Magic Fluid Control
N. Thuerey, R. Keiser, M. Pauly, U. Ruede
The movie consists of three clips to demonstrate the possibilities
of controlled water simulations:
1. A magician pulls out water from a basin which forms a teapot by
moving his hand upwards from the basin.
2. Water flows magically upwards a stair where it forms a human figure.
This is achieved by using control particles from a reversed water
simulation and from an invisible model.
3. The magician moves a duck out of water from one basin to another and
vice versa. Finally, he pulls out two ducks from both basins which end
up in a short "fight".

Nils Thuerey is a PhD student at the chair for system simulation
of the University Erlangen-Nuremberg, Germany. He is working on algorithms
for free surface fluid simulations.
Richard Keiser is a research associate and PhD student at the computer
science department of ETH Zurich, Switzerland. He specializes in physics
based animations using particles and deformable point-based surface
modeling.
Mark Pauly is professor at the computer science department of ETH Zurich and
focuses on efficient representations and algorithms for dynamic 3D shapes.
Ulrich Ruede is head of the system simulation chair of the University
Erlangen-Nuremberg. He deals with the modelling, efficient simulation
and optimization of complex systems in science and engineering.
The animation has been created in the context of the authors' work
on controlled fluid simulation. The water is simulated using the
Lattice-boltzman method. It is controlled using particles which define
local force fields and are generated automatically from either a
physical simulation or a sequence of target shapes. At the same time,
as much as possible of the natural fluid motion is preserved. The framework
has been integrated into the open source software Blender, which was used
to animate and render the shown sequences.
