    • Head-eye Animation Corresponding to a Conversation for CG Characters 

      Masuko, Soh; Hoshino, Junichi (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      CG character animations, in which CG characters engage in conversations, are widely used in multimedia contents such as videos and games. In constructing such an animation, we should consider about many factors, such as ...

    • 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 ...

      Shevtsov, Maxim; Soupikov, Alexei; Kapustin, Alexander (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present a highly parallel, linearly scalable technique of kd-tree construction for ray tracing of dynamic geometry. We use conventional kd-tree compatible with the high performing algorithms such as MLRTA or frustum ...

    • Image Dequantization: Restoration of Quantized Colors 

      Kim, Tae-hoon; Ahn, Jongwoo; Choi, Min Gyu (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Color quantization replaces the color of each pixel with the closest representative color, and thus it makes the resulting image partitioned into uniformly-colored regions. As a consequence, continuous, detailed variations ...

    • Interactive Simulation of the Human Eye Depth of Field and Its Correction by Spectacle Lenses 

      Kakimoto, Masanori; Tatsukawa, Tomoaki; Mukai, Yukiteru; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      This paper describes a fast rendering algorithm for verification of spectacle lens design. Our method simulates refraction corrections of astigmatism as well as myopia or presbyopia. Refraction and defocus are the main ...

    • 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 ...

    • Layered Performance Animation with Correlation Maps 

      Neff, Michael; Albrecht, Irene; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Performance has a spontaneity and aliveness that can be difficult to capture in more methodical animation processes such as keyframing. Access to performance animation has traditionally been limited to either low degree ...

    • 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) ...

    • 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 ...

    • 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 ...

    • 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 ...

    • On-the-fly Curve-skeleton Computation for 3D Shapes 

      Sharf, Andrei; Lewiner, Thomas; Shamir, Ariel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      The curve-skeleton of a 3D object is an abstract geometrical and topological representation of its 3D shape. It maps the spatial relation of geometrically meaningful parts to a graph structure. Each arc of this graph ...

    • 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 ...

    • Pedestrian Reactive Navigation for Crowd Simulation: a Predictive Approach 

      Paris, Sebastien; Pettre, Julien; Donikian, Stephane (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      This paper addresses the problem of virtual pedestrian autonomous navigation for crowd simulation. It describes a method for solving interactions between pedestrians and avoiding inter-collisions. Our approach is agent-based ...

    • Precomputed Radiance Transfer Field for Rendering Interreflections in Dynamic Scenes
