Understanding Particle System Concepts

Particle systems are a technique used in computer graphics to simulate a variety of phenomena, such as fire, smoke, rain, and explosions. In a game engine, particle systems are used to add realism and visual interest to scenes. The three main functions of particle systems are emission, simulation, and rendering.

Emission is the process of creating and releasing particles from a specific location or object. This is controlled through properties such as emission rate, velocity, and direction. Emission can also be triggered by events, such as collisions or user input.

Simulation refers to the movement and behavior of the particles over time. This can include properties such as gravity, wind, and turbulence, which can be used to create realistic movement patterns. Particles can also be affected by other forces, such as collisions and user-defined behaviors.

Rendering is the process of displaying the particles on the screen. This can be done...
