    • Fast and Robust Inversion-Free Shape Manipulation 

      Liu, Tiantian; Gao, Ming; Zhu, Lifeng; Sifakis, Eftychios; Kavan, Ladislav (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a shape manipulation technique capable of producing deformations of 2D and 3D meshes, guaranteeing that no elements will be inverted. We achieve this by augmenting the quadratic ex-rotated elastic energy with ...
    • General Projective Maps for Multidimensional Data Projection 

      Lehmann, Dirk J.; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      To project high-dimensional data to a 2D domain, there are two well-established classes of approaches: RadViz and Star Coordinates. Both are well-explored in terms of accuracy, completeness, distortions, and interaction ...
    • Generalized As-Similar-As-Possible Warping with Applications in Digital Photography 

      Chen, Renjie; Gotsman, Craig (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Discrete conformal mappings of planar triangle meshes, also known as the As-Similar-As-Possible (ASAP) mapping, involve the minimization of a quadratic energy function, thus are very easy to generate and are popular in ...
    • Generalized Diffusion Curves: An Improved Vector Representation for Smooth-Shaded Images 

      Jeschke, Stefan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper generalizes the well-known Diffusion Curves Images (DCI), which are composed of a set of Bezier curves with colors specified on either side. These colors are diffused as Laplace functions over the image domain, ...
    • Geometric Flows of Curves in Shape Space for Processing Motion of Deformable Objects 

      Brandt, Christopher; Tycowicz, Christoph von; Hildebrandt, Klaus (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We introduce techniques for the processing of motion and animations of non-rigid shapes. The idea is to regard animations of deformable objects as curves in shape space. Then, we use the geometric structure on shape space ...
    • Geometry and Attribute Compression for Voxel Scenes 

      Dado, Bas; Kol, Timothy R.; Bauszat, Pablo; Thiery, Jean-Marc; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Voxel-based approaches are today's standard to encode volume data. Recently, directed acyclic graphs (DAGs) were successfully used for compressing sparse voxel scenes as well, but they are restricted to a single bit of ...
    • Improved Surface Quality in 3D Printing by Optimizing the Printing Direction 

      Wang, Weiming; Zanni, Cédric; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a pipeline of algorithms that decomposes a given polygon model into parts such that each part can be 3D printed with high (outer) surface quality. For this we exploit the fact that most 3D printing technologies ...
    • Inertial Steady 2D Vector Field Topology 

      Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Vector field topology is a powerful and matured tool for the study of the asymptotic behavior of tracer particles in steady flows. Yet, it does not capture the behavior of finite-sized particles, because they develop inertia ...
    • Interactive Videos: Plausible Video Editing using Sparse Structure Points 

      Chang, Chia-Sheng; Chu, Hung-Kuo; Mitra, Niloy J. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Video remains the method of choice for capturing temporal events. However, without access to the underlying 3D scene models, it remains difficult to make object level edits in a single video or across multiple videos. While ...
    • Large Scale Terrain Generation from Tectonic Uplift and Fluvial Erosion 

      Cordonnier, Guillaume; Braun, Jean; Cani, Marie-Paule; Benes, Bedrich; Galin, Éric; Peytavie, Adrien; Guérin, Éric (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      At large scale, landscapes result from the combination of two major processes: tectonics which generate the main relief through crust uplift, and weather which accounts for erosion. This paper presents the first method in ...
    • Learning 3D Deformation of Animals from 2D Images 

      Kanazawa, Angjoo; Kovalsky, Shahar; Basri, Ronen; Jacobs, David (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Understanding how an animal can deform and articulate is essential for a realistic modification of its 3D model. In this paper, we show that such information can be learned from user-clicked 2D images and a template 3D ...
    • Modeling and Estimation of Energy-Based Hyperelastic Objects 

      Miguel, Eder; Miraut, David; Otaduy, Miguel A. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we present a method to model hyperelasticity that is well suited for representing the nonlinearity of real-world objects, as well as for estimating it from deformation examples. Previous approaches suffer ...
    • Motion Grammars for Character Animation 

      Hyun, Kyunglyul; Lee, Kyungho; Lee, Jehee (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The behavioral structure of human movements is imposed by multiple sources, such as rules, regulations, choreography, habits, and emotion. Our goal is to identify the behavioral structure in a specific application domain ...
    • Multi-Resolution Meshes for Feature-Aware Hardware Tessellation 

      Lambert, Thibaud; Bénard, Pierre; Guennebaud, Gaël (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Hardware tessellation is de facto the preferred mechanism to adaptively control mesh resolution with maximal performances. However, owing to its fixed and uniform pattern, leveraging tessellation for feature-aware LOD ...
    • A Multi-sided Bézier Patch with a Simple Control Structure 

      Várady, Tamás; Salvi, Péter; Karikó, György (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      A new n-sided surface scheme is presented, that generalizes tensor product Bézier patches. Boundaries and corresponding crossderivatives are specified as conventional Bézier surfaces of arbitrary degrees. The surface is ...
    • Multisampling Compressive Video Spectroscopy 

      Jeon, Daniel S.; Choi, Inchang; Kim, Min H. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The coded aperture snapshot spectral imaging (CASSI) architecture has been employed widely for capturing hyperspectral video. Despite allowing concurrent capture of hyperspectral video, spatial modulation in CASSI sacrifices ...
