Local Bases for Model-reduced Smoke Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present a flexible model reduction method for simulating incompressible fluids.We derive a novel vector field basis composed of localized basis flows which have simple analytic forms and can be tiled on regular lattices, ...
Displacement-Correlated XFEM for Simulating Brittle Fracture
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present a remeshing-free brittle fracture simulation method under the assumption of quasi-static linear elastic fracture mechanics (LEFM). To achieve this, we devise two algorithms. First, we develop an approximate ...
Asynchronous Eulerian Liquid Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present a novel method for simulating liquid with asynchronous time steps on Eulerian grids. Previous approaches focus on Smoothed Particle Hydrodynamics (SPH), Material Point Method (MPM) or tetrahedral Finite Element ...
Modeling and Estimation of Nonlinear Skin Mechanics for Animated Avatars
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
Data-driven models of human avatars have shown very accurate representations of static poses with soft-tissue deformations. However they are not yet capable of precisely representing very nonlinear deformations and highly ...
Fast and Scalable Solvers for the Fluid Pressure Equations with Separating Solid Boundary Conditions
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
In this paper, we propose and evaluate fast, scalable approaches for solving the linear complementarity problems (LCP) arising from the fluid pressure equations with separating solid boundary conditions. Specifically, we ...
Simulation of Dendritic Painting
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
We present a new system for interactive dendritic painting. Dendritic painting is characterized by the unique and intricate branching patterns that grow from the interaction of inks, solvents and medium. Painting sessions ...
A Practical Method for Animating Anisotropic Elastoplastic Materials
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
This paper introduces a simple method for simulating highly anisotropic elastoplastic material behaviors like the dissolution of fibrous phenomena (splintering wood, shredding bales of hay) and materials composed of large ...
Mixing Yarns and Triangles in Cloth Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2020)
This paper presents a method to combine triangle and yarn models in cloth simulation, and hence leverage their best features. The majority of a garment uses a triangle-based model, which reduces the overall computational ...
