3D node
Particle System
Spawns and simulates a stream of moving points with adjustable emit rate, lifetime, initial speed, and turbulence — sparks, dust, snow, or drifting motes, all reacting in real time.
What it does
Particle System is a 3D node: it builds, changes or lights geometry that Render 3D turns into a picture. It has no input and gives 3D shape out, so it starts a chain.
Try it
Trigger a burst of particles on every kick drum for a fireworks-on-the-beat effect.

Controls
Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
