S. Auer, C. B. MacDonald, M. Treib, J. Schneider, R. Westermann The Closest Point Method (CPM) is a method for numerically solving partial differential equations (PDEs) on arbitrary surfaces, independent of the existence of a surface parametrization. The CPM uses … Continue reading →

Jan Bender, Matthias Müller, Miguel A. Otaduy and Matthias Teschner The dynamic simulation of solids has a long history in computer graphics. The classical methods in this field are based on the use of forces or impulses to simulate joints … Continue reading →

Theodore Kim, Jerry Tessendorf, Nils Thuerey We propose a method of increasing the apparent spatial resolution of an existing liquid simulation. Previous approaches to this “up-resing” problem have focused on increasing the turbulence of the underlying velocity field. Motivated by … Continue reading →

The Oscars for Scientific and Technical Achievement were announced recently, and among them are a pair of tools for physics-based animation: To Theodore Kim, Nils Thuerey, Markus Gross and Doug James for the invention, publication and dissemination of Wavelet Turbulence software. This technique allowed for fast, … Continue reading →

Hayley Iben, Mark Meyer, Lena Petrovic, Olivier Soares, John Anderson, Andrew Witkin We present a novel method for stably simulating stylized curly hair that addresses artistic needs and performance demands, both found in the production of feature films. To satisfy … Continue reading →

Pascal Clausen, Martin Wicke, Jonathan Shewchuk, James O’Brien This paper describes a Lagrangian finite element method that simulates the behavior of liquids and solids in a unified framework. Local mesh improvement operations maintain a high-quality tetrahedral discretization even as the … Continue reading →

Jonathan R. Bronson, Joshua A. Levine, Ross T. Whitaker We introduce a new algorithm for generating tetrahedral meshes that conform to physical boundaries in volumetric domains consisting of multiple materials. The proposed method allows for an arbitrary number of materials, … Continue reading →

Fun Shing Sin, Daniel Schroeder, Jernej Barbic This practice and experience paper describes a robust C++ implementation of several non-linear solid three-dimensional deformable object strategies commonly employed in computer graphics, named the Vega finite element method (FEM) simulation library. Deformable … Continue reading →

Taylor Patterson, Nathan Mitchell, Eftychios Sifakis Lattice deformers are a popular option for modeling the behavior of elastic bodies as they avoid the need for conforming mesh generation, and their regular structure offers significant opportunities for performance optimizations. Our work expands the … Continue reading →
