Simulating colliding particles in Java using Parsimony

This paper describes an implementation of a colliding particle simulation in Java using Parsimony (Preiss, 1998). The simulation predicts the movements and interactions of particles in a bounded, 3-dimensional enclosure. Particle events are displayed graphically using a visualization tool based on Java3D. The use of Parsimony allows the simulation to be easily distributed across the Internet. The simulation may be executed using a choice of conservative and optimistic discrete-event simulation techniques. This paper focuses on the steps involved in developing a complex, graphical simulation in Java using Parsimony.
