Michael Lentine, Matthew Cong, Saket Patkar, Ron Fedkiw 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 … Continue reading →

Nuttapong Chentanez, Matthias Mueller We present a GPU friendly, Eulerian, free surface fluid simulation method that conserves mass locally and globally without the use of Lagrangian components. Local mass conservation prevents small scale details of the free surface from disappearing, … Continue reading →

Loiez Glondu, Sarah Schvartzman, Maud Marchal, Georges Dumon, Miguel Otaduy In complex scenes with many objects, collision detection plays a key role in the simulation performance. This is particularly true for fracture simulation, where multiple new objects are dynamically created. … Continue reading →

Richard Tonge, Feodor Benevolenski, Andrey Voroshilov We present a parallel iterative rigid body solver that avoids common artifacts at low iteration counts. In large or real-time simulations, iteration is often terminated before convergence to maximize scene size. If the distribution … Continue reading →

Stelian Coros, Sebastian Martin, Bernhard Thomaszewski, Christian Schumacher, Robert Sumner, Markus Gross We present a method for controlling the motions of active deformable characters. As an underlying principle, we require that all motions be driven by internal deformations. We achieve … Continue reading →

Alexey Stomakhin, Russell Howes, Craig Schroeder, Joseph Teran We provide a smooth extension of arbitrary isotropic hyperelastic energy density functions to inverted configurations. This extension is designed to improve robustness for elasticity simulations with extremely large deformations and is analogous to … Continue reading →

Marek Misztal, Kenny Erleben, Adam Bargteil, J. Fursund, Brian Bunch Christensen, Andreas Bærentzen, Robert Bridson 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 (DSC), that … Continue reading →

Tyson Brochu, Todd Keeler, Robert Bridson 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 surface dividing space between … Continue reading →
