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 ...
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 ...
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 ...
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. ...
Density Maps for Improved SPH Boundary Handling
(ACM, 2017)
In this paper, we present the novel concept of density maps for robust handling of static and rigid dynamic boundaries in fluid simulations based on Smoothed Particle Hydrodynamics (SPH). In contrast to the vast majority ...
Evaporation and Condensation of SPH-based Fluids
(ACM, 2017)
In this paper we present a method to simulate evaporation and condensation of liquids. Therefore, both the air and liquid phases have to be simulated. We use, as a carrier of vapor, a coarse grid for the air phase and ...
A Micropolar Material Model for Turbulent SPH Fluids
(ACM, 2017)
In this paper we introduce a novel micropolar material model for the simulation of turbulent inviscid fluids. The governing equations are solved by using the concept of Smoothed Particle Hydrodynamics (SPH). As already ...
