    • 2008 Eurographics Symposium on Parallel Graphics and Visualization 

      Weiskopf, Daniel (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • 29th EUROGRAPHICS General Assembly 

      Unknown author (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • Abstractive Representation and Exploration of Hierarchically Clustered Diffusion Tensor Fiber Tracts 

      Chen, Wei; Zhang, Song; Correia, Stephen; Ebert, David S. (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Diffusion tensor imaging (DTI) has been used to generate fibrous structures in both brain white matter and muscles. Fiber clustering groups the DTI fibers into spatially and anatomically related tracts. As an increasing ...

    • Accelerating Ray Tracing using Constrained Tetrahedralizations 

      Lagae, Ares; Dutre, Philip (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we introduce the constrained tetrahedralization as a new acceleration structure for ray tracing. A constrained tetrahedralization of a scene is a tetrahedralization that respects the faces of the scene geometry. ...

    • Accurate Shadows by Depth Complexity Sampling 

      Forest, Vincent; Barthe, Loic; Paulin, Mathias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The accurate generation of soft shadows is a particularly computationally intensive task. In order to reduce rendering time, most real-time and offline applications decorrelate the generation of shadows from the computation ...

    • An Adaptive Contact Model for the Robust Simulation of Knots 

      Spillmann, Jonas; Teschner, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper, we present an adaptive model for dynamically deforming hyper-elastic rods. In contrast to existing approaches, adaptively introduced control points are not governed by geometric subdivision rules. Instead, ...

    • Adaptive Surface Texture Synthesis Using Round-Shaped Neighbourhoods 

      Chen, D.; Dong, F. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a novel surface texture synthesis method, which is capable of producing high-quality results by performing the synthesis within an effective multi-resolution scheme using an adaptive texture similarity ...

    • Agile Spectrum Imaging: Programmable Wavelength Modulation for Cameras and Projectors 

      Mohan, Ankit; Raskar, Ramesh; Tumblin, Jack (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We advocate the use of quickly-adjustable, computer-controlled color spectra in photography, lighting and displays. We present an optical relay system that allows mechanical or electronic color spectrum control and use it ...

    • An Analysis of the In-Out BRDF Factorization for View-Dependent Relighting 

      Mahajan, Dhruv; Tseng, Yu-Ting; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Interactive rendering with dynamic natural lighting and changing view is a long-standing goal in computer graphics. Recently, precomputation-based methods for all-frequency relighting have made substantial progress in this ...

    • Animating Causal Overlays 

      Bartram, Lyn; Yao, Miao (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Most approaches to representing causality, such as the common causal graph, require a separate and static view, but in many cases it is useful to add the dimension of causality to the context of an existing visualization. ...

    • Apparent Greyscale: A Simple and Fast Conversion to Perceptually Accurate Images and Video 

      Smith, Kaleigh; Landes, Pierre-Edouard; Thollot, Joelle; Myszkowski, Karol (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a quick and simple method for converting complex images and video to perceptually accurate greyscale versions. We use a two-step approach first to globally assign grey values and determine colour ordering, ...

    • Articulated Object Reconstruction and Markerless Motion Capture from Depth Video 

      Pekelny, Yuri; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an algorithm for acquiring the 3D surface geometry and motion of a dynamic piecewise-rigid object using a single depth video camera. The algorithm identifies and tracks the rigid components in each frame, while ...

    • Augmented Panoramic Video 

      Hermans, C.; Vanaken, C.; Mertens, T.; Van Reeth, F.; Bekaert, P. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many video sequences consist of a locally dynamic background containing moving foreground subjects. In this paper we propose a novel way of re-displaying these sequences, by giving the user control over a virtual camera ...

    • Automatic Conversion of Mesh Animations into Skeleton-based Animations 

      De Aguiar, Edilson; Theobalt, Christian; Thrun, Sebastian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Recently, it has become increasingly popular to represent animations not by means of a classical skeleton-based model, but in the form of deforming mesh sequences. The reason for this new trend is that novel mesh deformation ...

    • Automatic Detection and Visualization of Distinctive Structures in 3D Unsteady Multi-fields 

      Jänicke, Heike; Böttinger, Michael; Tricoche, Xavier; Scheuermann, Gerik (The Eurographics Association and Blackwell Publishing Ltd., 2008)
      Current unsteady multi-field simulation data-sets consist of millions of data-points. To efficiently reduce this enormous amount of information, local statistical complexity was recently introduced as a method that identifies ...

    • Automatic Facsimile of Chinese Calligraphic Writings 

      Xu, Songhua; Jiang, Hao; Jin, Tao; Lau, Francis C.M.; Pan, Yunhe (The Eurographics Association and Blackwell Publishing Ltd, 2008)

    • Automatic Registration for Articulated Shapes 

      Chang, Will; Zwicker, Matthias (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present an unsupervised algorithm for aligning a pair of shapes in the presence of significant articulated motion and missing data, while assuming no knowledge of a template, user-placed markers, segmentation, or the ...

    • The Beam Radiance Estimate for Volumetric Photon Mapping 

      Jarosz, Wojciech; Zwicker, Matthias; Jensen, Henrik Wann (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new method for efficiently simulating the scattering of light within participating media. Using a theoretical reformulation of volumetric photon mapping, we develop a novel photon gathering technique for ...

    • A Biorthogonal Wavelet Approach based on Dual Subdivision 

      Zhang, Hui; Qin, Guiming; Qin, Kaihuai; Sun, Hanqiu (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper a biorthogonal wavelet approach based on Doo-Sabin subdivision is presented. In the dual subdivision like Doo-Sabin scheme, all the old control vertices disappear after one subdivision step, which is a big ...
