Modelling incompressible ideal fluids as a finite collection of vortex filaments is important in physics (super-fluidity, models for the onset of turbulence) as well as for numerical algorithms used… (More)

We show that the motion of rigid bodies under water can be realistically simulated by replacing the usual inertia tensor and scalar mass by the so-called Kirchhoff tensor. This allows us to model… (More)

Simulating fluids based on vortex filaments is highly attractive for the creation of special effects because it gives artists full control over the simulation using familiar tools like curve editors… (More)

We present a fluid solver for the real-time interactive simulation of inviscid, ideal fluid flow. The simulation is based on the evolution of discrete vortex filaments, which allow a dramatic… (More)

Fluid simulation plays a key role in various domains of science including computer graphics. While most existing work addresses fluids on bounded Euclidean domains, we consider the problem of… (More)

We describe a new approach for the purely Eulerian simulation of incompressible fluids. In it, the fluid state is represented by a C<sup>2</sup>-valued wave function evolving under the… (More)

We give an algorithm which extracts vortex filaments ("smoke rings") from a given 3D velocity field. Given a filament strength <i>h</i> > 0, an optimal number of vortex filaments, together with… (More)

We propose a novel method to extract hierarchies of vortex filaments from given three-dimensional flow velocity fields. We call these collections of filaments <i>Hierarchical Vorticity Skeletons</i>… (More)
