Particle-based Viscoelastic Fluid Simulation
Philippe Beaudoin, and
Proc. Symposium on Computer Animation 2005, July 2005
We present a new particle-based method for viscoelastic fluid simulation.
We achieve realistic small-scale behavior of substances such as paint or
mud as they splash on moving objects. Incompressibility and particle
anti-clustering are enforced with a double density relaxation procedure
which updates particle positions according to two opposing pressure terms.
From this process surface tension effects emerge, enabling drop and
filament formation. Elastic and non-linear plastic effects are obtained
by adding springs with varying rest length between particles. We also
extend the technique to handle interaction between fluid and dynamic objects.
Various simulation scenarios are presented including rain drops, fountains,
clay manipulation, and floating objects. The method is robust and stable,
and can animate splashing behavior at interactive framerates.
