a simple class to control print indentation
Definition: vtkIndent.h:40
abstract base class for most VTK objects
Definition: vtkObject.h:63
Defines a 1D piecewise function.
spline abstract class for interpolating splines
Definition: vtkSpline.h:63
interpolate a tuple of arbitrary size
static vtkTupleInterpolator * New()
Instantiate the class.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void InterpolateTuple(double t, double tuple[])
Interpolate the list of tuples and determine a new tuple (i.e., fill in the tuple provided).
double GetMaximumT()
Obtain some information about the interpolation range.
vtkPiecewiseFunction ** Linear
void SetNumberOfComponents(int numComp)
Specify the number of tuple components to interpolate.
void RemoveTuple(double t)
Delete the tuple at a particular parameter t.
void Initialize()
Reset the class so that it contains no (t,tuple) information.
void AddTuple(double t, double tuple[])
Add another tuple to the list of tuples to be interpolated.
double GetMinimumT()
Obtain some information about the interpolation range.
~vtkTupleInterpolator() override
void SetInterpolationTypeToSpline()
Specify which type of function to use for interpolation.
void InitializeInterpolation()
void SetInterpolatingSpline(vtkSpline *)
If the InterpolationType is set to spline, then this method applies.
void SetInterpolationType(int type)
Specify which type of function to use for interpolation.
void SetInterpolationTypeToLinear()
Specify which type of function to use for interpolation.
int GetNumberOfTuples()
Return the number of tuples in the list of tuples to be interpolated.
