void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual void DeepCopy(vtkSpline *s)
Deep copy of spline data.
virtual void Compute()=0
Compute the coefficients for the spline.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
computes an interpolating spline using a a Cardinal basis.
