**Points** | P | Set of points on surface to tween between | Point |

**Surface** | S | Surface to tween point on | Surface |

**Factor** | F | Tween factor (0.0 = Point at P start, 1.0 = Point at P end), unless Normalized is False | Number |

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

**Equalized** | E | If True, tween distribution is evaluated along the tween path without considering the locations of the input point set | Boolean |

**Weighted** | W | If True, tween distribution is weighted by the input point set and the tween path curvature | 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 |

**Degree** | D | Curvature degree of the tween path, degree should be a positive odd number | Integer |

**Interpolation Type** | I | Determines how the tween path is interpolated
0 = Linear
1 = Chord
2 = Square Root
3 = Uniform | Integer |
