Jan Bender, Kenny Erleben, Jeff Trinkle, Erwin Coumans Interactive rigid body simulation is an important part of many modern computer tools. No authoring tool nor a game engine can do without. The high performance computer tools open up new possibilities … Continue reading →

Haimasree Bhattacharya, Michael Nielsen, Robert Bridson Fluid control methods often require surface velocities interpolated throughout the interior of a shape to use the velocity as a feedback force or as a boundary condition. Prior methods for interpolation in computer graphics — velocity … Continue reading →

There are some Eurographics 2012 papers on physics-based animation topics… Explicit Mesh Surfaces for Particle Based Fluids Super-Clothoids Data-Driven Estimation of Cloth Simulation Models Computational Design of Rubber Balloons STAR reports: Interactive Simulation of Rigid Body Dynamics in Computer Graphics

Jihun Yu, Chris Wojtan, Greg Turk, Chee Yap We introduce the idea of using an explicit triangle mesh to track the air/fluid interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial surface mesh is created, this mesh is … Continue reading →

Landon Boyd, Robert Bridson Physically-based liquid animations often ignore the influence of air, giving up interesting behaviour. We present a new method which treats both air and liquid as incompressible, more accurately reproducing the reality observed at scales relevant to computer … Continue reading →

Efficient Computational Methods for Phyically-Based Simulation – Bernhard Thomaszewski, Tuebingen Practical Methods for Simulation of Compressible Flow and Structure Interactions – Nipun Kwatra, Stanford Coupled Simulation of Deformable Solids, Rigid Bodies, and Fluids – Craig Schroeder, Stanford Strand-Based Musculotendon Simulation … Continue reading →

Gilles Daviet, Florence Bertails-Descoubes, Laurence Boissieux Dry friction between hair fibers plays a major role in the collective hair dynamic behavior as it accounts for typical nonsmooth features such as stick-slip instabilities. However, due the challenges posed by the modeling … Continue reading →

Barbara Solenthaler, Peter Bucher, Nuttapong Chentanez, Matthias Muller, Markus Gross We present an efficient method that uses particles to solve the 2D shallow water equations. These equations describe the dynamics of a body of water represented by a height field. … Continue reading →

The program for VRIPHYS 2011 is up, which includes the following physics-related papers: Simulating inextensible cloth using locking-free triangle meshes Adding physics to animated characters using oriented particles Focused ultrasound – Efficient GPU simulation methods for therapy planning Time adaptive … Continue reading →

Matthias Muller, Nuttapong Chentanez We present a method to enhance the realism of animated characters by adding physically based secondary motion to deformable parts such as cloth, skin or hair. To this end, we extend the oriented particles approach to incorporate … Continue reading →
