Curly Hair Simulation using Curly Finite Elements
Xinming Pei, Zhendong Wang, Lei Lan +3
Realistic simulation of curly hair is challenging due to the tight coupling between macroscopic strand deformation and high-frequency geometric details such as waves and helices. I…
Distributed Affine Body Dynamics with Adaptive Consensus
Jiafeng Liu, Wenhui Zhou, Xinming Pei +5
Affine Body Dynamics (ABD) within the Incremental Potential Contact (IPC) framework provides accurate simulation of extremely stiff solids exhibiting near-rigid behavior, with stri…
ElastoGen: 4D Generative Elastodynamics
Yutao Feng, Yintong Shang, Xiang Feng +7
We present ElastoGen, a knowledge-driven AI model that generates physically accurate 4D elastodynamics. Unlike deep models that learn from video- or image-based observations, Elast…
JGS2: Near Second-order Converging Jacobi/Gauss-Seidel for GPU Elastodynamics
Lei Lan, Zixuan Lu, Chun Yuan +5
In parallel simulation, convergence and parallelism are often seen as inherently conflicting objectives. Improved parallelism typically entails lighter local computation and weaker…
