    • Adapting Feature Curve Networks to a Prescribed Scale 

      Gehre, Anne; Lim, Isaak; Kobbelt, Leif (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Feature curves on surface meshes are usually defined solely based on local shape properties such as dihedral angles and principal curvatures. From the application perspective, however, the meaningfulness of a network of ...
    • Near-Instant Capture of High-Resolution Facial Geometry and Reflectance

      We present a near-instant method for acquiring facial geometry and reflectance using a set of commodity DSLR cameras and flashes. Our setup consists of twenty-four cameras and six flashes which are fired in rapid succession ...
    • Compressed Multiresolution Hierarchies for High-Quality Precomputed Shadows 

      Scandolo, Leonardo; Bauszat, Pablo; Eisemann, Elmar (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The quality of shadow mapping is traditionally limited by texture resolution. We present a novel lossless compression scheme for high-resolution shadow maps based on precomputed multiresolution hierarchies. Traditional ...
    • 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 ...
    • BlendForces: A Dynamic Framework for Facial Animation 

      Barrielle, Vincent; Stoiber, Nicolas; Cagniart, Cédric (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper we present a new paradigm for the generation and retargeting of facial animation. Like a vast majority of the approaches that have adressed these topics, our formalism is built on blendshapes. However, where ...
    • A Practical and Controllable Hair and Fur Model for Production Path Tracing 

      Chiang, Matt Jen-Yuan; Bitterli, Benedikt; Tappan, Chuck; Burley, Brent (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present an energy-conserving fiber shading model for hair and fur that is efficient enough for path tracing. Our model adopts a near-field formulation to avoid the expensive integral across the fiber, accounts for all ...
    • Regularizing Image Reconstruction for Gradient-Domain Rendering with Feature Patches 

      Manzi, Marco; Vicini, Delio; Zwicker, Matthias (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel algorithm to reconstruct high-quality images from sampled pixels and gradients in gradient-domain rendering. Our approach extends screened Poisson reconstruction by adding additional regularization ...
    • SAH Guided Spatial Split Partitioning for Fast BVH Construction 

      Ganestam, Per; Doggett, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatially coherent triangles. Our triangle split approach is integrated into the partitioning stage ...
    • 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 ...
    • EUROGRAPHICS 2016: CGF 35-2 Frontmatter 

      Joaquim Jorge; Ming Lin (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    • Effect of Low-level Visual Details in Perception of Deformation 

      Han, Donghui; Keyser, John (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We quantitatively measure how different low-level visual details can influence people's perceived stiffness of a deformable sphere under physically based simulation. The result can be used to create a metric for artists ...
    • 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 ...
    • Animation Setup Transfer for 3D Characters 

      Avril, Quentin; Ghafourzadeh, Donya; Ramachandran, Srinivasan; Fallahdoust, Sahel; Ribet, Sarah; Dionne, Olivier; Lasa, Martin de; Paquette, Eric (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a general method for transferring skeletons and skinning weights between characters with distinct mesh topologies. Our pipeline takes as inputs a source character rig (consisting of a mesh, a transformation ...
    • Character Contact Re-positioning Under Large Environment Deformation 

      Tonneau, Steve; Al-Ashqar, Rami Ali; Pettré, Julien; Komura, Taku; Mansard, Nicolas (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Character animation based on motion capture provides intrinsically plausible results, but lacks the flexibility of procedural methods. Motion editing methods partially address this limitation by adapting the animation to ...
    • An Objective Deghosting Quality Metric for HDR Images 

      Tursun, Okan Tarhan; Akyüz, Ahmet Oğuz; Erdem, Aykut; Erdem, Erkut (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Reconstructing high dynamic range (HDR) images of a complex scene involving moving objects and dynamic backgrounds is prone to artifacts. A large number of methods have been proposed that attempt to alleviate these artifacts, ...
    • Convolutional Sparse Coding for High Dynamic Range Imaging 

      Serrano, Ana; Heide, Felix; Gutierrez, Diego; Wetzstein, Gordon; Masia, Belen (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Current HDR acquisition techniques are based on either (i) fusing multibracketed, low dynamic range (LDR) images, (ii) modifying existing hardware and capturing different exposures simultaneously with multiple sensors, or ...
    • Data-guided Model Predictive Control Based on Smoothed Contact Dynamics 

      Han, Daseong; Eom, Haegwang; Noh, Junyong; Shin, Joseph S. (formerly Sung Yong) (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we propose an efficient data-guided method based on Model Predictive Control (MPC) to synthesize a full-body motion. Guided by a reference motion, our method repeatedly plans the full-body motion to produce ...

      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, ...
