Vinicius C. Azevedo, Christopher Batty, Manuel M. Oliveira Fluid animation methods based on Eulerian grids have long struggled to resolve flows involving narrow gaps and thin solid features. Past approaches have artificially inflated or voxelized boundaries, although this sacrifices the … Continue reading →

Xiao Yan, Yun-Tao Jiang, Chen-Feng Li, Ralph R. Martin, and Shi-Min Hu This work extends existing multiphase-fluid SPH frameworks to cover solid phases, including deformable bodies and granular materials. In our extended multiphase SPH framework, the distribution and shapes of … Continue reading →

Camille Schreck, Damien Rohmer, Stefanie Hahmann, Marie-Paule Cani, Shuo Jin, Charlie Wang, Jean-Francois Bloch We present the first method to animate sheets of paper at interactive rates, while automatically generating a plausible set of sharp features when the sheet is … Continue reading →

Albert Chern, Felix Knoppel, Ulrich Pinkall, Peter Schröder, Steffen Weissmann We describe a new approach for the purely Eulerian simulation of incompressible fluids. In it, the fluid state is represented by a ℂ²-valued wave function evolving under the Schrödinger equation … Continue reading →

Morten Bojsen-Hansen, Chris Wojtan When aiming to seamlessly integrate a fluid simulation into a larger scenario (like an open ocean), careful attention must be paid to boundary conditions. In particular, one must implement special “non-reflecting” boundary conditions, which dissipate out-going … Continue reading →

Ben Jones, Nils Thuerey, Tamar Shinar, Adam W. Bargteil Physics-based animation is often used to animate scenes containing destruction of near-rigid, man-made materials. For these applications, the most important visual features are plastic deformation and fracture. Methods based on continuum … Continue reading →

David Hahn, Chris Wojtan We present a boundary element based method for fast simulation of brittle fracture. By introducing simplifying assumptions that allow us to quickly estimate stress intensities and opening displacements during crack propagation, we build a fracture algorithm … Continue reading →

Gilles Daviet, Florence Bertails-Descoubes We present a new continuum-based method for the realistic simulation of large-scale free-flowing granular materials. We derive a compact model for the rheology of the material, which accounts for the exact nonsmooth Drucker-Prager yield criterion combined … Continue reading →

Hongyi Xu, Jernej Barbic We enrich character animations with secondary soft-tissue Finite Element Method (FEM) dynamics computed under arbitrary rigged or skeletal motion. Our method optionally incorporates pose-space deformation (PSD). It runs at milliseconds per frame for complex characters, and … Continue reading →

Aric Bartle, Alla Sheffer, Vladimir G. Kim, Danny Kaufman, Nicholas Vining, Floraine Berthouzoz Designers frequently reuse existing designs as a starting point for creating new garments. In order to apply garment modifications, which the designer envisions in 3D, existing tools require meticulous manual … Continue reading →
