Christian Hafner, Christian Schumacher, Espen Knoop, Thomas Auzinger, Bernd Bickel, Moritz Bächer We propose a novel generic shape optimization method for CAD models based on the eXtended Finite Element Method (XFEM). Our method works directly on the intersection between the … Continue reading →

Albert Peiret, Sheldon Andrews, József Kövecses, Paul G. Kry, Marek Teichmann Substructuring permits parallelization of physics simulation on multi-core CPUs. We present a new substructuring approach for solving stiff multibody systems containing both bilateral and unilateral constraints. Our approach is … Continue reading →

Tassilo Kugelstadt, Andreas Longva, Nils Thuerey, Jan Bender We propose a novel implicit density projection approach for hybrid Eulerian/Lagrangian methods like FLIP and APIC to enforce volume conservation of incompressible liquids. Our approach is able to robustly recover from highly … Continue reading →

Jan Bender, Tassilo Kugelstadt, Marcel Weiler, Dan Koschier In this paper, we present a novel method for the robust handling of static and dynamic rigid boundaries in Smoothed Particle Hydrodynamics (SPH) simulations. We build upon the ideas of the density … Continue reading →

Michael Tao, Christopher Batty, Eugene Fiume, David IW Levin Although geometry arising “in the wild” most often comes in the form of a surface representation, a plethora of geometrical and physical applications require the construction of volumetric embeddings either of … Continue reading →

Stefan Reinhardt, Tim Krake, Bernhard Eberhardt, Daniel Weiskopf We present a novel technique to correct errors introduced by the discretization of a fluid body when animating it with smoothed particle hydrodynamics (SPH). Our approach is based on the Shepard correction, … Continue reading →

Mengyuan Ding, Xuchen Han, Stephanie Wang, Theodore Gast, Joseph Teran We present a Material Point Method for visual simulation of baking breads, cookies, pancakes and similar materials that consist of dough or batter (mixtures of water flour, eggs, fat, sugar … Continue reading →

Yuanming Hu, Tzu-Mao Li, Luke Anderson, Jonathan Ragan-Kelley, Fredo Durand 3D visual computing data are often spatially sparse. To exploit such sparsity, people have developed hierarchical sparse data structures, such as multi-level sparse voxel grids, particles, and 3D hash tables. … Continue reading →

Tuanfeng Y. Wang, Tianjia Shao, Kai Fu, Niloy Mitra Authoring dynamic garment shapes for character animation on body motion is one of the fundamental steps in the CG industry. Established workflows are either time and labor consuming (i.e., manual editing … Continue reading →

David Hahn, Pol Banzet, James M. Bern, Stelian Coros This paper presents a method for optimizing visco-elastic material parameters of a finite element simulation to best approximate the dynamic motion of real-world soft objects. We compute the gradient with respect … Continue reading →
