Figure 2-1. Particle basics
Figure 2-1 illustrates a scene with an emitter. The particles are created at the location of the emitter
and then travel away from that point. The emitter node is not visible. The particles are the children of the
emitter node and are visible.
To achieve a particular visual effect, you need to understand a number of concepts that will help
coordinate your code with the visual effect being implemented.
Attributes That Dictate The Appearance of a Particle System
The location of the emitter.
The rate at which the particles are emitted.
The direction or path the particles travel.
A particle's duration in the scene.
The visual attributes of a particle such as the color, shape, or transparency.
Changes to the visual appearance of a particle during its life cycle.
