An emitter is what's creating the particles. Emitters are usually not visible, but they can have

|
a shape. That shape controls where and how particles are spawned, for example whether they should fill

|
|
a room like dust or shoot away from a single point like a fountain. Going back to the fire example,
|
|
|
an emitter would be the heat at the center of the fire that creates the embers and the flames.
