective multi-resolution scheme using an adaptive texture similarity ...

    • Book Review 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • Camera Control in Computer Graphics 

      Christie, Marc; Olivier, Patrick; Normand, Jean-Marie (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Recent progress in modelling, animation and rendering means that rich, high fidelity virtual worlds are found in many interactive graphics applications. However, the viewer s experience of a 3D world is dependent on the ...

    • Compression and Importance Sampling of Near-Field Light Sources 

      Mas, Albert; Martin, Ignacio; Patow, Gustavo (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a method for compressing measured datasets of the near-field emission of physical light sources (represented by raysets). We create a mesh on the bounding surface of the light source that stores ...

    • Cultural Heritage As a Vehicle for Basic Research in Computing Science: Pasteur s Quadrant and a Use-Inspired Basic Research Agenda 

      Arnold, David (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Donald Stokes argued [Sto97] that for 50 years from the end of the Second World War to the end of the 20th century, there was an unhealthy taxonomy of research types which was formulated on a linear scale from pure to ...

    • Diffusion Based Photon Mapping 

      Schjoeth, L.; Sporring, J.; Fogh Olsen, O. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Density estimation employed in multi-pass global illumination algorithms give cause to a trade-off problem between bias and noise. The problem is seen most evident as blurring of strong illumination features. In particular, ...

    • Expressive Speech Animation Synthesis with Phoneme-Level Controls 

      Deng, Z.; Neumann, U. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel data-driven expressive speech animation synthesis system with phoneme-level controls. This system is based on a pre-recorded facial motion capture database, where an actress was directed to ...

    • Geometry Textures and Applications 

      De Toledo, Rodrigo; Wang, Bin; Levy, Bruno (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Geometry textures are a novel geometric representation for surfaces based on height maps. The visualization is done through a graphics processing unit (GPU) ray casting algorithm applied to the whole object. At rendering ...

    • GPU-Based Spherical Light Field Rendering with Per-Fragment Depth Correction 

      Todt, S.; Rezk-Salama, C.; Kolb, A.; Kuhnert, K.-D. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Image-based rendering techniques are a powerful alternative to traditional polygon-based computer graphics. This paper presents a novel light field rendering technique which performs per-pixel depth correction of rays for ...

    • High Performance GPU-based Proximity Queries using Distance Fields 

      Morvan, T.; Reimers, M.; Samset, E. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Proximity queries such as closest point computation and collision detection have many applications in computer graphics, including computer animation, physics-based modelling, augmented and virtual reality. We present ...

    • High-speed Marching Cubes using HistoPyramids 

      Dyken, Christopher; Ziegler, Gernot; Theobalt, Christian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an implementation approach for Marching Cubes (MC) on graphics hardware for OpenGL 2.0 or comparable graphics APIs. It currently outperforms all other known graphics processing units (GPU)-based iso-surface ...

    • Mapping Highly Detailed Colour Information on Extremely Dense 3D Models: The Case of David s Restoration 

      Dellepiane, M.; Callieri, M.; Ponchio, F.; Scopigno, R. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The support of advanced information technology (IT) to preservation, restoration and documentation of Cultural Heritage (CH) is becoming a very important goal for the research community. Michelangelo s David was one of the ...

    • Peek-in-the-Pic: Flying Through Architectural Scenes From a Single Image* 

      Shesh, Amit; Chen, Baoquan (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many casually taken tourist photographs comprise of architectural objects like houses, buildings, etc. Reconstructing such 3D scenes captured in a single photograph is a very challenging problem. We propose a novel ...

    • Real-Time Indirect Illumination and Soft Shadows in Dynamic Scenes Using Spherical Lights 

      Guerrero, P.; Jeschke, S.; Wimmer, M. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method for rendering approximate soft shadows and diffuse indirect illumination in dynamic scenes. The proposed method approximates the original scene geometry with a set of tightly fitting spheres. In previous ...
