Particle System Brief
A particle system is a graphics technique used to simulate complex physical effects. It is a collection of small pictures that, when viewed together, form a more blurred object, such as: flames, smoke, weather or fireworks.
Particle system effects are very common in movies and games. For example: for the effect of a plane crash, the particle system can be used to simulate the scene of the plane explosion, and then another particle system can be used to simulate the smoke trail when the plane crashes.
