Egor Larionov, Andreas Longva, Uri M. Ascher, Jan Bender, Dinesh K. Pai Dynamics simulation with frictional contacts is important for a wide range of applications, from cloth simulation to object manipulation. Recent methods using smoothed lagged friction forces have enabled … Continue reading →

Yinwei Du, Yue Li, Stelian Coros, Bernhard Thomaszewski, Modeling contact between deformable solids is a fundamental problem in computer animation, mechanical design, and robotics. Existing methods based on C0-discretizations—piece-wise linear or polynomial surfaces—suffer from discontinuities and irregularities in tangential contact … Continue reading →

Alexandre Mercier-Aubin, Paul G. Kry We present a novel multi-layer method for extended position-based dynamics that exploits a sequence of reduced models consisting of rigid and elastic parts to speed up convergence. Taking inspiration from concepts like adaptive rigidification and … Continue reading →

Lukas Westhofen, José Antonio Fernández-Fernández, Stefan Rhys Jeske, Jan Bender We present a strongly coupled method for the robust simulation of linear magnetic rigid bodies. Our approach describes the magnetic effects as part of an incremental potential function. This potential … Continue reading →

Quoc-Minh Ton-That, Paul G. Kry, Sheldon Andrews Traditional mesh-based methods for cutting deformable bodies rely on modifying the simulation mesh by deleting, duplicating, deforming or subdividing its elements. Unfortunately, such topological changes eventually lead to instability, reduced accuracy, or computational … Continue reading →

Yalan Zhang, Long Shen, Yanrui Xu, and Xiaokun Wang, Chao Yao, Jiri Kosinka, Alexandru Telea, Steffen Frey, Xiaojuan Ban We propose a method for simulating viscoelastic non-Newtonian fluids within a multiphase framework. For this, we use mixture models to handle component transport … Continue reading →

Fabian Löschner, José Antonio Fernández-Fernández, Stefan Rhys Jeske, Jan Bender Continuum-based shell models are an established approach for the simulation of thin deformables in computer graphics. However, existing research in physically-based animation is mostly focused on shear-rigid Kirchhoff-Love shells. In … Continue reading →
