Honglin Chen, Hseuh-Ti Derek Liu, Alec Jacobson, David I. W. Levin, Changxi Zheng We introduce a novel adaptive eigenvalue filtering strategy to stabilize and accelerate the optimization of Neo-Hookean energy and its variants under the Projected Newton framework. For the … Continue reading →

Aoran Lyu, Shixian Zhao, Chuhua Xian, Zhihao Cen, Hongmin Cai, Guoxin Fang Reduced-order simulation is an emerging method for accelerating physical simulations with high DOFs, and recently developed neural-network-based methods with nonlinear subspaces have been proven effective in diverse applications … Continue reading →

Ty Trusty, Yun (Raymond) Fei, David I.W. Levin, Danny M. Kaufman We construct a subspace simulator that adaptively balances solution improvement against system size. The core components of our simulator are an adaptive subspace oracle, model, and parallel time-step solver … Continue reading →

Xingyu Ni*, Xuwen Chen* (joint 1st authors), Cheng Yu, Bin Wang, Baoquan Chen In this study, we present the bicubic Hermite element method (BHEM), a new computational framework devised for the elastodynamic simulation of thin-shell structures. The BHEM is constructed … Continue reading →

Xuwen Chen, Cheng Yu, Xingyu Ni, Mengyu Chu, Bin Wang, Baoquan Chen Continuous collision detection (CCD) between parametric surfaces is typically formulated as a five-dimensional constrained optimization problem. In the field of CAD and computer graphics, common approaches to solving … Continue reading →

Peng Fang, Wei Wang, Ruofeng Tong, Hailong Li, Min Tang Computing maximum/minimum distances between 3D meshes is crucial for various applications, i.e., robotics, CAD, VR/AR, etc. In this work, we introduce a highly parallel algorithm (gDist) optimized for Graphics Processing … Continue reading →

Antoine Chan-Lock, Miguel A. Otaduy This paper introduces a new formulation for material homogenization of thin-shell microstructures. It addresses important challenges that limit the quality of previous approaches: methods that fit the energy response neglect visual impact, methods that fit … Continue reading →

Liliane-Joy Yana Dandy, Michele Vidulis, Yingying Ren, Mark Pauly We study ensembles of elastic rods that are tensioned by a small set of inextensible cables. The cables induce forces that deform the initially straight, but flexible rods into 3D space … Continue reading →

Zizhou Huang, Daniele Panozzo, Denis Zorin Mechanical shock is a common occurrence in various settings, there are two different scenarios for shock protection: catastrophic protection (e.g. car collisions and falls) and routine protection (e.g. shoe soles and mattresses). The former … Continue reading →

Qiqin Le, Jiamu Bu, Yanke Qu, Bo Zhu, Tao Du We develop a computational pipeline to facilitate the biomimetic design of winged seeds. Our approach leverages 3D scans of natural winged seeds to construct a bio-inspired design space by interpolating … Continue reading →
