Sheldon Andrews, Marek Teichmann, Paul Kry This paper focuses on the stable and efficient simulation of articulated rigid body systems for real-time applications. Specifically, we focus on the use of geometric stiffness, which can dramatically increase simulation stability. We examine … Continue reading →

Alexey Stomakhin, Andrew Selle We present a novel approach to guiding physically based particle simulations using boundary conditions. Unlike commonly used ad hoc particle techniques for adding and removing the material from a simulation, our approach is principled by utilizing … Continue reading →

Tiantian Liu, Sofien Bouaziz, Ladislav Kavan We present a new method for real-time physics-based simulation supporting many different types of hyperelastic materials. Previous methods such as Position Based or Projective Dynamics are fast, but support only limited selection of materials; … Continue reading →

Density Maps for Improved SPH Boundary Handling Fully Asynchronous SPH Simulation Evaporation and Condensation of SPH-based Fluids A Micropolar Material Model for Turbulent SPH Fluids Physically-Based Droplet Interaction Hierarchical Vorticity Skeletons A Positive-Definite Cut-Cell Method for Strong Two-Way Coupling Between … Continue reading →

Chenfanfu Jiang, Theodore Gast, Joseph Teran The typical elastic surface or curve simulation method takes a Lagrangian approach and consists of three components: time integration, collision detection and collision response. The Lagrangian view is beneficial because it naturally allows for … Continue reading →

Desai Chen, David I. W. Levin, Wojciech Matusik, Danny M. Kaufman The realistic simulation of highly-dynamic elastic objects is important for a broad range of applications in computer graphics, engineering and computational fabrication. However, whether simulating flipping toys, jumping robots, prosthetics … Continue reading →

Guillaume Cordonnier, Eric Galin, James Gain, Bedrich Benes, Eric Guérin, Adrien Peytavie, Marie-Paule Cani We introduce a novel framework for interactive landscape authoring that supports bi-directional feedback between erosion and vegetation simulation. Vegetation and terrain erosion have strong mutual impact … Continue reading →

Meekyoung Kim, Gerard Pons-Moll, Sergi Pujades, Sungbae Bang, Jinwwok Kim, Michael Black, Sung-Hee Lee Data driven models of human poses and soft-tissue deformations can produce very realistic results, but they only model the visible surface of the human body and … Continue reading →

Fernando de Goes, Doug L. James We introduce a new technique for real-time physically based volume sculpting of virtual elastic materials. Our formulation is based on the elastic response to localized force distributions associated with common modeling primitives such as … Continue reading →

Jui-Hsien Wang, Rajsekhar Setaluri, Dinesh K Pai, Doug L James We present a novel method to enrich standard rigid-body impact models with a spatially varying coefficient of restitution map, or Bounce Map. Even state-of-the art methods in computer graphics assume … Continue reading →
