    • Generalized Trackball for Surfing Over Surfaces 

      Malomo, Luigi; Cignoni, Paolo; Scopigno, Roberto (The Eurographics Association, 2016)
      We present an efficient 3D interaction technique: generalizing the well known trackball approach, this technique unifies and blends the two common interaction mechanisms known as panning and orbiting. The approach allows ...

    • Interactive Analytical Treemaps for Visualisation of Call Centre Data 

      Roberts, Richard C.; Tong, Chao; Laramee, Robert S.; Smith, Gary A.; Brookes, Paul; D'Cruze, Tony (The Eurographics Association, 2016)
      In the United Kingdom alone, there are over one million employees working at over 5,000 call centres. Some estimates claim approximately four million call centre employees in Europe. In this unique application paper we ...

    • Kernel-Reflection Sequences 

      Szécsi, László; Bendefy, Zoltán; Kacsó, Ágota (The Eurographics Association, 2016)
      Complex geometries, like those of plants, rocks, terrain, or even clouds are challenging to model in a way that allows for real-time rendering but does not make concessions in terms of visible detail. In this paper we ...

    • Low Cost Handheld 3D Scanning for Architectural Elements Acquisition 

      Allegra, Dario; Gallo, Giovanni; Inzerillo, Laura; Lombardo, Marcella; Milotta, Filippo L. M.; Santagati, Cettina; Stanco, Filippo (The Eurographics Association, 2016)
      3D scanning has gone a long way since its first appearance in cultural heritage digitization and modeling. In the recent years some new low cost, fast, accurate emerging technologies are flooding the market. Envisioning ...

    • Manipulating Topological Decompositions of Non-Manifold Shapes 

      Canino, David (The Eurographics Association, 2016)
      Decomposing a non-manifold shape into its almost manifold components is a powerful tool for analyzing its complex structure. Many techniques for decomposing a non-manifold shape are available in the current literature, and ...

    • Persistent Homology: a Step-by-step Introduction for Newcomers 

      Fugacci, Ulderico; Scaramuccia, Sara; Iuricich, Federico; Floriani, Leila De (The Eurographics Association, 2016)
      Persistent homology is a powerful notion rooted in topological data analysis which allows for retrieving the essential topological features of an object. The attention on persistent homology is constantly growing in a large ...

    • Practical Free-form RTI Acquisition with Local Spot Lights 

      Pintus, Ruggero; Ciortan, Irina Mihaela; Giachetti, Andrea; Gobbetti, Enrico (The Eurographics Association, 2016)
      We present an automated light calibration pipeline for free-form acquisition of shape and reflectance of objects using common off-the-shelf illuminators, such as LED lights, that can be placed arbitrarily close to the ...

    • Practical Offline Rendering of Woven Cloth 

      Nelson, Vidar; McEvoy, Peter M.; Fratarcangeli, Marco (The Eurographics Association, 2016)
      The techniques for rendering woven cloth employed in a production environment often neglect many of the structural features of the fabric, as well as light-scattering processes that occur in the yarn. Research in this area ...

    • Retinal Image Analysis with Shearlets 

      Levet, Francesco; Duval-Poo, Miguel A.; Vito, Ernesto De; Odone, Francesca (The Eurographics Association, 2016)
      In this paper we propose a method for segmenting blood vessels in retinal images based on the shearlet transform. Shearlets are a relatively new directional multi-scale framework for signal analysis, which have been shown ...

    • Selective Rasterized Ray-traced Reflections on the GPU 

      Kastrati, Mattias Frid; Goswami, Prashant (The Eurographics Association, 2016)
      Ray-tracing achieves impressive effects such as realistic reflections on complex surfaces but is also more computationally expensive than classic rasterization. Rasterized ray-tracing methods can accelerate ray-tracing by ...

    • STAG 2016: Frontmatter 

      Gianni Pintore; Filippo Stanco (Eurographics Association, 2016)

    • Surface Reconstruction from Range Images 

      Mariosa, Gianfranco; Fioraio, Nicola; Franchi, Alessandro; Stefano, Luigi Di (The Eurographics Association, 2016)
      In this work we propose an algorithm for fast and detailed surface reconstruction from range images. Our method extends the well-known Ball Pivoting Algorithm (BPA) so to exploit the inherent structure of range images, ...

    • Tonal Art Maps with Image Space Strokes 

      Szécsi, László; Szirányi, Marcell; Kacsó, Ágota (The Eurographics Association, 2016)
      This paper presents a hybrid hatching solution that uses robust and fast texture space hatching to gather stroke fragments, but fits stylized brush strokes over those fragments in image space. Thus we obtain a real-time ...

    • Tracking the Evolution of Rainfall Precipitation Fields Using Persistent Maxima 

      Biasotti, Silvia; Cerri, Andrea; Pittaluga, Simone; Sobrero, Davide; Spagnuolo, Michela (The Eurographics Association, 2016)
      In this paper we propose a novel methodology for tracking the maxima of rainfall precipitation fields, whose changes in time may give interesting insights on the evolution of storm. Our approach is based on a topological ...

    • Vocal One Switch (VOS) Selection Interfaces for Virtual and Augmented Reality Hands-free Tasks 

      Manuri, Federico; Sanna, Andrea; Lamberti, Fabrizio; Paravati, Gianluca (The Eurographics Association, 2016)
      Several virtual and augmented reality tasks involve users in hands-free interactions; in this case, speech-based systems are often preferred for their intuitiveness and naturalness. On the other hand, the robustness of ...
