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 ... -
A Hybrid Lagrangian/Eulerian Collocated Velocity Advection and Projection Method for Fluid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a hybrid particle/grid approach for simulating incompressible fluids on collocated velocity grids. Our approach supports both particle-based Lagrangian advection in very detailed regions of the flow and efficient ... -
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, ... -
Intuitive Facial Animation Editing Based On A Generative RNN Framework
(The Eurographics Association and John Wiley & Sons Ltd., 2020)For the last decades, the concern of producing convincing facial animation has garnered great interest, that has only been accelerating with the recent explosion of 3D content in both entertainment and professional activities. ... -
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 ... -
Making Procedural Water Waves Boundary-aware
(The Eurographics Association and John Wiley & Sons Ltd., 2020)The ''procedural'' approach to animating ocean waves is the dominant algorithm for animating larger bodies of water in interactive applications as well as in off-line productions - it provides high visual quality with a ... -
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 ... -
A Pixel-Based Framework for Data-Driven Clothing
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We propose a novel approach to learning cloth deformation as a function of body pose, recasting the graph-like triangle mesh data structure into image-based data in order to leverage popular and well-developed convolutional ... -
Primal/Dual Descent Methods for Dynamics
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We examine the relationship between primal, or force-based, and dual, or constraint-based formulations of dynamics. Variational frameworks such as Projective Dynamics have proved popular for deformable simulation, however ... -
Probabilistic Character Motion Synthesis using a Hierarchical Deep Latent Variable Model
(The Eurographics Association and John Wiley & Sons Ltd., 2020)We present a probabilistic framework to generate character animations based on weak control signals, such that the synthesized motions are realistic while retaining the stochastic nature of human movement. The proposed ... -

Statistics-based Motion Synthesis for Social Conversations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Plausible conversations among characters are required to generate the ambiance of social settings such as a restaurant, hotel lobby, or cocktail party. In this paper, we propose a motion synthesis technique that can rapidly ...
