Interaction Motion Retargeting to Highly Dissimilar Furniture Environment
(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 ... -
Subspace Neural Physics: Fast Data-Driven Interactive Simulation
(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
(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. ... -
GPU-Based Contact-Aware Trajectory Optimization Using A Smooth Force Model
(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 ... -
A Robust Volume Conserving Method for Character-Water Interaction
(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 ... -
Small Steps in Physics Simulation
(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 ... -
Fast Simulation of Deformable Characters with Articulated Skeletons in Projective Dynamics
(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 ... -

Modeling and Data-Driven Parameter Estimation for Woven Fabrics
(ACM, 2017)Accurate estimation of mechanical parameters for simulation of woven fabrics is essential in many fields. To facilitate this we first present a new orthotropic hyperelastic constitutive model for woven fabrics. Next, we ... -
Inequality Cloth
(ACM, 2017)As has been noted and discussed by various authors, numerical simulations of deformable bodies often adversely suffer from so-called ''locking'' artifacts. We illustrate that the ''locking'' of out-of-plane bending motion ... -
Designing Cable-Driven Actuation Networks for Kinematic Chains and Trees
(ACM, 2017)In this paper we present an optimization-based approach for the design of cable-driven kinematic chains and trees. Our system takes as input a hierarchical assembly consisting of rigid links jointed together with hinges. ... -
Long Range Constraints for Rigid Body Simulations
(ACM, 2017)The two main constraints used in rigid body simulations are contacts and joints. Both constrain the motion of a small number of bodies in close proximity. However, it is often the case that a series of constraints restrict ... -
Rigid Body Contact Problems using Proximal Operators
(ACM, 2017)Iterative methods are popular for solving contact force problems in rigid body dynamics. They are loved for their robustness and surrounded by mystery as to whether they converge or not. We provide a mathematical foundation ... -
Learning Locomotion Skills Using DeepRL: Does the Choice of Action Space Matter?
(ACM, 2017)The use of deep reinforcement learning allows for high-dimensional state descriptors, but little is known about how the choice of action representation impacts learning and the resulting performance. We compare the impact ... -
Augmenting Sampling Based Controllers with Machine Learning
(ACM, 2017)E cient learning of 3D character control still remains an open problem despite of the remarkable recent advances in the field. We propose a new algorithm that combines planning by a samplingbased model-predictive controller ... -
Production-Level Facial Performance Capture Using Deep Convolutional Neural Networks
(ACM, 2017)We present a real-time deep learning framework for video-based facial performance capture-the dense 3D tracking of an actor's face given a monocular video. Our pipeline begins with accurately capturing a subject using a ... -
Emotion Control of Unstructured Dance Movements
(ACM, 2017)Motion capture technology has enabled the acquisition of high quality human motions for animating digital characters with extremely high fidelity. However, despite all the advances in motion editing and synthesis, it remains ... -
Authoring Motion Cycles
(ACM, 2017)Motion cycles play an important role in animation production and game development. However, creating motion cycles relies on general-purpose animation packages with complex interfaces that require expert training. Our work ... -
A Positive-Definite Cut-Cell Method for Strong Two-Way Coupling Between Fluids and Deformable Bodies
(ACM, 2017)We present a new approach to simulation of two-way coupling between inviscid free surface fluids and deformable bodies that exhibits several notable advantages over previous techniques. By fully incorporating the dynamics ... -
Hierarchical Vorticity Skeletons
(ACM, 2017)We propose a novel method to extract hierarchies of vortex filaments from given three-dimensional flow velocity fields. We call these collections of filaments Hierarchical Vorticity Skeletons (HVS). They extract multi-scale ...
