Olivier Mercier, Cynthia Beauchemin, Nils Thuerey, Theodore Kim, Derek Nowrouzezahrai We present a method to increase the apparent resolution of particlebased liquid simulations. Our method first outputs a dense, temporally coherent, regularized point set from a coarse particle-based liquid simulation. … Continue reading →

Yin Yang, Dingzeyu Li, Weiwei Xu, Yuan Tian, Changxi Zheng Model reduction has popularized itself for simulating elastic deformation for graphics applications. While these techniques enjoy orders-of-magnitude speedups at runtime simulation, the efficiency of precomputing reduced subspaces remains largely overlooked. … Continue reading →

Rahul Sheth, Wenlong Lu, Yue Yu, Ronald Fedkiw We propose a novel framework for simulating reduced deformable bodies that fully accounts for linear and angular momentum conservation even in the presence of collision, contact, articulation, and other desirable effects. This was … Continue reading →

Saket Patkar, Ning Jin, Ronald Fedkiw We present a novel sharp-crease bending element for the folding and wrinkling of surfaces and volumes. Based on a control curve specified by an artist or derived from internal stresses of a simulation, we … Continue reading →

Leonid Sigal, Moshe Mahler, Spencer Diaz, Kyna McIntosh, Elizabeth Carter, Timothy Richards, Jessica Hodgins We present a perceptual control space for simulation of cloth that works with any physical simulator, treating it as a black box. The perceptual control space … Continue reading →

Desai Chen, David I.W. Levin, Shinjiro Sueda, Wojciech Matusik Crafting the behavior of a deformable object is difficult—whether it is a biomechanically accurate character model or a new multimaterial 3D printable design. Getting it right requires constant iteration, performed either … Continue reading →

Russell Gillette, Craig Peters, Nicholas Vining, Essex Edwards, Alla Sheffer Dynamic folds and wrinkles are an important visual cue for creating believably dressed characters in virtual environments. Adding these fine details to real-time cloth visualization is challenging, as the low-quality … Continue reading →

Daniel Ram, Theodore Gast, Chenfanfu Jiang, Craig Schroeder, Alexey Stomakhin, Joseph Teran, Pirouz Kavehpour We present a new Material Point Method (MPM) for simulating viscoelastic fluids, foams and sponges. We design our discretization from the upper convected derivative terms in … Continue reading →

Gabriel Cirio, Jorge Lopez-Moreno, Miguel Otaduy Knitted cloth is made of yarns that are stitched in regular patterns, and its macroscopic behavior is dictated by the contact interactions between such yarns. We propose an efficient representation of knitted cloth at … Continue reading →

Tobias Martin, Nobuyuki Umetani, Bernd Bickel This paper introduces “OmniAD,” a novel data-driven pipeline to model and acquire the aerodynamics of three-dimensional rigid objects. Traditionally, aerodynamics are examined through elaborate wind tunnel experiments or expensive fluid dynamics computations, and are only measured … Continue reading →
