    • Coupling Friction with Visual Appearance 

      Andrews, Sheldon; Nassif, Loic; Erleben, Kenny; Kry, Paul G. (ACM, 2021)
      We present a novel meso-scale model for computing anisotropic and asymmetric friction for contacts in rigid body simulations that is based on surface facet orientations. The main idea behind our approach is to compute a ...

    • Distant Collision Response in Rigid Body Simulations 

      Coevoet, Eulalie; Andrews, Sheldon; Relles, Denali; Kry, Paul G. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We use a finite element model to predict the vibration response of objects in a rigid body simulation, such that rigid objects are augmented to provide a plausible elastic collision response between distant objects due to ...

    • Graph Partitioning Algorithms for Rigid Body Simulations 

      Liu, Yinchu; Andrews, Sheldon (The Eurographics Association, 2022)
      We propose several graph partitioning algorithms for improving the performance of rigid body simulations. The algorithms operate on the graph formed by rigid bodies (nodes) and constraints (edges), producing non-overlapping ...

    • Synthesizing Get-Up Motions for Physics-based Characters 

      Frezzato, Anthony; Tangri, Arsh; Andrews, Sheldon (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      We propose a method for synthesizing get-up motions for physics-based humanoid characters. Beginning from a supine or prone state, our objective is not to imitate individual motion clips, but to produce motions that match ...

    • Too Stiff, Too Strong, Too Smart: Evaluating Fundamental Problems with Motion Control Policies 

      Xie, Kaixiang; Xu, Pei; Andrews, Sheldon; Zordan, Victor B.; Kry, Paul G. (ACM Association for Computing Machinery, 2023)
      Deep reinforcement learning (DRL) methods have demonstrated impressive results for skilled motion synthesis of physically based characters, and while these methods perform well in terms of tracking reference motions or ...

    • VRIPHYS 2018: Frontmatter 

      Andrews, Sheldon; Erleben, Kenny; Jaillet, Fabrice; Zachmann, Gabriel (Eurographics Association, 2018)
