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 →

Rene Winchenbach, Henrik Hockstetter, Andreas Kolb In this paper we introduce a novel method to adaptive incompressible SPH simulations. Instead of using a scheme with a number of fixed particle sizes or levels, our approach allows continuous particle sizes. This … Continue reading →

Dominik L. Michels, Vu Thai Luan, Mayya Tokman We present a new integration algorithm for the accurate and efficient solution of stiff elastodynamic problems governed by the second-order ordinary differential equations of structural mechanics. Current methods have the shortcoming that … Continue reading →

Bohan Wang, Yili Zhao, Jernej Barbic Botanical simulation plays an important role in many fields including visual effects, games and virtual reality. Previous plant simulation research has focused on computing physically based motion, under the assumption that the material properties … Continue reading →
