SplineFunction[type, domain, internal]
represents a spline function created by the SplineFit function parametrizing a curve with the parameter in the specified domain. When given a parameter value as an argument it returns the corresponding point on the curve.
  • The SplineFunction object generated with SplineFit[{pt1, pt2, ...}, type] is parametrized such that a parameter value of 0 corresponds to pt1, 1 corresponds to pt2, etc.
