Clouds play an important role for creating realistic images of outdoor scenes. In order to generate realistic clouds, many methods have been developed for modeling and animating clouds. One of the most effective approaches for synthesizing realistic clouds is to … Continue reading →

Finite element simulations in computer graphics are typically based on tetrahedral or hexahedral elements, which enables simple and efficient implementations, but in turn requires complicated remeshing in case of topological changes or adaptive refinement. We propose a flexible finite element … Continue reading →

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 →
