Closed
2D/3D

• Closed is a setting for the EndConditions option for SplineFit that specifies that the slope and curvature of the spline at the two ends will be equal.

• To actually close the spline upon itself, the EndConditions->Closed option must be given and the last data point given to SplineFit must be identical to the first.
• The alternatives to Closed are Natural or a list of two direction vectors.
• See also: SplineFunction.

In[1]:=

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.

In[2]:=

Out[3]=

Out[4]=

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

In[5]:=

Out[5]=

Here is a spline with the ends closed upon themselves.

In[6]:=

Out[6]=

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

In[7]:=

Out[7]=

Here are all three splines shown together.

In[8]:=

Out[8]=

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