Natural is a setting for the EndConditions option for SplineFit that specifies that the curvature of the spline will be zero at the ends.

• The alternatives to Natural are Closed or a list of two direction vectors.
• See also: SplineFunction.

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.

The spline is a 2D parametric function, and can be plotted as such.

Here is a spline with the ends closed upon themselves.

Here is a spline with specific direction vectors at the ends.

Here are all three splines shown together.

Here is a SplineFunction with values given for the independent variable at each knot point.

Here is the arc length of the spline, also expressed as a function of the independent variable.
