|Surfaces||S||Set of surfaces to tween through||Surface|
|Factor||F||Tween factor (0.0 = Surface at S start, 1.0 = Surface at S end), unless Normalized is False||Number|
|Normalized||N||If False, the rules for factor are (0.0 = Surface at index 0, Index number of last surface = Surface at last index)
The tween factor range from one surface to the next surface in the list is:
Index number of a surface = the surface at that index, Index number of the next surface = the next surface in the list, factors between the surface index numbers will be the corresponding tweens.
A tween factor of 2.5 will result in a tween surface halfway between the surface at index 2 and the surface at index 3.||Boolean|
|Equalized||E||If True, tween distribution is evaluated along the tween path without considering the locations of the input surface set||Boolean|
|Weighted||W||If True, tween distribution is weighted by the input surface set and the tween path curvature||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|
|Refit||R||Optional Refit match method.
(No Integer or 0 = Off, Integer greater than 0 = On and surface degree of refit)
If an integer greater than zero, Refit match method is used if possible. When input surfaces are refit their control points are redistributed, added to, and removed from based on the surfaces curvature and the input integer degree, while trying to maintain their shapes. Refit results in tighter shaped tweens, with curvature based control point distribution.||Integer|
|Point Sample||P||Optional Point Sample match method.
(No Integer or 0 = Off, Integer greater than 0 = On and amount of sample points)
If an integer greater than zero, Point Sample match method is used. When input surfaces are sampled their control points are recreated by equally dividing the surface by the input integer point count. Point Sample results in looser shaped tweens, with uniform control point distribution.||Integer|
