The event is the basic unit of organization in a Particle Flow particle diagram. There are two types of events: global and local. A birth event is a specialized type of local event.
1. Global event
2. Birth event
3. Local event
Each event contains one or more actions, which can affect particle behavior or appearance. You can use tests to send particles to other events if the particles meet certain qualifications. A single chain of linked events as shown in Particle View is known as a flow.
