      Chentanez, Nuttapong; Müller, Matthias; Macklin, Miles (The Eurographics Association, 2016)
      Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until ...

      Kugelstadt, Tassilo; Schömer, Elmar (The Eurographics Association, 2016)
      We present a novel method to simulate bending and torsion of elastic rods within the position-based dynamics (PBD) framework. The main challenge is that torsion effects of Cosserat rods are described in terms of material ...
    • Repurposing Hand Animation for Interactive Applications 

      Bailey, Stephen W.; Watt, Martin; O'Brien, James F. (The Eurographics Association, 2016)
      In this paper we describe a method for automatically animating interactive characters based on an existing corpus of key-framed hand-animation. The method learns separate low-dimensional embeddings for subsets of the ...
    • SCA 2016: Frontmatter 

      Ladislav Kavan; Chris Wojtan (Eurographics Association, 2016)
    • Constrained Neighbor Lists for SPH-based Fluid Simulations 

      Winchenbach, Rene; Hochstetter, Hendrik; Kolb, Andreas (The Eurographics Association, 2016)
      In this paper we present a new approach to create neighbor lists with strict memory bounds for incompressible Smoothed Particle Hydrodynamics (SPH) simulations. Our proposed approach is based on a novel efficient ...

      Bi, Huikun; Mao, Tianlu; Wang, Zhaoqi; Deng, Zhigang (The Eurographics Association, 2016)
      In this paper, we propose a new data-driven model to simulate the process of lane-changing in traffic simulation. Specifically, we first extract the features from surrounding vehicles that are relevant to the lane-changing ...

      Koschier, Dan; Deul, Crispin; Bender, Jan (The Eurographics Association, 2016)
      In this paper we propose a novel method to construct hierarchical hp-adaptive Signed Distance Fields (SDFs). We discretize the signed distance function of an input mesh using piecewise polynomials on an axis-aligned ...
    • Asynchronous Implicit Backward Euler Integration 

      Zhao, Danyong; Li, Yijing; Barbic, Jernej (The Eurographics Association, 2016)
      In standard deformable object simulation in computer animation, all the mesh elements or vertices are timestepped synchronously, i.e., under the same timestep. Previous asynchronous methods have been largely limited to ...
    • Large-Scale Finite State Game Engines

      Yamamoto, Kazuhiko; Igarashi, Takeo (The Eurographics Association, 2016)
      Physically-based sound rendering enriches 3D animation. However, it is difficult to make an object with a given shape produce a specific sound using physically-based sound rendering because the user would need to define ...
