Particle Systems

  • Murilo G. Coutinho


Particles are among the simplest and most versatile objects used in dynamic simulations. The fact that their mass is concentrated on a point (i.e., center of mass) considerably simplifies the dynamic equations governing their motion. All interaction forces among themselves and with other objects in the simulation are applied to the points representing each particle, and the rotational motion of a point is undefined, and therefore ignored. The reduced complexity in the dynamic equations allows for an increased number of particles being simulated without significantly imparing operation of the simulation engine. These simplifications make particle systems an extremely attractive option to simulate systems requiring a large number of objects that can be approximated as a collection of point-mass objects. Examples of such systems range from molecules, to smoke, fire, clouds, liquids, and even cloth.
