EndConditions is an option for SplineFit that is used to specify the end conditions of the spline.
EndConditions can be set to Natural, Closed, or a list of two vectors {{x1, y1}, {x2, y2}} (2D) or {{x1, y1, z1}, {x2, y2, z2}} (3D) specifying the tangency direction at the beginning and end of the spline, respectively.

• If a list of two vectors is given, both their magnitude and direction are significant.
• The default setting is EndConditions->Natural.

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.
