Energetically Consistent Invertible Elasticity
(The Eurographics Association, 2012)
We provide a smooth extension of arbitrary isotropic hyperelastic energy density functions to inverted configurations. This extension is designed to improve robustness for elasticity simulations with ex- tremely large ...
Linear-Time Smoke Animation with Vortex Sheet Meshes
(The Eurographics Association, 2012)
We present the first quality physics-based smoke animation method which runs in time approximately linear in the size of the rendered two-dimensional visual detail. Our fundamental representation is a closed triangle mesh ...
Simulating Free Surface Flow with Very Large Time Steps
(The Eurographics Association, 2012)
We provide a novel simulation method for incompressible free surface flows that allows for large time steps on the order of 10-40 times bigger than the typical explicit time step restriction would allow. Although semi-Lagrangian ...
Physically Plausible Simulation for Character Animation
(The Eurographics Association, 2012)
Artist-created animated characters can exhibit stylized, engaging behavior, but require considerable effort to construct, while interactive applications require numerous motions and variations to create a dynamic, believable ...
Dynamic Units of Visual Speech
(The Eurographics Association, 2012)
We present a new method for generating a dynamic, concatenative, unit of visual speech that can generate realistic visual speech animation. We redefine visemes as temporal units that describe distinctive speech movements ...
Principal Geodesic Dynamics
(The Eurographics Association, 2012)
This paper presents a new integration of a data-driven approach using dimension reduction and a physicallybased simulation for real-time character animation. We exploit Lie group statistical analysis techniques (Principal ...
Contact-Invariant Optimization for Hand Manipulation
(The Eurographics Association, 2012)
We present a method for automatic synthesis of dexterous hand movements, given only high-level goals specifying what should happen to the object being manipulated. Results are presented on a wide range of tasks including ...
Component-based Locomotion Composition
(The Eurographics Association, 2012)
When generating locomotion, it is particularly challenging to adjust the motion's style. This paper introduces a component-based system for human locomotion composition that drives off a set of example locomotion clips. ...
Long Range Attachments - A Method to Simulate Inextensible Clothing in Computer Games
(The Eurographics Association, 2012)
Inextensibility is one of the most fundamental properties of cloth. Existing approaches to handle inextensibility often require solving global non-linear systems and remain computationally expensive for computer game uses. ...
Multiphase Flow of Immiscible Fluids on Unstructured Moving Meshes
(The Eurographics Association, 2012)
In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex ...
