    • Partial Shape Matching Using Transformation Parameter Similarity 

      Guerrero, Paul; Auzinger, Thomas; Wimmer, Michael; Jeschke, Stefan (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In this paper, we present a method for non‐rigid, partial shape matching in vector graphics. Given a user‐specified query region in a 2D shape, similar regions are found, even if they are non‐linearly distorted. Furthermore, ...

    • Probably Approximately Symmetric: Fast Rigid Symmetry Detection With Global Guarantees 

      Korman, Simon; Litman, Roee; Avidan, Shai; Bronstein, Alex (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a fast algorithm for global rigid symmetry detection with approximation guarantees. The algorithm is guaranteed to find the best approximate symmetry of a given shape, to within a user‐specified threshold, with ...

    • Purkinje Images: Conveying Different Content for Different Luminance Adaptations in a Single Image 

      Arpa, Sami; Ritschel, Tobias; Myszkowski, Karol; Çapın, Tolga; Seidel, Hans‐Peter (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Providing multiple meanings in a single piece of art has always been intriguing to both artists and observers. We present Purkinje images, which have different interpretations depending on the luminance adaptation of the ...

    • Real‐Time Isosurface Extraction With View‐Dependent Level of Detail and Applications 

      Scholz, Manuel; Bender, Jan; Dachsbacher, Carsten (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Volumetric scalar data sets are common in many scientific, engineering and medical applications where they originate from measurements or simulations. Furthermore, they can represent geometric scene content, e.g. as distance ...

    • Sample‐Based Manifold Filtering for Interactive Global Illumination and Depth of Field 

      Bauszat, P.; Eisemann, M.; John, S.; Magnor, M. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a fast reconstruction filtering method for images generated with Monte Carlo–based rendering techniques. Our approach specializes in reducing global illumination noise in the presence of depth‐of‐field effects ...

    • Seamless, Static Multi‐Texturing of 3D Meshes 

      Pagés, R.; Berjón, D.; Morán, F.; García, N. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      In the context of 3D reconstruction, we present a static multi‐texturing system yielding a seamless texture atlas calculated by combining the colour information from several photos from the same subject covering most of ...

    • Semi‐Regular Triangle Remeshing: A Comprehensive Study 

      Payan, F.; Roudet, C.; Sauvage, B. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Semi‐regular triangle remeshing algorithms convert irregular surface meshes into semi‐regular ones. Especially in the field of computer graphics, semi‐regularity is an interesting property because it makes meshes highly ...

    • Stable and Fast Fluid–Solid Coupling for Incompressible SPH 

      Shao, X.; Zhou, Z.; Magnenat‐Thalmann, N.; Wu, W. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      The solid boundary handling has been a research focus in physically based fluid animation. In this paper, we propose a novel stable and fast particle method to couple predictive–corrective incompressible and geometric ...

    • A Vectorial Framework for Ray Traced Diffusion Curves 

      Prévost, Romain; Jarosz, Wojciech; Sorkine‐Hornung, Olga (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Diffusion curves allow creating complex, smoothly shaded images by diffusing colours defined at curves. These methods typically require the solution of a global optimization problem (over either the pixel grid or an ...

    • A Visualization Tool Used to Develop New Photon Mapping Techniques 

      Spencer, B.; Jones, M. W.; Lim, I. S. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a visualization tool aimed specifically at the development and optimization of photon map denoising methods. Our tool allows the rapid testing of hypotheses and algorithms through the use of parallel coordinates, ...

    • Visualizing the Evolution of Communities in Dynamic Graphs 

      Vehlow, C.; Beck, F.; Auwärter, P.; Weiskopf, D. (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      The community structure of graphs is an important feature that gives insight into the high‐level organization of objects within the graph. In real‐world systems, the graph topology is oftentimes not static but changes over ...
