Nobuyuki Umetani, Ryan Schmidt, Jos Stam We present a novel method to simulate complex bending and twisting of elastic rods. Elastic rods are commonly simulated using force based methods, such as the finite element method. These methods are accurate, but … Continue reading →

Yijing Li, Jernej Barbič Isotropic Finite Element Method (FEM) deformable object simulations are widely used in computer graphics. Several applications (wood, plants, muscles) require modeling the directional dependence of the material elastic properties in three orthogonal directions. We investigate orthotropic … Continue reading →

Dan Koschier, Sebastian Lipponer, Jan Bender We present a method for the adaptive simulation of brittle fracture of solid objects based on a novel reversible tetrahedral mesh refinement scheme. The refinement scheme preserves the quality of the input mesh to … Continue reading →

Todd Keeler, Robert Bridson We tackle deep water simulation in a scalable way, solving 3D irrotational flow using only variables stored in a mesh of the surface of the water, in time proportional to the rendered mesh. The heart of our method … Continue reading →

Woojong Koh, Rahul Narain, James F. O’Brien This paper describes a method for view-dependent cloth simulation using dynamically adaptive mesh refinement and coarsening. Given a prescribed camera motion, the method adjusts the criteria controlling refinement to account for visibility and apparent … Continue reading →

James Gregson, Ivo Irkhe, Nils Thuerey, Wolfgang Heidrich We explore the connection between fluid capture, simulation and proximal methods, a class of algorithms commonly used for inverse problems in image processing and computer vision. Our key finding is that the … Continue reading →

Bo Reng, Chenfeng Li, Xiao Yan, Ming C. Lin, Javier Bonet, Shi-Min Hu This paper presents a versatile and robust SPH simulation approach for multiple-fluid flows. The spatial distribution of different phases or components is modeled using the volume fraction … Continue reading →

Sofien Bouaziz, Sebastian Martin, Tiantian Liu, Ladislav Kavan, Mark Pauly We present a new method for implicit time integration of physical systems. Our approach builds a bridge between nodal Finite Element methods and Position Based Dynamics, leading to a simple, efficient, robust, yet … Continue reading →

Matthias Mueller, Nuttapong Chentanez, Tae-Yong Kim, Miles Macklin We propose a new set of constraints within the Position Based Dynamics (PBD) framework that allow the control of strain in directions that are independent of the edge directions of the simulation mesh. … Continue reading →
