    • 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 ...
    • Metropolis Instant Radiosity 

      Segovia, B.; Iehl, J.C.; Peroche, B. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present Metropolis Instant Radiosity (MIR), an unbiased algorithm to solve the Light Transport problem. MIR is a hybrid technique which consists in representing the incoming radiance field by a set of Virtual Point ...
    • Bitmask Soft Shadows 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Recently, several real-time soft shadow algorithms have been introduced which all compute a single shadow map and use its texels to obtain a discrete scene representation. The resulting micropatches are backprojected onto ...
    • 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 ...
    • Precomputed Radiance Transfer Field for Rendering Interreflections in Dynamic Scenes 

      Pan, Minghao; Wang Xinguo Liu, Rui; Peng, Qunsheng; Bao, Hujun (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we introduce a new representation - radiance transfer fields (RTF) - for rendering interreflections in dynamic scenes under low frequency illumination. The RTF describes the radiance transferred by an ...
    • Efficient Reflectance and Visibility Approximations for Environment Map Rendering 

      Green, Paul; Kautz, Jan; Durand, Fredo (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present a technique for approximating isotropic BRDFs and precomputed self-occlusion that enables accurate and efficient prefiltered environment map rendering. Our approach uses a nonlinear approximation of the BRDF as ...
    • Online Motion Capture Marker Labeling for Multiple Interacting Articulated Targets 

      Yu, Qian; Li, Qing; Deng, Zhigang (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we propose an online motion capture marker labeling approach for multiple interacting articulated targets. Given hundreds of unlabeled motion capture markers from multiple articulated targets that are ...
    • Interactive Visual Workspaces with Dynamic Foveal Areas and Adaptive Composite Interfaces 

      Cotting, Daniel; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      This paper presents novel techniques and metaphors for on-demand visual workspaces in everyday office environments, providing space-efficient, flexible and highly interactive graphical user interfaces using projected ...
    • 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 ...
    • Consistent Viewing and Interaction for Multiple Users in Projection-Based VR Systems 

      De Haan, Gerwin; Molenaar, Rene; Koutek, Michal; Post, Frits H. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In projection-based Virtual Reality (VR) systems, typically only one headtracked user views stereo images rendered from the correct view position. For other users, who are presented a distorted image, moving with the first ...
    • A Bidirectional Light Field - Hologram Transform 

      Ziegler, Remo; Bucheli, Simon; Ahrenberg, Lukas; Magnor, Marcus; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, we propose a novel framework to represent visual information. Extending the notion of conventional image-based rendering, our framework makes joint use of both light fields and holograms as complementary ...
    • 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 ...
    • Diorama Construction From a Single Image 

      Assa, J.; Wolf, L. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Diorama artists produce a spectacular 3D effect in a confined space by generating depth illusions that are faithful to the ordering of the objects in a large real or imaginary scene. Indeed, cognitive scientists have ...
    • High-Quality Adaptive Soft Shadow Mapping 

      Guennebaud, Gael; Barthe, Loic; Paulin, Mathias (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      The recent soft shadow mapping technique [GBP06] allows the rendering in real-time of convincing soft shadows on complex and dynamic scenes using a single shadow map. While attractive, this method suffers from shadow ...
    • Omni-directional Relief Impostors 

      Andujar, C.; Boo, J.; Brunet, P.; Fairen, M.; Navazo, I.; Vazquez, P.; Vinacua, A. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Relief impostors have been proposed as a compact and high-quality representation for high-frequency detail in 3D models. In this paper we propose an algorithm to represent a complex object through the combination of a ...
    • 3D Video Billboard Clouds 

      Waschbuesch, Michael; Wuermlin, Stephan; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      3D video billboard clouds reconstruct and represent a dynamic three-dimensional scene using displacement-mapped billboards. They consist of geometric proxy planes augmented with detailed displacement maps and combine the ...
    • Real-time homogenous translucent material editing 

      Xu, Kun; Gao, Yue; Li, Yong; Ju, Tao; Hu, Shi-Min (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      This paper presents a novel method for real-time homogenous translucent material editing under fixed illumination. We consider the complete analytic BSSRDF model proposed by Jensen et al. [JMLH01], including both multiple ...
    • Defocus Magnification 

      Bae, Soonmin; Durand, Fredo (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      A blurry background due to shallow depth of field is often desired for photographs such as portraits, but, unfortunately, small point-and-shoot cameras do not permit enough defocus because of the small diameter of their ...
    • 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 ...
