    • Parallel BVH Construction using Progressive Hierarchical Refinement 

      Hendrich, Jakub; Meister, Daniel; Bittner, Jiří (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a novel algorithm for construction of bounding volume hierarchies (BVHs) for multi-core CPU architectures. The algorithm constructs the BVH by a divisive top-down approach using a progressively refined cut of ...
    • Performance-Based Biped Control using a Consumer Depth Camera 

      Lee, Yoonsang; Kwon, Taesoo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a technique for controlling physically simulated characters using user inputs from an off-the-shelf depth camera. Our controller takes a real-time stream of user poses as input, and simulates a stream of target ...
    • Practical Capture and Reproduction of Phosphorescent Appearance 

      Nalbach, Oliver; Seidel, Hans-Peter; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
    • Real-Time Multi-View Facial Capture with Synthetic Training 

      Klaudiny, Martin; McDonagh, Steven; Bradley, Derek; Beeler, Thabo; Mitchell, Kenny (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a real-time multi-view facial capture system facilitated by synthetic training imagery. Our method is able to achieve high-quality markerless facial performance capture in real-time from multi-view helmet camera ...
    • ShapeGenetics: Using Genetic Algorithms for Procedural Modeling 

      Haubenwallner, Karl; Seidel, Hans-Peter; Steinberger, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In this paper, we show that genetic algorithms (GA) can be used to control the output of procedural modeling algorithms. We propose an efficient way to encode the choices that have to be made during a procedural generation ...
    • Simulation-Ready Hair Capture 

      Hu, Liwen; Bradley, Derek; Li, Hao; Beeler, Thabo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Physical simulation has long been the approach of choice for generating realistic hair animations in CG. A constant drawback of simulation, however, is the necessity to manually set the physical parameters of the simulation ...
    • Sparse Inertial Poser: Automatic 3D Human Pose Estimation from Sparse IMUs 

      Marcard, Timo von; Rosenhahn, Bodo; Black, Michael J.; Pons-Moll, Gerard (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We address the problem of making human motion capture in the wild more practical by using a small set of inertial sensors attached to the body. Since the problem is heavily under-constrained, previous methods either use a ...
    • Sparse Rig Parameter Optimization for Character Animation 

      Song, Jaewon; Ribera, Roger Blanco i; Cho, Kyungmin; You, Mi; Lewis, J. P.; Choi, Byungkuk; Noh, Junyong (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We propose a novel motion retargeting method that efficiently estimates artist-friendly rig space parameters. Inspired by the workflow typically observed in keyframe animation, our approach transfers a source motion into ...
    • Spatial Adjacency Maps for Translucency Simulation under General Illumination 

      Maisch, Sebastian; Ropinski, Timo (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Rendering translucent materials in real time is usually done by using surface diffusion and/or (translucent) shadow maps. The downsides of these approaches are, that surface diffusion cannot handle translucency effects ...
    • STD: Student's t-Distribution of Slopes for Microfacet Based BSDFs 

      Ribardière, Mickael; Bringier, Benjamin; Meneveaux, Daniel; Simonot, Lionel (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper focuses on microfacet reflectance models, and more precisely on the definition of a new and more general distribution function, which includes both Beckmann's and GGX distributions widely used in the computer ...
    • A Subjective Evaluation of Texture Synthesis Methods 

      Kolár, Martin; Debattista, Kurt; Chalmers, Alan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper presents the results of a user study which quantifies the relative and absolute quality of example-based texture synthesis algorithms. In order to allow such evaluation, a list of texture properties is compiled, ...
    • Texture Stationarization: Turning Photos into Tileable Textures 

      Moritz, Joep; James, Stuart; Haines, Tom S. F.; Ritschel, Tobias; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Texture synthesis has grown into a mature field in computer graphics, allowing the synthesis of naturalistic textures and images from photographic exemplars. Surprisingly little work, however, has been dedicated to ...
    • Unbiased Light Transport Estimators for Inhomogeneous Participating Media 

      Szirmay-Kalos, László; Georgiev, Iliyan; Magdics, Milán; Molnár, Balázs; Légrády, Dávid (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper presents a new stochastic particle model for efficient and unbiased Monte Carlo rendering of heterogeneous participating media. We randomly add and remove material particles to obtain a density with which free ...
    • Zooming on all Actors: Automatic Focus+Context Split Screen Video Generation 

      Kumar, Moneish; Gandhi, Vineet; Ronfard, Rémi; Gleicher, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Recordings of stage performances are easy to capture with a high-resolution camera, but are difficult to watch because the actors' faces are too small. We present an approach to automatically create a split screen video ...
