**Domain²s** | I² | Set of domain²s to tween through | Domain² |

**Factor U** | uF | Tween factor {u} (0.0 = Domain² {u} at start, 1.0 = Domain² {u} at end), unless Normalized is False | Number |

**Factor V** | vF | Tween factor {v} (0.0 = Domain² {v} at start, 1.0 = Domain² {v} at end), unless Normalized is False | Number |

**Normalized** | N | If False, the rules for factor are (0.0 = Domain² {u}{v} at index 0, Index number of last domain² {u}{v} = Domain² {u}{v} at last index)
The tween factor range from one domain² {u}{v} to the next domain² {u}{v} in the list is:
Index number of a domain² {u}{v} = the domain² {u}{v} at that index, Index number of the next domain² {u}{v} = the next domain² {u}{v} in the list, factors between the domain² {u}{v} index numbers will be the corresponding tweens.
For instance:
A tween factor of 2.5 will result in a tween domain² {u}{v} halfway between the domain² {u}{v} at index 2 and the domain² {u}{v} at index 3. | Boolean |

**Equalized** | E | If True, tween distribution is evaluated between the extremes of the input domain² set without considering the locations of the input domain² set | Boolean |

**Loopback** | L | If True, allow the tween path to continue from the end back to the start as a closed loop
(if Normalized is False, increase the tween factor range maximum by 1) | Boolean |
