An interactive animation method for viscoelastic materials builds on Rouse's spring-bead model. Particles are connected one dimensionally by spring forces to represent single polymer chains. The method approximates the collision's force between particles through the particle density's gradient. This model lets the viscoelasticity be changed dynamically by severing the interconnection of polymer chains.
