History of Particle System
The origin of the particle system can be traced back to the movie industry:
“A particle system is a collection of many many minute particles that together represent a fuzzy object. Over a period of time, particles are generated into a system, move and change from within the system, and die from the system.”
— William Reeves, "Particle Systems—A Technique for Modeling a Class of Fuzzy Objects," ACM Transactions on Graphics 2:2 (April 1983), 92.
Particle
A particle in game is usually a sprite or 3D model, with the following attributes:
- Position
- Velocity
- Size
- Color
- Lifetime

Particle Emitter
Particle Emitter is used to define the particles simulation
- Specify the spawn rules
- Specify simulation logic
- Describe how to render particles
Particle System A particle system is a collection of individual emitters
Particle system is crucial to any 3D effects.
The spawn position (single position spawn, spawn based on area, spawn based on mesh), and spawn modes (continuous, burst) will affect the how it looks in the end.
Simulation controls how the particles change over time.
