Vector Interpolation¶
Functionality¶
Performs linear or cubic spline interpolation based on input points by creating a function x,y,z = f(t) with t=[0,1]. The interpolation is based on the distance between the input points.

Parameters¶
Mode : Interpolation method. Can be Linear or Cubic
Cyclic: Treat the input vertices as a cyclic path.
Int Range: When activated the node will expect a Integer Value in the ‘t’ input and will create a range from 0 to 1 with the inputted steps.
End Point: (Only when Int Range is activated) If active the generated range will exclude 1. Useful when the value 0 and 1 of the interpolation is the same
Extra Parameters¶
Knot Mode: Used for different cubic interpolations. Can be ‘Manhattan’, ‘Euclidean’, ‘Points’ and ‘Chebyshev’
List Match: How List should be matched
Output Numpy: Outputs numpy arrays in stead of regular python lists (makes node faster)

Notes¶
The node doesn’t extrapolate. Values outside of [0, 1] are ignored.
