    • Serious Games: Broadening Games Impact Beyond Entertainment 

      Sawyer, Ben (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Computer and videogames for many years has been an island of technology and design innovation largely left to itself as it morphed from a cottage business into a global media and software industry. While there have been ...

    • Shape-aware Volume Illustration 

      Chen, Wei; Lu, Aidong; Ebert, David S. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We introduce a novel volume illustration technique for regularly sampled volume datasets. The fundamental difference between previous volume illustration algorithms and ours is that our results are shape-aware, as they ...

    • Skeleton-based Variational Mesh Deformations 

      Yoshizawa, Shin; Belyaev, Alexander; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, a new free-form shape deformation approach is proposed. We combine a skeleton-based mesh deformation technique with discrete differential coordinates in order to create natural-looking global shape deformations. ...

    • Soft Articulated Characters with Fast Contact Handling 

      Galoppo, Nico; Otaduy, Miguel A.; Tekin, Serhat; Gross, Markus; Lin, Ming C. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Fast contact handling of soft articulated characters is a computationally challenging problem, in part due to complex interplay between skeletal and surface deformation. We present a fast, novel algorithm based on a layered ...

    • Stackless KD-Tree Traversal for High Performance GPU Ray Tracing 

      Popov, Stefan; Guenther, Johannes; Seidel, Hans-Peter; Slusallek, Philipp (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Significant advances have been achieved for realtime ray tracing recently, but realtime performance for complex scenes still requires large computational resources not yet available from the CPUs in standard PCs. Incidentally, ...

    • Style Transfer Functions for Illustrative Volume Rendering 

      Bruckner, S.; Groeller, M. E. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Illustrative volume visualization frequently employs non-photorealistic rendering techniques to enhance important features or to suppress unwanted details. However, it is difficult to integrate multiple non-photorealistic ...

    • Superresolution Reflectance Fields: Synthesizing images for intermediate light directions 

      Fuchs, Martin; Lensch, Hendrik P. A.; Blanz, Volker; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Captured reflectance fields tend to provide a relatively coarse sampling of the incident light directions. As a result, sharp illumination features, such as highlights or shadow boundaries, are poorly reconstructed during ...

    • Synthetic Shutter Speed Imaging 

      Telleen, J.; Sullivan, A.; Yee, J.; Wang, O.; Gunawardane, P.; Collins, I.; Davis, J. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Hand held long exposures often result in blurred photographs due to camera shake. Long exposures are desirable both for artistic effect and in low-light situations. We propose a novel method for digitally reducing imaging ...

    • Textured Liquids based on the Marker Level Set 

      Mihalef, V.; Metaxas, D.; Sussman, M. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this work we propose a new Eulerian method for handling the dynamics of a liquid and its surface attributes (for example its color). Our approach is based on a new method for interface advection that we term the Marker ...

    • Texturing Internal Surfaces from a Few Cross Sections 

      Pietroni, Nico; Otaduy, Miguel A.; Bickel, Bernd; Ganovelli, Fabio; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We introduce a new appearance-modeling paradigm for synthesizing the internal structure of a 3D model from photographs of a few cross-sections of a real object. When the internal surfaces of the 3D model are revealed as ...

    • Variational 3D Shape Segmentation for Bounding Volume Computation 

      Lu, Lin; Choi, Yi-King; Wang, Wenping; Kim, Myung-Soo (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We propose a variational approach to computing an optimal segmentation of a 3D shape for computing a union of tight bounding volumes. Based on an affine invariant measure of e-tightness, the resemblance to ellipsoid, a ...

    • Visibility Sampling on GPU and Applications 

      Eisemann, Elmar; Decoret, Xavier (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we show how recent GPUs can be used to very efficiently and conveniently sample the visibility between two surfaces, given a set of occluding triangles. We use bitwise arithmetics to evaluate, encode, and ...

    • Volume Preservation of Multiresolution Meshes 

      Sauvage, Basile; Hahmann, Stefanie; Bonneau, Georges-Pierre (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Geometric constraints have proved to be efficient for enhancing the realism of shape animation. The present paper addresses the computation and the preservation of the volume enclosed by multiresolution meshes. A wavelet ...

    • What can Computer Graphics expect from 3D Computer Vision? 

      Sara, Radim (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Computer Vision is a discipline whose ultimate goal is to interpret optical images of real scenes. It is well understood that such a problem is cursed by ambiguity of interpretation and uncertainty of evidence. Despite ...
