Hele-Shaw Flow Simulation with Interactive Control using Complex Barycentric Coordinates
(The Eurographics Association, 2016)Hele-Shaw flow describes the slow flow of a viscous liquid between two parallel plates separated by a small gap. In some configurations such a flow generates instabilities known as Saffman-Taylor fingers, which form intricate ... -
Two-way Coupling of Fluids to Reduced Deformable Bodies
(The Eurographics Association, 2016)We propose a fully monolithic two-way coupling framework that couples incompressible fluids to reduced deformable bodies. Notably, the resulting linear system matrix is both symmetric and positive-definite. Our method ... -
Versatile Interactions at Interfaces for SPH-Based Simulations
(The Eurographics Association, 2016)The realistic capture of various interactions at interfaces is a challenging problem for SPH-based simulation. Previous works have mainly considered a single type of interaction, while real-world phenomena typically exhibit ... -
Constrained Neighbor Lists for SPH-based Fluid Simulations
(The Eurographics Association, 2016)In this paper we present a new approach to create neighbor lists with strict memory bounds for incompressible Smoothed Particle Hydrodynamics (SPH) simulations. Our proposed approach is based on a novel efficient ... -
Topology-Aware Neighborhoods for Point-Based Simulation and Reconstruction
(The Eurographics Association, 2016)Particle based simulations are widely used in computer graphics. In this field, several recent results have improved the simulation itself or improved the tension of the final fluid surface. In current particle based ... -
Enriching SPH Simulation by Approximate Capillary Waves
(The Eurographics Association, 2016)Capillary waves are di cult to simulate due to their fast traveling speed and high frequency. In this paper, we propose to approximate capillary wave e ects by surface compression waves under the SPH framework. To achieve ... -
ADMM ⊇ Projective Dynamics: Fast Simulation of General Constitutive Models
(The Eurographics Association, 2016)We apply the alternating direction method of multipliers (ADMM) optimization algorithm to implicit time integration of elastic bodies, and show that the resulting method closely relates to the recently proposed projective ... -
A Macroblock Optimization for Grid-based Nonlinear Elasticity
(The Eurographics Association, 2016)We introduce a new numerical approach for the solution of grid-based discretizations of nonlinear elastic models. Our method targets the linearized system of equations within each iteration of the Newton method, and combines ... -
Asynchronous Implicit Backward Euler Integration
(The Eurographics Association, 2016)In standard deformable object simulation in computer animation, all the mesh elements or vertices are timestepped synchronously, i.e., under the same timestep. Previous asynchronous methods have been largely limited to ... -

Creature Features: Online motion puppetry for non-human characters
(ACM SIGGRAPH / Eurographics Association, 2013)We present a novel real-time motion puppetry system that drives the motion of non-human characters using human motion input. We aim to control a variety of creatures whose body structures and motion patterns can differ ... -
Modeling and Animating Myriapoda: A Real-Time Kinematic/Dynamic Approach
(ACM SIGGRAPH / Eurographics Association, 2013)Unlike two, four, six, and eight legged animals, Myriapoda-i.e., centipedes, millipedes, etc.-have been largely overlooked in the computer graphics literature. We present an artificial life framework for modeling these ... -
Accurate Surface Embedding for Higher Order Finite Elements
(ACM SIGGRAPH / Eurographics Association, 2013)In this paper we present a novel approach to efficiently simulate the deformation of highly detailed meshes using higher order finite elements (FE). An efficient algorithm based on non-linear optimization is proposed in ... -
A Level Set Method for Ductile Fracture
(ACM SIGGRAPH / Eurographics Association, 2013)We utilize the shape derivative of the classical Griffith's energy in a level set method for the simulation of dynamic ductile fracture. The level set is defined in the undeformed configuration of the object, and its ... -
Fast Deformation of Volume Data Using Tetrahedral Mesh Rasterization
(ACM SIGGRAPH / Eurographics Association, 2013)Many inherently deformable structures, such as human anatomy, are often represented using a regular volumetric discretization, e.g., in medical imaging. While deformation algorithms employ discretizations that deform ... -
Geodesic Voxel Binding for Production Character Meshes
(ACM SIGGRAPH / Eurographics Association, 2013)We propose a fully automatic method for specifying influence weights for closed-form skinning methods, such as linear blend skinning. Our method is designed to work with production meshes that may contain non-manifold ... -
Efficient Simulation of Secondary Motion in Rig-Space
(ACM SIGGRAPH / Eurographics Association, 2013)We present an efficient method for augmenting keyframed character animations with physically-simulated secondary motion. Our method achieves a performance improvement of one to two orders of magnitude over previous work ... -
Differential Blending for Expressive Sketch-Based Posing
(ACM SIGGRAPH / Eurographics Association, 2013)Generating highly expressive and caricatured poses can be difficult in 3D computer animation because artists must interact with characters indirectly through complex character rigs. Furthermore, since caricatured poses ... -
One-to-Many: Example-Based Mesh Animation Synthesis
(ACM SIGGRAPH / Eurographics Association, 2013)We propose an example-based approach for synthesizing diverse mesh animations. Provided a short clip of deformable mesh animation, our method synthesizes a large number of different animations of arbitrary length. Combining ... -
SPREAD : Sound Propagation and Perception for Autonomous Agents in Dynamic Environments
(ACM SIGGRAPH / Eurographics Association, 2013)The perception of sensory information and its impact on behavior is a fundamental component of being human. While visual perception is considered for navigation, collision, and behavior selection, the acoustic domain is ...
