Fully Momentum-Conserving Reduced Deformable Bodies with Collision, Contact, Articulation, and Skinning
(ACM Siggraph, 2015)
We propose a novel framework for simulating reduced deformable bodies that fully accounts for linear and angular momentum conservation even in the presence of collision, contact, articulation, and other desirable effects. ...
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. ...
Accurate Tangential Velocities For Solid Fluid Coupling
(ACM SIGGRAPH / Eurographics Association, 2009)
We propose a novel method for obtaining more accurate tangential velocities for solid fluid coupling. Our method works for both rigid and deformable objects as well as both volumetric objects and thin shells. The fluid can ...
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 ...
Chimera Grids for Water Simulation
(ACM SIGGRAPH / Eurographics Association, 2013)
We introduce a new method for large scale water simulation using Chimera grid embedding, which discretizes space with overlapping Cartesian grids that translate and rotate in order to decompose the domain into different ...
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 ...
Mass and Momentum Conservation for Fluid Simulation
(The Eurographics Association, 2011)
Momentum conservation has long been used as a design principle for solid simulation (e.g. collisions between rigid bodies, mass-spring elastic and damping forces, etc.), yet it has not been widely used for fluid simulation. ...
A Hybrid Lagrangian-Eulerian Formulation for Bubble Generation and Dynamics
(ACM SIGGRAPH / Eurographics Association, 2013)
We present a hybrid Lagrangian-Eulerian framework for simulating both small and large scale bubble dynamics, where the bubbles can grow or shrink in volume as dictated by pressure forces in the surrounding fluid. Small ...
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 ...
Efficient Denting and Bending of Rigid Bodies
(The Eurographics Association, 2014)
We present a novel method for the efficient denting and bending of rigid bodies without the need for expensive finite element simulations. Denting is achieved by deforming the triangulated surface of the target body based ...
