    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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. ...
