Divergence-Free SPH for Incompressible and Viscous Fluids

Posted on October 16, 2016 by christopherbatty

Jan Bender, Dan Koschier In this paper we present a novel Smoothed Particle Hydrodynamics (SPH) method for the efficient and stable simulation of incompressible fluids. The most efficient SPH-based approaches enforce incompressibility either on position or velocity level. However, the … Continue reading →

Reconstructing Personalized Anatomical Models for Physics-based Body Animation

Posted on October 11, 2016 by christopherbatty

Petr Kadlecek, Alexandru-Eugen Ichim, Tiantian Liu, Ladislav Kavan, Jaroslav Krivanek We present a method to create personalized anatomical models ready for physics-based animation, using only on a set of surface 3D scans. We start by building a template anatomical model of an average male … Continue reading →

SMASH: Physics-guided Reconstruction of Collisions from Videos

Posted on October 6, 2016 by christopherbatty

Aron Monszpart, Nils Thuerey, Niloy J. Mitra Collision sequences are commonly used in games and entertainment to add drama and excitement. Authoring even two body collisions in the real world can be difficult, as one has to get timing and the object … Continue reading →

Eulerian Solid-Fluid Coupling

Posted on October 3, 2016 by christopherbatty

Yun Teng, David I.W. Levin, Theodore Kim We present a new method that achieves a two-way coupling between deformable solids and an incompressible fluid where the underlying geometric representation is entirely Eulerian. Using the recently developed Eulerian Solids approach [Levin … Continue reading →

A scalable Schur-complement fluids solver for heterogeneous compute platforms

Posted on October 1, 2016 by christopherbatty

Haixiang Liu, Nathan Mitchell, Mridul Aanjaneya, Eftychios Sifakis We present a scalable parallel solver for the pressure Poisson equation in fluids simulation which can accommodate complex irregular domains in the order of a billion degrees of freedom, using a single … Continue reading →

Vivace: a Practical Gauss-Seidel Method for Stable Soft Body Dynamics

Posted on October 1, 2016 by christopherbatty

Marco Fratarcangeli, Valentina Tibaldo, Fabio Pellacini The solution of large sparse systems of linear constraints is at the base of most interactive solvers for physically-based animation of soft body dynamics. We focus on applications with hard and tight per-frame resource budgets, such … Continue reading →

Descent Methods for Elastic Body Simulation on the GPU

Posted on October 1, 2016 by christopherbatty

Huamin Wang, Yin Yang We show that many existing elastic body simulation approaches can be interpreted as descent methods, under a nonlinear optimization framework derived from implicit time integration. The key question is how to find an effective descent direction … Continue reading →
