    • 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 ...
    • Context-Aware Skeletal Shape Deformation 

      Weber, Ofir; Sorkine, Olga; Lipman, Yaron; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We describe a system for the animation of a skeleton-controlled articulated object that preserves the fine geometric details of the object skin and conforms to the characteristic shapes of the object specified through a ...
    • Contrast Restoration by Adaptive Countershading 

      Krawczyk, Grzegorz; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      The ABSTRACT is to be in fully-justified italicized text, between two horizontal lines, in one-column format, below the author and affiliation information. Use the word Abstract as the title, in 9-point Times, boldface ...
    • Crowds by Example 

      Lerner, Alon; Chrysanthou, Yiorgos; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...
    • 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 ...
    • Depth-of-Field Rendering by Pyramidal Image Processing 

      Kraus, M.; Strengert, M. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present an image-based algorithm for interactive rendering depth-of-field effects in images with depth maps. While previously published methods for interactive depth-of-field rendering suffer from various rendering ...
    • 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 ...
    • 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 ...
    • A Finite Element Method on Convex Polyhedra 

      Wicke, Martin; Botsch, Mario; Gross, Markus (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present a method for animating deformable objects using a novel finite element discretization on convex polyhedra. Our finite element approach draws upon recently introduced 3D mean value coordinates to define smooth ...
    • A Generic Pigment Model for Digital Painting 

      Xu, Songhua; Tan, Haisheng; Jiao, Xiantao; Lau, Francis C.M.; Pan, Yunhe (The Eurographics Association and Blackwell Publishing Ltd, 2007)
    • Geodesic-Controlled Developable Surfaces for Modeling Paper Bending 

      Bo, Pengbo; Wang, Wenping (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representation of a developable surface as the envelope ...
    • Global Illumination using Photon Ray Splatting 

      Herzog, Robert; Havran, Vlastimil; Kinuwaki, Shinichi; Myszkowski, Karol; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      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 ...
    • 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 ...
    • Highly Parallel Fast KD-tree Construction for Interactive Ray Tracing of Dynamic Scenes 

      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) ...
