    • Quaternion Space Sparse Decomposition for Motion Compression and Retrieval 

      Zhu, Mingyang; Sun, Huaijiang; Deng, Zhigang (The Eurographics Association, 2012)
      Quaternion has become one of the most widely used representations for rotational transformations in 3D graphics for decades. Due to the sparse nature of human motion in both the spatial domain and the temporal domain, an ...

    • 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 ...

    • Simple Data-Driven Control for Simulated Bipeds 

      Geijtenbeek, T.; Pronost, Nicolas; Stappen, A. F. van der (The Eurographics Association, 2012)
      We present a framework for controlling physics-based bipeds in a simulated environment, based on a variety of reference motions. Unlike existing methods for control based on reference motions, our framework does not require ...

    • 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 ...

    • 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. ...

    • Task-driven Posture Optimization for Virtual Characters 

      Liu, Mingxing; Micaelli, Alain; Evrard, Paul; Escande, Adrien (The Eurographics Association, 2012)
      This paper presents a generic approach to find optimal postures, including contact positions, for manipulation tasks. It can be used in either the preparation for a task, or the evaluation of the feasibility of a task ...

    • 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 ...
