All the SCA papers , physics-related and otherwise, along with their presentation videos, are on the SCA conference site. (Below I try to link to author pages, as usual.) Distant Collision Response in Rigid Body Simulations A Bending Model for Nodal Discretizations of Yarn-Level Cloth A Hybrid Lagrangian/Eulerian Collocated Velocity Advection and Projection Method for […]

Eulalie Coevoet, Sheldon Andrews, Denali Relles, Paul G. Kry We use a finite element model to predict the vibration response of objects in a rigid body simulation, such that rigid objects are augmented to provide a plausible elastic collision response between distant objects due to vibration. We start with a generalized eigenvalue decomposition of the […]

José M. Pizana, Alejandro Rodríguez, Gabriel Cirio, Miguel A. Otaduy To deploy yarn-level cloth simulations in production environments, it is paramount to design very efficient implementations,which mitigate the cost of the extremely high resolution. To this end, nodal discretizations aligned with the regularity of the fabric structure provide an optimal setting for efficient GPU implementations. […]

Steven Gagniere, David Hyde, Alan Marquez-Razon, Chenfanfu Jiang, Ziheng Ge, Xuchen Han, Qi Guo, Joseph Teran We present a hybrid particle/grid approach for simulating incompressible fluids on collocated velocity grids. Our approach supports both particle-based Lagrangian advection in very detailed regions of the flow and efficient Eulerian grid-based advection in other regions of the flow. […]

Zhiqi Yin, KangKang Yin In physics-based character animation, Proportional-Derivative (PD) controllers are commonly used for tracking reference motions in motor control tasks. Stable PD (SPD) controllers significantly improve the numerical stability of traditional PD controllers and support large gains and large integration time steps during simulation. For an articulated rigid body system with n degrees […]

Theodore Kim The Baraff-Witkin model has been a popular formulation for cloth for 20 years. However, its relationship to the finite element method (FEM) has always been unclear, because the model resists being written as an isotropic, hyperelastic strain energy. In this paper, we show that this is because the Baraff-Witkin model is actually a […]

Cheng Li, Min Tang, Ruofeng Tong, Ming Cai, Jieyi Zhao, Dinesh Manocha We present a novel parallel algorithm for cloth simulation that exploits multiple GPUs for fast computation and the handling of very high resolution meshes. To accelerate implicit integration, we describe new parallel algorithms for sparse matrix-vector multiplication (SpMV) and for dynamic matrix assembly […]

Torsten Hädrich, Miłosz Makowski, Wojtek Pałubicki, Daniel T. Banuti, Soren Pirk, Dominik L. Michels The complex interplay of a number of physical and meteorological phenomena makes simulating clouds a challenging and open research problem. We explore a physically accurate model for simulating clouds and the dynamics of their transitions. We propose first-principle formulations for computing […]

Libo Huang, Dominik L. Michels. We devise a novel surface-only approach for simulating the three dimensional free-surface flow of incompressible, inviscid, and linearly magnetizable ferrofluids. A Lagrangian velocity field is stored on a triangle mesh capturing the fluid’s surface. The two key problems associated with the dynamic simulation of the fluid’s interesting geometry are the […]

Oscar Argudo, Eric Galin, Adrien Peytavie, Axel Paris, Eric Guerin Glaciers are some of the most visually arresting and scenic elements of cold regions and high mountain landscapes. Although snow-covered terrains have previously received attention in computer graphics, simulating the temporal evolution of glaciers as well as modeling their wide range of features has never […]
