Juntian Zheng, Zhaofeng Luo, Minchen Li We introduce a barrier-free optimization framework for non-penetration elastodynamic simulation that matches the robustness of Incremental Potential Contact (IPC) while overcoming its two primary efficiency bottlenecks: (1) reliance on logarithmic barrier functions to enforce … Continue reading →

Alvin Shi, Florence Bertails-Descoubes, A.M. Darke, Theodore Kim Due to its highly curved geometry, tightly coiled hair is challenging to model and edit using standard position-based tools. In this work we propose using material curvatures and twists to analyze and … Continue reading →

Runze Zhang, Bo Ren The intricate motion arising from fluid–boundary interactions is visually compelling, yet notoriously difficult and computationally expensive to simulate in the presence of complex boundaries. Accurately resolving boundary geometry requires body-fitted grids constructed via cut-cell methods, which … Continue reading →

Ruolan Li, Yanrui Xu, Yalan Zhang, and Jiri Kosinka, Alexandru C. Telea, Jian Chang, Jian Jun Zhang, Xiaojuan Ban, Xiaokun Wang Simulating the interactions between fluids and porous media has attracted significant attention in computer graphics. A key challenge in … Continue reading →

Helge Wrede, Anton R. Wagner, Sarker Miraz Mahfuz, Wojtek Pałubicki, Dominik L. Michels, Sören Pirk We present a novel combustion simulation framework to model fire phenomena across solids, liquids, and gases. Our approach extends traditional fluid solvers by incorporating multi-species … Continue reading →

Timna Böttcher, Lukas Westhofen, Stefan Rhys Jeske, Jan Bender We present a novel implicit porous flow solver using SPH, which maintains fluid incompressibility and is able to model a wide range of scenarios, driven by strongly coupled solid-fluid interaction forces. … Continue reading →

Haoxiang Wang, Kui Wu, Hui Qiao, Mattieu Desbrun, Wei Li Kinetic multiphase flow solvers have recently demonstrated exquisitely complex and turbulent fluid phenomena involving splashing and bubbling. However, they require full simulation of both the liquid phase and the air … Continue reading →

Zhiqi Li, Jinjin He, Barnabás Börcsök, Taiyuan Zhang, Duowen Chen, Tao Du, Ming C. Lin, Greg Turk, Bo Zhu This paper presents a novel adjoint solver for differentiable fluid simulation based on bidirectional flow maps. Our key observation is that … Continue reading →

Xiao Sean Zhan, Evan Thompson, Clément Jambon, Kenney Ng, Mina Konaković Luković Generative models have recently demonstrated impressive capabilities in producing high-quality 3D shapes from a variety of user inputs (e.g., text or images). However, generated objects often lack physical … Continue reading →

Yura Hwang, Jenny Han Lin, Jerry Hsu, Benjamin Mastripolito, James McCann, Cem Yuksel Lightweight, mesh-level models of knit fabric behavior are useful for both interactive pattern editing and initialization of yarn-level simulations. However, existing mesh-level simulation methods abstract knitting as … Continue reading →
