Alexander Brown, Gary Ushaw, Graham Morgan In this paper we propose a solution to delivering scalable real-time physics simulations. Although high performance computing simulations of physics related problems do exist, these are not real-time and do not model the real-time … Continue reading →

Ounan Ding, Craig Schroeder We propose a novel penalty force to enforce contacts with accurate Coulomb friction. The force is compatible with fully-implicit time integration and the use of optimization-based integration. The contact force is quite general. In addition to … Continue reading →

Pontus Pall, Oskar Nylèn, Marco Fratarcangeli We introduce a practical iterative solver for mass-spring systems which can be trivially mapped to massively parallel architectures, in particular GPUs.We employ our solver for the interactive animation of virtual cloth and show that … Continue reading →

Jing Li, Tiantian Liu, Ladislav Kavan Damping is an important ingredient in physics-based simulation of deformable objects. Recent work introduced new fast simulation methods such as Position Based Dynamics and Projective Dynamics. Explicit velocity damping methods currently used in conjunction … Continue reading →

Liyou Xu, Xiaowei He, Wei Chen, Sheng Li, and Guoping Wang Peridynamics is a formulation of the classical elastic theory that is targeted at simulating deformable objects with discontinuities, especially fractures. Till now, there are few studies that have been … Continue reading →

George E. Brown, Matthew Overby, Zahra Forootaninia, Rahul Narain We propose a method for accurately simulating dissipative forces in deformable bodies when using optimization-based integrators. We represent such forces using dissipation functions which may be nonlinear in both positions and … Continue reading →

Christoph Gissler, Andreas Peer, Stefan Band, Jan Bender, Matthias Teschner We present a strong fluid-rigid coupling for SPH fluids and rigid bodies with particle-sampled surfaces. The approach interlinks the iterative pressure update at fluid particles with a second SPH solver … Continue reading →

Zhendong Wang, Longhua Wu, Marco Fratarcangeli, Min Tang, Huamin Wang Accurate high-resolution simulation of cloth is a highly desired computational tool in graphics applications. As single resolution simulation starts to reach the limit of computational power, we believe the future … Continue reading →

Mickaël Ly, Romain Casati, Florence Bertails-Descoubes, Mélina Skouras, Laurence Boissieux We propose an inverse strategy for modeling thin elastic shells physically, just from the observation of their geometry. Our algorithm takes as input an arbitrary target mesh, and interprets this … Continue reading →

Omri Azencot, Orestis Vantzos and Mirela Ben-Chen We present a new structure-preserving numerical scheme for solving the Euler–Poincaré Differential (EPDiff) equation on arbitrary triangle meshes. Unlike existing techniques, our method solves the difficult non-linear EPDiff equation by constructing energy preserving, … Continue reading →
