      We present a method to find repeating topological structures in scalar data sets. More precisely, we compare all subtrees of two merge trees against each other - in an efficient manner exploiting redundancy. This provides ...
    • Mandatory Critical Points of 2D Uncertain Scalar Fields 

      Günther, David; Salmon, Joseph; Tierny, Julien (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density ...
    • Extracting Features from Time-Dependent Vector Fields Using Internal Reference Frames 

      Bhatia, Harsh; Pascucci, Valerio; Kirby, Robert M.; Bremer, Peer-Timo (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Extracting features from complex, time-dependent flow fields remains a significant challenge despite substantial research efforts, especially because most flow features of interest are defined with respect to a given ...
    • Opacity Optimization for Surfaces 

      Günther, Tobias; Schulze, Maik; Esturo, Janick Martinez; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ...
    • Sets of Globally Optimal Stream Surfaces for Flow Visualization 

      Schulze, Maik; Esturo, Janick Martinez; Günther, Tobias; Rössl, Christian; Seidel, Hans-Peter; Weinkauf, Tino; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ...
    • Preface and Table of Contents 

      H. Carr, P. Rheingans, and H. Schumann (The Eurographics Association and Blackwell Publishing Ltd., 2014)
    • Hierarchical Opacity Optimization for Sets of 3D Line Fields 

      Günther, Tobias; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ...
    • Pathline Glyphs 

      Hlawatsch, Marcel; Sadlo, Filip; Jang, Hajun; Weiskopf, Daniel (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Visualization of pathlines is common and highly relevant for the analysis of unsteady flow. However, pathlines can intersect, leading to visual clutter and perceptual issues. This makes it intrinsically difficult to provide ...
    • Multi-style Paper Pop-up Designs from 3D Models 

      Jr., Conrado R. Ruiz; Le, Sang N.; Yu, Jinze; Low, Kok-Lim (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Paper pop-ups are interesting three-dimensional books that fascinate people of all ages. The design and construction of these pop-up books however are done manually and require a lot of time and effort. This has led to ...
    • Dual-Color Mixing for Fused Deposition Modeling Printers 

      Reiner, Tim; Carr, Nathan; Mech, Radomir; Stava, Ondrej; Dachsbacher, Carsten; Miller, Gavin (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is ...
    • ExploreMaps: Efficient Construction and Ubiquitous Exploration of Panoramic View Graphs of Complex 3D Environments 

      Benedetto, Marco Di; Ganovelli, Fabio; Rodriguez, Marcos Balsa; Villanueva, Alberto Jaspe; Scopigno, Roberto; Gobbetti, Enrico (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We introduce a novel efficient technique for automatically transforming a generic renderable 3D scene into a simple graph representation named ExploreMaps, where nodes are nicely placed point of views, called probes, and ...
    • Clean Color: Improving Multi-filament 3D Prints 

      Hergel, Jean; Lefebvre, Sylvain (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Fused Filament Fabrication is an additive manufacturing process by which a 3D object is created from plastic filament. The filament is pushed through a hot nozzle where it melts. The nozzle deposits plastic layer after ...
    • Flower Reconstruction from a Single Photo 

      Yan, Feilong; Gong, Minglun; Cohen-Or, Daniel; Deussen, Oliver; Chen, Baoquan (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a semi-automatic method for reconstructing flower models from a single photograph. Such reconstruction is challenging since the 3D structure of a flower can appear ambiguous in projection. However, the flower ...
    • Automatic Generation of Tourist Brochures 

      Birsak, Michael; Musialski, Przemyslaw; Wonka, Peter; Wimmer, Michael (The Eurographics Association and John Wiley and Sons Ltd., 2014)
