A particle system is a computer graphics technique used to simulate and render small, dynamic elements, known as particles, in visual effects, animations, and simulations. These particles can represent various phenomena, such as raindrops, fire, smoke, or sparks. The behavior and appearance of each particle are defined by parameters like size, color, velocity, and lifespan.
Envision a scene where a fire effect is created in a video game – a particle system generates individual particles to mimic the appearance of flames, each particle contributing to the overall dynamic and realistic quality of the fire. Particle systems are versatile tools employed in game development, animation, and simulations, allowing for the creation of visually compelling and interactive effects.
