**Plane** | Pl | Plane for the vortex to operate on. The origin of the plane is the singularity point of the vortex | Plane |

**Exponent** | h | Distance from field where integration will halt. 0 to run until integration is complete | Number |

**Factor** | k | Scalar multiple of the gravity force (positive for attraction, negative for repulsion) | Number |

**Rotational Factor** | a | Scalar multiple of the effect the spiral causes on the vector field | Number |

**Exact** | e | Use exact geodesic distances to calculate spiral path when on a surface, otherwise use a fast approximation | Boolean |

**Funnel** | F | True if you want a funnel instead of a vortex. A funnel will attract on one side and shoot out the other | Boolean |

**Reverse** | R | True if you want to reverse the spiral when constrained to a surface | Boolean |
