Particle systems

Definition

Particle systems are a technique in computer graphics used to simulate and render complex phenomena, such as smoke, fire, rain, and explosions, by managing a large number of individual particles that behave according to simple rules. This approach allows for the creation of intricate visual effects that enhance realism and artistic expression in both 2D and 3D environments, enabling developers to craft immersive experiences in their games.
