Particle Effects

A particle system generates, animates, and renders thousands of individual elements (particles) according to defined rules. An emitter defines where particles are born (a point, line, or area). Birth rate controls how many particles appear per frame. Each particle has properties: size, color, opacity, velocity, and lifespan. Physics forces (gravity, wind, turbulence) affect particle movement. Over its lifespan, each particle can change size (grow and shrink), color (white to orange to dark gray for fire), and opacity (fade in and out). The collective behavior of thousands of individually simple particles creates complex, organic-looking effects: rain, snow, dust, sparks, fire embers, smoke, and magic particles.
