Mohammad Sina Nabizadeh, Ravi Ramamoorthi, Albert Chern Solving partial differential equations (PDEs) on infinite domains has been a challenging task in physical simulations and geometry processing. We introduce a general technique to transform a PDE problem on an unbounded domain … Continue reading →

Mihail Francu, Árni Gunnar Ásgeirsson, Erleben, Kenny, Mads J. L. Rønnow The simulation of incompressible materials suffers from locking when us-ing the standard finite element method (FEM) and coarse linear tetrahedral meshes. Locking increases as the Poisson ratio?gets close to0.5and … Continue reading →

Jingwei Tang, Vinicius C. Azevedo, Guillaume Cordonnier, Barbara Solenthaler Fluid control often uses optimization of control forces that are added to a simulation at each time step, such that the final animation matches a single or multiple target density keyframes … Continue reading →

Kai Bai, Wei Li, Mathieu Desbrun, Xiaopei Liu Simulating turbulent smoke flows with fine details is computationally intensive. For iterative editing or simply faster generation, efficiently upsampling a low-resolution numerical simulation is an attractive alternative. We propose a novel learning … Continue reading →

Yun (Raymond) Fei, Qi Guo, Rundong Wu, Li Huang, Ming Gao The material point method recently demonstrated its efficacy at simulating many materials and the coupling between them on a massive scale. However, in scenarios containing debris, MPM manifests more … Continue reading →

George Sperl, Rahul Narain, Chris Wojtan Triangle mesh-based simulations are able to produce satisfying animations of knitted and woven cloth; however, they lack the rich geometric detail of yarn-level simulations. Naive texturing approaches do not consider yarn-level physics, while full … Continue reading →

Vismay Modi, Lawson Fulton, Shinjiro Sueda, Alec Jacobson, David I.W. Levin EMU is an efficient and scalable model to simulate bulk musculoskeletal motion with heterogenous materials. First, EMU requires no model reductions, or geometric coarsening, thereby producing results visually accurate … Continue reading →

Kuixin Zhu, Xiaowei He, Sheng Li, Hongan Wang, Guoping Wang Granular media is the second-most-manipulated substance on Earth, second only to water. However, simulation of granularmedia is still challenging due to the complexity of granular materials and the large number … Continue reading →

Bohan Wang, Jernej Barbič Real-time deformable object simulation is important in interactive applications such as games and virtual reality. One common approach to achieve speed is to employ model reduction, a technique whereby the equations of motion of a deformable … Continue reading →
