We present a new shape-matching deformation model that allows for efficient handling of topological changes and dynamic adaptive selection of levels of detail. Similar to the recently presented Fast Lattice Shape Matching (FLSM), we compute the position of simulation nodes … Continue reading →

The 2008 edition of the annual unofficial list of SIGGRAPH papers is up. It’s looking like a big year for physics – just over 14% so far… Fast Viscoelastic Behavior with Thin Features Backward Steps in Rigid Body Simulations Bubbles … Continue reading →

The list of papers accepted to the 2008 Symposium on Computer Animation is up here. The physics-oriented subset of those papers: Evolving Sub-Grid Turbulence for Smoke Animation Low Viscosity Flow Simulations for Animation Visual Simulation of Shockwaves Fast Adaptive Shape … Continue reading →

We present a combination of techniques to simulate turbulent fluid flows in 3D. Flow in a complex domain is modeled using a regular rectilinear grid with a finite-difference solution to the incompressible Navier-Stokes equations. We propose the use of the … Continue reading →

To simulate multiple fluids realistically many important interaction effects have to be captured accurately. Smoothed Particle Hydrodynamics (SPH) has shown to be a simple, yet flexible method to cope with many fluid simulation problems in a robust way. Unfortunately, the … Continue reading →

We propose a framework for the full two-way coupling of rigid and deformable bodies, which is achieved with both a unified time integration scheme as well as individual two-way coupled algorithms at each point of that scheme. As our algorithm … Continue reading →

We propose a novel solid/fluid coupling method that treats the coupled system in a fully implicit manner making it stable for arbitrary time steps, large density ratios, etc. In contrast to previous work in computer graphics, we derive our method … Continue reading →

We introduce a simple turbulence model for smoke animation, qualitatively capturing the transport, diffusion, and spectral cascade of turbulent energy unresolved on a typical simulation grid. We track the mean kinetic energy per octave of turbulence in each grid cell, … Continue reading →

We present a new image-based method to process contacts between objects bounded by triangular surfaces. Unlike previous methods, it relies on image-based volume minimization, which eliminates complex geometrical computations and robustly handles deep intersections.  The surfaces are rasterized in three … Continue reading →

In this paper we simulate high resolution cloth consisting of up to 2 million triangles which allows us to achieve highly detailed folds and wrinkles. Since the level of detail is also influenced by object collision and self collision, we … Continue reading →
