Huancheng Lin, Floyd M. Chitalu, Taku Komura Isotropic As-Rigid-As-Possible (ARAP) energy has been popular for shape editing, mesh parametrisation and soft-body simulation for almost two decades. However, a formulation using Cauchy-Green (CG) invariants has always been unclear, due to a … Continue reading →

Julian Panetta, Haleh Mohammadian, Emiliano Luci, Vahid Babaei Objects with different shapes can dissolve in significantly different ways inside a solution. Predicting different shapes’ dissolution dynamics is an important problem especially in pharmaceutics. More important and challenging, however, is controlling … Continue reading →

Mianlun Zheng*, Bohan Wang*, Jingtao Huang, Jernej Barbič (*joint first authors) Precision modeling of the hand internal musculoskeletal anatomy has been largely limited to individual poses, and has not been connected into continuous volumetric motion of the hand anatomy actuating … Continue reading →

Jinyuan Liu, Mengdi Wang, Fan Feng, Annie Tang, Qiqin Le, Bo Zhu   We propose a novel solid-fluid coupling method to capture the subtle hydrophobic and hydrophilic interactions between liquid, solid, and air at their multi-phase junctions. The key component … Continue reading →

Damien Rioux-Lavoie*, Ryusuke Sugimoto*, Tümay Özdemir, Naoharu H. Shimada, Christopher Batty, Derek Nowrouzezahrai, Toshiya Hachisuka (*joint first authors) We present a novel Monte Carlo-based fluid simulation approach capable of pointwise and stochastic estimation of fluid motion. Drawing on the Feynman-Kac … Continue reading →

Silvia Sellán, Jack Luong, Leticia Mattos Da Silva, Aravind Ramakrishnan, Yuchuan Yang, Alec Jacobson Drawing a direct analogy with the well-studied vibration or elastic modes, we introduce an object’s fracture modes, which constitute its preferred or most natural ways of … Continue reading →

Ying Wang, Jasper Verheul, Sang-Hoon Yeo, Nima Khademi Kalantari, Shinjiro Sueda We propose a simple and practical approach for incorporating the effects of muscle inertia, which has been ignored by previous musculoskeletal simulators in both graphics and biomechanics. We approximate … Continue reading →

Differentiable Simulation of Inertial Musculotendons Simulation of Hand Anatomy Using Medical Imaging Shape from Release: Inverse Design and Fabrication of Controlled Release Structures Isotropic ARAP energy using Cauchy-Green invariants Breaking Good: Fracture Modes for Realtime Destruction Fast Stabilization of Inducible … Continue reading →

Pengbin Tang, Stelian Coros, Bernhard Thomaszewski Strain limiting is a widely used approach for simulating biphasic materials such as woven textiles and biological tissue that exhibit a soft elastic regime followed by a hard deformation limit. However, existing methods are … Continue reading →

Ryusuke Sugimoto, Christopher Batty, Toshiya Hachisuka We propose a novel surface-only method for simulating dynamic deformables without the need for volumetric meshing or volumetric integral evaluations. While based upon a boundary element method (BEM) for linear elastodynamics, our method goes … Continue reading →
