SplineFunction 2D/3D• SplineFunction[range, internal] represents a spline created by SplineFit. • The SplineFunction accepts an argument within the range of the spline for evaluation at some point along the curve. • When given a single symbolic argument, an n-dimension SplineFunction evaluates to a list of n SplineFunction objects. This is useful when the spline is to be passed to a function that requires two or three separate parametric functions in a list. • SplineFunction objects can be used for Mech cam profiles. • Cubic splines have zeroth-, first-, and second-order continuity. • See also: ArcLength. Further Examples Load the Modeler2D package. Create a SplineFunction representing the path between a sequence of 2D points, and evaluate it halfway between the first and second points. Each end of the spline will have zero curvature.
