Particle system
A particle system is a computer graphics technique used to simulate fuzzy phenomena like smoke, fire, rain, or dust. Instead of modeling each element in detail, it uses many tiny particles—small points or sprites—that follow specific rules for movement, color, and life cycle. These particles collectively create realistic visual effects efficiently. Think of it as a digital cloud or spray made up of countless tiny dots that behave in ways mimicking natural phenomena, allowing artists and developers to create dynamic, visually compelling scenes without modeling every aspect individually.
