Jonathan Panuelos, Ryan Goldade, Eitan Grinspun, David Levin, Christopher Batty Standard liquid simulators apply operator splitting to independently solve for pressure and viscous stresses, a decoupling that induces incorrect free surface boundary conditions. Such methods are unable to simulate fluid … Continue reading →

Tianyu Wang, Jiong Chen, Dongping Li, Xiaowei Liu, Huamin Wang, Kun Zhou Step-and-project is a popular method to simulate non-penetrating deformable bodies in physically-based animation. The strategy is to first integrate the system in time without considering contacts and then … Continue reading →

Zachary Ferguson, Pranav Jain, Denis Zorin, Teseo Schneider, Daniele Panozzo High-order bases provide major advantages over linear ones in terms of efficiency, as they provide (for the same physical model) higher accuracy for the same running time, and reliability, as … Continue reading →

Zachary Ferguson, Teseo Schneider, Danny M. Kaufman† Daniele Panozzo† (†Joint last authors) We propose a fully coupled, adaptive meshing algorithm for contacting elastodynamics where remeshing steps are tightly integrated, implicitly, within the time-step solve. Our algorithm refines and coarsens the … Continue reading →

Two-Way Coupling of Skinning Transformations and Position Based Dynamics Physical Cyclic Animations Micropolar Elasticity in Physically-Based Animation A Linear and Angular Momentum Conserving Hybrid Particle/Grid Iteration for Volumetric Elastic Contact Towards Realtime: A Hybrid Physics-based Method for Hair Animation on … Continue reading →

Yunuo Chen, Tianyi Xie, Cem Yuksel, Danny Kaufman,Yin Yang, Chenfanfu Jiang, Minchen Li We present a novel mesh-based method for simulating the intricate dynamics of (potentially multi-layered) continuum thick shells. In order to accurately represent the constitutive behavior of structural … Continue reading →

Wei Li, Mathieu Desbrun Real-life flows exhibit complex and visually appealing behaviors such as bubbling, splashing, glugging and wetting that simulation techniques in graphics have attempted to capture for years. While early approaches were not capable of reproducing multiphase flow … Continue reading →

Chaoyang Lyu, Kai Bai, Yiheng Wu, Mathieu Desbrun, Changxi Zheng, Xiaopei Liu Virtual wind tunnel testing is a key ingredient in the engineering design process for the automotive and aeronautical industries as well as for urban planning: through visualization and … Continue reading →

Kangrui Xue, Ryan M. Aronson, Jui-Hsien Wang, Timothy R. Langlois, Doug L. James We introduce a practical framework for synthesizing bubble-based water sounds that captures the rich inter-bubble coupling effects responsible for low-frequency acoustic emissions from bubble clouds. We propose … Continue reading →

Simon Duenser, Bernhard Thomaszewski, Roi Poranne, Stelian Coros Many flexible structures are characterized by a small number of compliant modes, i.e., large deformation paths that can be traversed with little mechanical effort, whereas resistance to other deformations is much stiffer. … Continue reading →
