    • Evaluating Isosurfaces with Level-set-based Information Maps 

      Wei, Tzu-Hsuan; Lee, Teng-Yok; Shen, Han-Wei (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      While isosurfaces have been widely used for scalar data visualization, it is often difficult to determine if the selected isosurfaces for visualization are sufficient to represent the entire scalar field. In this paper, ...
    • Constructing Isosurfaces with Sharp Edges and Corners using Cube Merging 

      Bhattacharya, Arindam; Wenger, Rephael (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      A number of papers present algorithms to construct isosurfaces with sharp edges and corners from hermite data, i.e. the exact surface normals at the exact intersection of the surface and grid edges. We discuss some fundamental ...
    • Preface and Table of Contents 

      B. Preim, P. Rheingans, and H. Theisel (The Eurographics Association and Blackwell Publishing Ltd., 2013)
    • Sifted Disks 

      Ebeida, Mohamed S.; Mahmoud, Ahmed H.; Awad, Muhammad A.; Mohammed, Mohammed A.; Mitchell, Scott A.; Rand, Alexander; Owens, John D. (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We introduce the Sifted Disk technique for locally resampling a point cloud in order to reduce the number of points. Two neighboring points are removed and we attempt to find a single random point that is sufficient to ...
    • Analytic Rasterization of Curves with Polynomial Filters 

      Manson, Josiah; Schaefer, Scott (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a method of analytically rasterizing shapes that have curved boundaries and linear color gradients using piecewise polynomial prefilters. By transforming the convolution of filters with the image from an integral ...
    • Sharpening Out of Focus Images using High-Frequency Transfer 

      Tao, Michael W.; Malik, Jitendra; Ramamoorthi, Ravi (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Focus misses are common in image capture, such as when the camera or the subject moves rapidly in sports and macro photography. One option to sharpen focus-missed photographs is through single image deconvolution, but ...
    • View-Dependent Realtime Rendering of Procedural Facades with High Geometric Detail 

      Krecklau, Lars; Born, Janis; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present an algorithm for realtime rendering of large-scale city models with procedurally generated facades. By using highly detailed assets like windows, doors, and decoration such city models can provide an extremely ...
    • Rendering Gigaray Light Fields 

      Birklbauer, Clemens; Opelt, Simon; Bimber, Oliver (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a caching framework with a novel probability-based prefetching and eviction strategy applied to atomic cache units that enables interactive rendering of gigaray light fields. Further, we describe two new use ...
    • A Data-Driven Approach to Realistic Shape Morphing 

      Gao, Lin; Lai, Yu-Kun; Huang, Qi-Xing; Hu, Shi-Min (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Morphing between 3D objects is a fundamental technique in computer graphics. Traditional methods of shape morphing focus on establishing meaningful correspondences and finding smooth interpolation between shapes. Such ...
    • Sparse Modeling of Intrinsic Correspondences 

      Pokrass, Jonathan; Bronstein, Alexander M.; Bronstein, Michael M.; Sprechmann, Pablo; Sapiro, Guillermo (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a novel sparse modeling approach to non-rigid shape matching using only the ability to detect repeatable regions. As the input to our algorithm, we are given only two sets of regions in two shapes; no descriptors ...
    • Coupled Quasi-harmonic Bases 

      Kovnatsky, Artiom; Bronstein, Michael M.; Bronstein, Alexander M.; Glashoff, Klaus; Kimmel, Ron (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      The use of Laplacian eigenbases has been shown to be fruitful in many computer graphics applications. Today, state-of-the-art approaches to shape analysis, synthesis, and correspondence rely on these natural harmonic bases ...
    • Landmark-Guided Elastic Shape Analysis of Spherically-Parameterized Surfaces 

      Kurtek, Sebastian; Srivastava, Anuj; Klassen, Eric; Laga, Hamid (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We argue that full surface correspondence (registration) and optimal deformations (geodesics) are two related problems and propose a framework that solves them simultaneously. We build on the Riemannian shape analysis of ...
    • Primitive Trees for Precomputed Distance Queries 

      Lee, Sung-Ho; Park, Taejung; Kim, Chang-Hun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We propose the primitive tree, a novel and compact space-partition method that samples and reconstructs a distance field with high accuracy, even for regions far from the surfaces. The primitive tree is based on the octree ...
    • Analytic Visibility on the GPU 

      Auzinger, Thomas; Wimmer, Michael; Jeschke, Stefan (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This paper presents a parallel, implementation-friendly analytic visibility method for triangular meshes. Together with an analytic filter convolution, it allows for a fully analytic solution to anti-aliased 3D mesh rendering ...
    • Adaptive Quantization Visibility Caching 

      Popov, Stefan; Georgiev, Iliyan; Slusallek, Philipp; Dachsbacher, Carsten (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Ray tracing has become a viable alternative to rasterization for interactive applications and also forms the basis of most global illumination methods. However, even today's fastest ray-tracers offer only a tight budget ...
    • A Novel Projection Technique with Detail Capture and Shape Correction for Smoke Simulation 

      Wu, Xiaoyue; Yang, Xubo; Yang, Yang (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Smoke simulation on a large grid is quite time consuming and most of the computation time is spent on the projection step.We present a novel projection method which produces quite similar visual results as those produced ...
    • Geometry-Aware Volume-of-Fluid Method 

      Cho, Junghyun; Ko, Hyeong-Seok (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      We present a new framework to simulate moving interfaces in viscous incompressible two phase flows. The goal is to achieve both conservation of the fluid volume and a detailed reconstruction of the fluid surface. To these ...

      Ruiters, Roland; Schwartz, Christopher; Klein, Reinhard (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Bidirectional Texture Functions (BTF) have proven to be a well-suited representation for the reproduction of measured real-world surface appearance and provide a high degree of realism. We present an approach for designing ...
    • A Particle-Grid Method for Opaque Ice Formation 

      Im, Jaeho; Park, Hanwook; Kim, Jong-Hyun; Kim, Chang-Hun (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      This paper presents a particle-grid method to simulate the generation of opaque ice which has air bubbles in it. Water temperature is diffused over a grid, and the exchange of dissolved air between ice and water particles ...
    • By-example Synthesis of Curvilinear Structured Patterns 

      Zhou, Shizhe; Lasram, Anass; Lefebvre, Sylvain (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Many algorithms in Computer Graphics require to synthesize a pattern along a curve. This is for instance the case with line stylization, to decorate objects with elaborate patterns (chains, laces, scratches), or to synthesize ...
