Detailed Description

Interpolation model for transformations.

Between the data points, the interpolation uses the neighboring points. Outside the range spanned by the points, we extrapolate using a line through the first and the last point.

Different types of interpolation (controlled by the parameter interpolation_type) are supported: "linear", "polynomial", "cspline", and "akima". Note that the number of required data points may differ between types.
