Particle systems are used to create many different special effects like fire, rain, and smoke. They are used in virtually all video games, as well as in a lot of movie special effects. But what is a particle? In essence, a particle is something represented by a point in space, a dot. In practice, particles are often useful for simulating effects that consist of many small objects. Now “small” really depends on the context. If you are planning to simulate a galaxy, you will need to treat stars, or even clusters of stars as particles. If you are simulating rain, your particles will be individual raindrops.
