Introduction to Particle System

Another useful technology, many games will benefit from the use of particle systems, which are small, smooth, use transparent rendering in the scene to create texture triangles that can add a large number of atmosphere effects to your game world.

The particle system is added to a game, just like any other object, but has the following features:

1) they often use a technology called announcement board to determine their direction so that they can face the camera directly.

2) They usually close the write depth buffer so that they do not close the other one.

3) They are often rendered to every scene update. Because they do not update the depth buffer, the rendering Order prevents objects after them from appearing before them.

4) they are almost always added to a group rather than separately.
