    • Precomputed Motion Maps for Unstructured Motion Capture 

      Mahmudi, Mentar; Kallmann, Marcelo (The Eurographics Association, 2012)
      We present in this paper a solution for extracting high-quality motions from unstructured motion capture databases at interactive rates. The proposed solution is based on automatically-built motion graphs, and offers two ...
    • Simulating Free Surface Flow with Very Large Time Steps 

      Lentine, Michael; Cong, Matthew; Patkar, Saket; Fedkiw, Ronald (The Eurographics Association, 2012)
      We provide a novel simulation method for incompressible free surface flows that allows for large time steps on the order of 10-40 times bigger than the typical explicit time step restriction would allow. Although semi-Lagrangian ...
    • Tiling Motion Patches 

      Kim, Manmyung; Hwang, Youngseok; Hyun, Kyunglyul; Lee, Jehee (The Eurographics Association, 2012)
      Simulating multiple character interaction is challenging because character actions must be carefully coordinated to align their spatial locations and synchronized with each other. We present an algorithm to create a dense ...
    • Linear-Time Smoke Animation with Vortex Sheet Meshes 

      Brochu, Tyson; Keeler, Todd; Bridson, Robert (The Eurographics Association, 2012)
      We present the first quality physics-based smoke animation method which runs in time approximately linear in the size of the rendered two-dimensional visual detail. Our fundamental representation is a closed triangle mesh ...
    • Multiphase Flow of Immiscible Fluids on Unstructured Moving Meshes 

      Misztal, Marek Krzysztof; Erleben, Kenny; Bargteil, Adam; Fursund, Jens; Christensen, Brian Bunch; Bærentzen, J. Andreas; Bridson, Robert (The Eurographics Association, 2012)
      In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex ...
    • Smoke Sheets for Graph-Structured Vortex Filaments 

      Barnat, Alfred; Pollard, Nancy S. (The Eurographics Association, 2012)
      Smoke is one of the core phenomena which fluid simulation techniques in computer graphics have attempted to capture. It is both well understood mathematically and important in lending realism to computer generated effects. ...
    • Mathematical Analysis on Affine Maps for 2D Shape Interpolation 

      Kaji, Shizuo; Hirose, Sampei; Sakata, Shigehiro; Mizoguchi, Yoshihiro; Anjyo, Ken (The Eurographics Association, 2012)
      This paper gives a simple mathematical framework for 2D shape interpolation methods that preserve rigidity. An interpolation technique in this framework works for given the source and target 2D shapes, which are compatibly ...
    • Efficient Composition for Virtual Camera Control 

      Lino, Christophe; Christie, Marc (The Eurographics Association, 2012)
      Automatically positioning a virtual camera in a 3D environment given the specification of visual properties to be satisfied (on-screen layout of subjects, vantage angles, visibility) is a complex and challenging problem. ...
    • Occlusion-free Camera Control for Multiple Targets 

      Christie, Marc; Normand, Jean-Marie; Olivier, Patrick (The Eurographics Association, 2012)
      Maintaining the visibility of target objects is a fundamental problem in automatic camera control for 3D graphics applications. Practical real-time camera control algorithms generally only incorporate mechanisms for the ...
    • Interactive Steering of Mesh Animations 

      Vögele, Anna; Hermann, Max; Krüger, Björn; Klein, Reinhard (The Eurographics Association, 2012)
      Creating geometrically detailed mesh animations is an involved and resource-intensive process in digital content creation. In this work we present a method to rapidly combine available sparse motion capture data with ...
    • Finger Walking: Motion Editing with Contact-Based Hand Performance 

      Lockwood, Noah; Singh, Karan (The Eurographics Association, 2012)
      We present a system for generating full-body animations from the performance on a touch-sensitive tabletop of ''finger walking'', where two fingers are used to pantomime leg movements. A user study was conducted to explore ...
    • Combining Marker-based Mocap and RGB-D Camera for Acquiring High-fidelity Hand Motion Data 

      Zhao, Wenping; Chai, Jinxiang; Xu, Ying-Qing (The Eurographics Association, 2012)
      Motion capture data has been pivotal to the success of creating realistic animation for human characters. There are a number of public full-body motion databases available, but large and heterogeneous databases for hand ...
    • Energetically Consistent Invertible Elasticity 

      Stomakhin, Alexey; Howes, Russell; Schroeder, Craig; Teran, Joseph M. (The Eurographics Association, 2012)
      We provide a smooth extension of arbitrary isotropic hyperelastic energy density functions to inverted configurations. This extension is designed to improve robustness for elasticity simulations with ex- tremely large ...
    • Real-Time Example-Based Elastic Deformation 

      Koyama, Yuki; Takayama, Kenshi; Umetani, Nobuyuki; Igarashi, Takeo (The Eurographics Association, 2012)
      We present an example-based elastic deformation method that runs in real time. Example-based elastic deformation was originally presented by Martin et al. [MTGG11], where an artist can intuitively control elastic material ...
    • Enriching Coarse Interactive Elastic Objects with High-Resolution Data-Driven Deformations 

      Seiler, Martin; Spillmann, Jonas; Harders, Matthias (The Eurographics Association, 2012)
      Efficient approximate deformation models allow to interactively simulate elastic objects. However, these approaches usually cannot reproduce the complex deformation behavior governed by geometric and material nonlinearities. ...
    • Efficient Simulation of Example-Based Materials 

      Schumacher, Christian; Thomaszewski, Bernhard; Coros, Stelian; Martin, Sebastian; Sumner, Robert; Gross, Markus (The Eurographics Association, 2012)
      We present a new method for efficiently simulating art-directable deformable materials. We use example poses to define subspaces of desirable deformations via linear interpolation. As a central aspect of our approach, we ...
