Detailed Description

interpolate a tuple of arbitrary size

This class is used to interpolate a tuple which may have an arbitrary number of components (but at least one component). The interpolation may be linear in form, or via a subclasses of vtkSpline.

To use this class, begin by specifying the number of components of the tuple and the interpolation function to use. Then specify at least one pair of (t,tuple) with the AddTuple() method. Next interpolate the tuples with the InterpolateTuple(t,tuple) method, where "t" must be in the range of (t_min,t_max) parameter values specified by the AddTuple() method (if not then t is clamped), and tuple[] is filled in by the method (make sure that tuple [] is long enough to hold the interpolated data).

You can control the type of interpolation to use. By default, the interpolation is based on a Kochanek spline. However, other types of splines can be specified. You can also set the interpolation method to linear, in which case the specified spline has no effect on the interpolation.

Warning: Setting the number of components or changing the type of interpolation causes the list of tuples to be reset, so any data inserted up to that point is lost. Bisection methods are used to speed up the search for the interpolation interval.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ New()

static vtkTupleInterpolator * vtkTupleInterpolator::New ( )

static

Instantiate the class.

◆ SetNumberOfComponents()

void vtkTupleInterpolator::SetNumberOfComponents ( int numComp )

Specify the number of tuple components to interpolate.

Note that setting this value discards any previously inserted data.

◆ GetNumberOfComponents()

virtual int vtkTupleInterpolator::GetNumberOfComponents ( )

virtual

Specify the number of tuple components to interpolate.

Note that setting this value discards any previously inserted data.

◆ GetNumberOfTuples()

int vtkTupleInterpolator::GetNumberOfTuples ( )

Return the number of tuples in the list of tuples to be interpolated.

◆ GetMinimumT()

double vtkTupleInterpolator::GetMinimumT ( )

Obtain some information about the interpolation range.

The numbers returned (corresponding to parameter t, usually thought of as time) are undefined if the list of transforms is empty. This is a convenience method for interpolation.

◆ GetMaximumT()

double vtkTupleInterpolator::GetMaximumT ( )

Obtain some information about the interpolation range.

The numbers returned (corresponding to parameter t, usually thought of as time) are undefined if the list of transforms is empty. This is a convenience method for interpolation.

◆ Initialize()

void vtkTupleInterpolator::Initialize ( )

Reset the class so that it contains no (t,tuple) information.

◆ AddTuple()

void vtkTupleInterpolator::AddTuple	(	double	t,
		double	tuple[]
	)

Add another tuple to the list of tuples to be interpolated.

Note that using the same time t value more than once replaces the previous tuple value at t. At least two tuples must be added to define an interpolation function.

◆ RemoveTuple()

void vtkTupleInterpolator::RemoveTuple ( double t )

Delete the tuple at a particular parameter t.

If there is no tuple defined at t, then the method does nothing.

◆ InterpolateTuple()

void vtkTupleInterpolator::InterpolateTuple	(	double	t,
		double	tuple[]
	)

Interpolate the list of tuples and determine a new tuple (i.e., fill in the tuple provided).

If t is outside the range of (min,max) values, then t is clamped. Note that each component of tuple[] is interpolated independently.

◆ SetInterpolationType()

void vtkTupleInterpolator::SetInterpolationType ( int type )

Specify which type of function to use for interpolation.

By default spline interpolation (SetInterpolationFunctionToSpline()) is used (i.e., a Kochanek spline) and the InterpolatingSpline instance variable is used to birth the actual interpolation splines via a combination of NewInstance() and DeepCopy(). You may also choose to use linear interpolation by invoking SetInterpolationFunctionToLinear(). Note that changing the type of interpolation causes previously inserted data to be discarded.

◆ GetInterpolationType()

virtual int vtkTupleInterpolator::GetInterpolationType ( )

virtual

Specify which type of function to use for interpolation.

By default spline interpolation (SetInterpolationFunctionToSpline()) is used (i.e., a Kochanek spline) and the InterpolatingSpline instance variable is used to birth the actual interpolation splines via a combination of NewInstance() and DeepCopy(). You may also choose to use linear interpolation by invoking SetInterpolationFunctionToLinear(). Note that changing the type of interpolation causes previously inserted data to be discarded.

◆ SetInterpolationTypeToLinear()

void vtkTupleInterpolator::SetInterpolationTypeToLinear ( )

inline

◆ SetInterpolatingSpline()

void vtkTupleInterpolator::SetInterpolatingSpline ( vtkSpline * )

If the InterpolationType is set to spline, then this method applies.

By default Kochanek interpolation is used, but you can specify any instance of vtkSpline to use. Note that the actual interpolating splines are created by invoking NewInstance() followed by DeepCopy() on the interpolating spline specified here, for each tuple component to interpolate.

◆ GetInterpolatingSpline()

virtual vtkSpline * vtkTupleInterpolator::GetInterpolatingSpline ( )

virtual

If the InterpolationType is set to spline, then this method applies.

By default Kochanek interpolation is used, but you can specify any instance of vtkSpline to use. Note that the actual interpolating splines are created by invoking NewInstance() followed by DeepCopy() on the interpolating spline specified here, for each tuple component to interpolate.
