Detailed Description

generate uniformly subdivided polylines from a set of input polyline using a vtkSpline

vtkSplineFilter is a filter that generates an output polylines from an input set of polylines. The polylines are uniformly subdivided and produced with the help of a vtkSpline class that the user can specify (by default a vtkCardinalSpline is used). The number of subdivisions of the line can be controlled in several ways. The user can either specify the number of subdivisions or a length of each subdivision can be provided (and the class will figure out how many subdivisions is required over the whole polyline). The maximum number of subdivisions can also be set.

The output of this filter is a polyline per input polyline (or line). New points and texture coordinates are created. Point data is interpolated and cell data passed on. Any polylines with less than two points, or who have coincident points, are ignored.

Member Function Documentation

◆ IsTypeOf()

static vtkTypeBool vtkSplineFilter::IsTypeOf ( const char * type )

static

◆ IsA()

virtual vtkTypeBool vtkSplineFilter::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

◆ SafeDownCast()

static vtkSplineFilter * vtkSplineFilter::SafeDownCast ( vtkObjectBase * o )

static

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkSplineFilter::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkPolyDataAlgorithm.

◆ NewInstance()

vtkSplineFilter * vtkSplineFilter::NewInstance ( ) const

◆ PrintSelf()

void vtkSplineFilter::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkPolyDataAlgorithm.

◆ New()

static vtkSplineFilter * vtkSplineFilter::New ( )

static

Construct the class with no limit on the number of subdivisions and using an instance of vtkCardinalSpline to perform interpolation.

◆ SetMaximumNumberOfSubdivisions()

virtual void vtkSplineFilter::SetMaximumNumberOfSubdivisions ( int )

virtual

Set the maximum number of subdivisions that are created for each polyline.

◆ GetMaximumNumberOfSubdivisions()

virtual int vtkSplineFilter::GetMaximumNumberOfSubdivisions ( )

virtual

Set the maximum number of subdivisions that are created for each polyline.

◆ SetSubdivide()

virtual void vtkSplineFilter::SetSubdivide ( int )

virtual

Specify how the number of subdivisions is determined.

◆ GetSubdivide()

virtual int vtkSplineFilter::GetSubdivide ( )

virtual

Specify how the number of subdivisions is determined.

◆ SetSubdivideToSpecified()

void vtkSplineFilter::SetSubdivideToSpecified ( )

inline

Specify how the number of subdivisions is determined.

Definition at line 124 of file vtkSplineFilter.h.

◆ SetSubdivideToLength()

void vtkSplineFilter::SetSubdivideToLength ( )

inline

Specify how the number of subdivisions is determined.

Definition at line 125 of file vtkSplineFilter.h.

◆ GetSubdivideAsString()

const char * vtkSplineFilter::GetSubdivideAsString ( )

Specify how the number of subdivisions is determined.

◆ SetNumberOfSubdivisions()

virtual void vtkSplineFilter::SetNumberOfSubdivisions ( int )

virtual

Set the number of subdivisions that are created for the polyline.

This method only has effect if Subdivisions is set to SetSubdivisionsToSpecify().

◆ GetNumberOfSubdivisions()

virtual int vtkSplineFilter::GetNumberOfSubdivisions ( )

virtual

Set the number of subdivisions that are created for the polyline.

This method only has effect if Subdivisions is set to SetSubdivisionsToSpecify().

◆ SetLength()

virtual void vtkSplineFilter::SetLength ( double )

virtual

Control the number of subdivisions that are created for the polyline based on an absolute length.

The length of the spline is divided by this length to determine the number of subdivisions.

◆ GetLength()

virtual double vtkSplineFilter::GetLength ( )

virtual

Control the number of subdivisions that are created for the polyline based on an absolute length.

The length of the spline is divided by this length to determine the number of subdivisions.

◆ SetSpline()

virtual void vtkSplineFilter::SetSpline ( vtkSpline * )

virtual

Specify an instance of vtkSpline to use to perform the interpolation.

◆ GetSpline()

virtual vtkSpline * vtkSplineFilter::GetSpline ( )

virtual

Specify an instance of vtkSpline to use to perform the interpolation.
