Ke-Sen’s list of SIGGRAPH Asia 2009 papers is starting to fill out. Here’s some of the more physics-related ones: Stretching and Wiggling Liquids Skipping Steps in Deformable Simulation with Online Model Reduction Synthetic Turbulence using Artificial Boundary Layers Motion Field Texture Synthesis

Sony has released an open source project that underpins their fluid simulation and volume rendering tools, called Field3D.

The list of papers from the 2009 Symposium on Computer Animation have been up for a while at Ke-Sen Huang’s page. Here’s the subset that fall most directly under physics-based animation: A Point-based Method for Animating Elastoplastic Solids Statistical Simulation of Rigid Bodies Anisotropic Friction for Deformable Surfaces and Solids Energy Stability and Fracture for […]

We propose a novel approach to guiding of Eulerian-based smoke animations through coupling of simulations at different grid resolutions. Specifically we present a variational formulation that allows smoke animations to adopt the low-frequency features from a lower resolution simulation (or non-physical synthesis), while simultaneously developing higher frequencies. The overall motivation for this work is to […]

Surface tracking is an important problem with applications in many research fields. Among the most famous examples in computer graphics is the simulation and rendering of liquids with free surfaces. A surface that is advected by a general velocity field constantly changes its topology. This is the main reason why moving surfaces are typically defined […]

We present a practical approach to isotropic tetrahedral meshing of 3D domains bounded by piecewise smooth surfaces. Building upon recent theoretical and practical advances, our algorithm interleaves Delaunay refinement and mesh optimization to generate quality meshes that satisfy a set of user-defined criteria. This interleaving is shown to be more conservative in number of Steiner […]

We develop a method for reliable simulation of elastica in complex contact scenarios. Our focus is on firmly establishing three parameter-independent guarantees: that simulations of well-posed problems (a) have no interpenetrations, (b) obey causality, momentum- and energy-conservation laws, and (c) complete in finite time. We achieve these guarantees through a novel synthesis of asynchronous variational […]

This paper introduces a data-driven representation and modeling technique for simulating non-linear heterogeneous soft tissue. It simplifies the construction of convincing deformable models by avoiding complex selection and tuning of physical material parameters, yet retaining the richness of non-linear heterogeneous behavior. We acquire a set of example deformations of a real object, and represent each […]

It’s that time of year again… Here’s the link to Ke-Sen’s more complete list. Physics-related papers: Energy-Preserving Integrators for Fluid Animation Interactive Simulation of Surgical Needle Insertion and Steering Modular Bases for Fluid Dynamics Numerical Coarsening of Inhomogeneous Elastic Materials Capture and Modeling of Non-Linear Heterogeneous Soft Tissue Interleaving Delaunay Refinement and Optimization for Practical […]

We present a method for simulating highly detailed cutting and fracturing of thin shells using low-resolution simulation meshes. Instead of refining or remeshing the underlying simulation domain to resolve complex cut paths, we adapt the extended finite element method (XFEM) and enrich our approximation by custom designed basis functions, while keeping the simulation mesh unchanged.
