ALLSTEPS: Curriculum-driven Learning of Stepping Stone Skills
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Humans are highly adept at walking in environments with foot placement constraints, including stepping-stone scenarios where footstep locations are fully constrained. Finding good solutions to stepping-stone locomotion is ... -
A Bending Model for Nodal Discretizations of Yarn-Level Cloth
(The Eurographics Association and John Wiley & Sons Ltd., 2020)To deploy yarn-level cloth simulations in production environments, it is paramount to design very efficient implementations, which mitigate the cost of the extremely high resolution. To this end, nodal discretizations ... -
Cloth and Skin Deformation with a Triangle Mesh Based Convolutional Neural Network
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We introduce a triangle mesh based convolutional neural network. The proposed network structure can be used for problems where input and/or output are defined on a manifold triangle mesh with or without boundary. We ... -
A Divergence-free Mixture Model for Multiphase Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a novel divergence free mixture model for multiphase flows and the related fluid-solid coupling. The new mixture model is built upon a volume-weighted mixture velocity so that the divergence free condition is ... -
Effective Time Step Restrictions for Explicit MPM Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Time steps for explicit MPM simulation in computer graphics are often selected by trial and error due to the challenges in automatically selecting stable time step sizes. Our time integration scheme uses time step restrictions ... -
Efficient 2D Simulation on Moving 3D Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a method to simulate fluid flow on evolving surfaces, e.g., an oil film on a water surface. Given an animated surface (e.g., extracted from a particle-based fluid simulation) in three-dimensional space, we add ... -
Higher-Order Time Integration for Deformable Solids
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Visually appealing and vivid simulations of deformable solids represent an important aspect of physically based computer animation. For the temporal discretization, it is customary in computer animation to use first-order ... -
Interactive Sound Propagation For Dynamic Scenes Using 2d Wave Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a technique to model wave-based sound propagation to complement visual animation in fully dynamic scenes. We employ 2D wave simulation that captures geometry-based diffraction effects such as obstruction, ... -
Latent Space Subdivision: Stable and Controllable Time Predictions for Fluid Flow
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose an end-to-end trained neural network architecture to robustly predict the complex dynamics of fluid flows with high temporal stability. We focus on single-phase smoke simulations in 2D and 3D based on the ... -
Linear Time Stable PD Controllers for Physics-based Character Animation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)In physics-based character animation, Proportional-Derivative (PD) controllers are commonly used for tracking reference motions in motor control tasks. Stable PD (SPD) controllers significantly improve the numerical stability ... -
Particle-based Liquid Control using Animation Templates
(The Eurographics Association and John Wiley & Sons Ltd., 2020)It is notoriously difficult for artists to control liquids while generating plausible animations. We introduce a new liquid control tool that allows users to load, transform, and apply precomputed liquid simulation templates ...
