      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 ...

      We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly ...
    • 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 ...

      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 ...
    • Markerless 4 gestures 6 DOF real-time visual tracking of the human hand with automatic initialization 

      Schlattmann, Markus; Kahlesz, Ferenc; Sarlette, Ralf; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper we present a novel computer vision based hand-tracking technique, which is capable of robustly tracking 6+4DOF of the human hand in real-time (at least 25 frames per second) with the help of 3 (or more) ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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, ...
    • 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 ...
    • Ray-Casted BlockMaps for Large Urban Models Visualization

    • Mesh Segmentation via Spectral Embedding and Contour Analysis 

      Liu, Rong; Zhang, Hao (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We propose a mesh segmentation algorithm via recursive bisection where at each step, a sub-mesh embedded in 3D is first spectrally projected into the plane and then a contour is extracted from the planar embedding. We rely ...
