Hybrid Simulation of Deformable Solids
(The Eurographics Association, 2007)
Although mesh-based methods are efficient for simulating simple hyperelasticity, maintaining and adapting a mesh-based representation is less appealing in more complex scenarios, e.g. collision, plasticity and fracture. ...
Simulating Speech with a Physics-Based Facial Muscle Model
(The Eurographics Association, 2006)
We present a physically based system for creating animations of novel words and phrases from text and audio input based on the analysis of motion captured speech examples. Leading image based techniques exhibit photo-real ...
Globally Coupled Collision Handling Using Volume Preserving Impulses
(The Eurographics Association, 2008)
We present a novel algorithm for collision processing on triangulated meshes. Our method robustly maintains a collision free state on complex geometries while resorting to collision resolution at time intervals often ...
Robust Quasistatic Finite Elements and Flesh Simulation
(The Eurographics Association, 2005)
Quasistatic and implicit time integration schemes are typically employed to alleviate the stringent time step restrictions imposed by their explicit counterparts. However, both quasistatic and implicit methods are subject ...
Fast Grid-Based Nonlinear Elasticity for 2D Deformations
(The Eurographics Association, 2014)
We present a deformation technique that constructs 2D warps by using spline curves to specify the starting and target shapes of selected key contours. We generate a two-dimensional deformation map from these contours by ...
Steklov-Poincaré Skinning
(The Eurographics Association, 2014)
We introduce a novel and efficient simulation technique for generating physics-based skinning animations of skeleton-driven characters with full support for collision handling. Although physics-based approaches may use a ...
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 ...
A Parallel Multigrid Poisson Solver for Fluids Simulation on Large Grids
(The Eurographics Association, 2010)
We present a highly efficient numerical solver for the Poisson equation on irregular voxelized domains supporting an arbitrary mix of Neumann and Dirichlet boundary conditions. Our approach employs a multigrid cycle as a ...
Arbitrary Cutting of Deformable Tetrahedralized Objects
(The Eurographics Association, 2007)
We propose a flexible geometric algorithm for placing arbitrary cracks and incisions on tetrahedralized deformable objects. Although techniques based on remeshing can also accommodate arbitrary fracture patterns, this ...
