There are two types of particle factories, Point and ZSpin. The particle panel shows a third, Oriented, but this factory does not currently work. The differences between these factories lie in the orientation and rotational abilities.

First, there are some common variables to the factories.

**Variable** | **Definition** | **Values** |

lifespanBase | Average lifespan in seconds | [0, infinity) |

lifespanSpread | Variation in lifespan | [0, infinity) |

massBase | Average particle mass | [0, infinity) |

massSpread | Variation in particle mass | [0, infinity) |

terminalVelocityBase | Average particle terminal velocity | [0, infinity) |

terminalVelocitySpread | Variation in terminal velocity | [0, infinity) |

Point particle factories generate simple particles. They have no additional parameters.

ZSpin particle factories generate particles that spin around the Z axis, the vertical axis in Panda3D. They have some additional parameters.

**Variable** | **Definition** | **Values** |

initialAngle | Starting angle in degrees | [0, 360] |

initialAngleSpread | Spread of initial angle | [0, 360] |

finalAngle | Final angle in degrees | [0, 360] |

fnalAngleSpread | Spread of final angle | [0, 360] |
