    • EigenFit for Consistent Elastodynamic Simulation Across Mesh Resolution 

      Chen, Yu Ju (Edwin); Levin, David I. W.; Kaufmann, Danny; Ascher, Uri; Pai, Dinesh K. (ACM, 2019)
      Elastodynamic system simulation is a key procedure in computer graphics and robotics applications. To enable these simulations, the governing differential system is discretized in space (employing FEM) and then in time. ...
    • Subspace Neural Physics: Fast Data-Driven Interactive Simulation 

      Holden, Daniel; Duong, Bang Chi; Datta, Sayantan; Nowrouzezahrai, Derek (ACM, 2019)
      Data-driven methods for physical simulation are an attractive option for interactive applications due to their ability to trade precomputation and memory footprint in exchange for improved runtime performance. Yet, existing ...
    • A Robust Volume Conserving Method for Character-Water Interaction 

      Lee, Minjae; Hyde, David; Li, Kevin; Fedkiw, Ronald (ACM, 2019)
      We propose a novel volume conserving framework for character- water interaction, using a novel volume-of-fluid solver on a skinned tetrahedral mesh, enabling the high degree of the spatial adaptiv- ity in order to capture ...
    • Proceedings Information SCA 2019 

      Batty, Christopher and Huang, Jin (ACM, 2019)
    • Human Articular Movement Algorithm to Simulate Muscle Contraction and Embedded Tissue Deformation 

      Atsumi, Noritoshi; Kato, Daichi; Hirabayashi, Satoko; Nakahira, Yuko; Iwamoto, Masami (ACM, 2019)
      The visualization of human articular movements associated with internal deformation is critical for many fields including biome- chanics. In this work, we present a novel algorithm to describe realistic articular movement ...
    • Interaction Motion Retargeting to Highly Dissimilar Furniture Environment 

      Jin, Taeil; Lee, Sung-Hee (ACM, 2019)
      Retageting a human-environment interaction motion to a different environment remains as an important research topic in computer animation. This paper introduces a novel method that can retarget an interaction motion to ...
    • GPU-Based Contact-Aware Trajectory Optimization Using A Smooth Force Model 

      Pan, Zherong; Ren, Bo; Manocha, Dinesh (ACM, 2019)
      We present a new formulation of trajectory optimization for articulated bodies. Our approach uses a fully differentiable dynamic model of the articulated body, and a smooth force model that approximates all kinds of ...
    • Online Motion Synthesis Framework using a Simple Mass Model based on Predictive Coding 

      Hwang, Jaepyung; Ishii, Shin; Oba, Shigeyuki (ACM, 2019)
      Hybrid-based character animation utilizing the motion capture data and a simplified physics model allows synthesizing the motion data without losing its naturalness of the original motion. However, using both the physical ...
    • Fast Simulation of Deformable Characters with Articulated Skeletons in Projective Dynamics 

      Li, Jing; Liu, Tiantian; Kavan, Ladislav (ACM, 2019)
      We propose a fast and robust solver to simulate continuum-based deformable models with constraints, in particular, rigid-body and joint constraints useful for soft articulated characters. Our method embeds degrees of freedom ...
    • Divergence-Free and Boundary-Respecting Velocity Interpolation Using Stream Functions 

      Chang, Jumyung; Azevedo, Vinicius C.; Batty, Christopher (ACM, 2019)
      In grid-based fluid simulation, discrete incompressibility of each cell is enforced by the pressure projection. However, pointwise velocities constructed by interpolating the discrete velocity samples from the staggered ...
    • Small Steps in Physics Simulation 

      Macklin, Miles; Storey, Kier; Lu, Michelle; Terdiman, Pierre; Chentanez, Nuttapong; Jeschke, Stefan; Müller, Matthias (ACM, 2019)
      In this paper we re-examine the idea that implicit integrators with large time steps offer the best stability/performance trade-off for stiff systems. We make the surprising observation that performing a single large time ...
