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

static int vtkSplineFilter::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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.

virtual int 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.

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

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkSplineFilter::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkSplineFilter* vtkSplineFilter::NewInstance ( ) const

Reimplemented from vtkPolyDataAlgorithm.

void vtkSplineFilter::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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.

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.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkSplineFilter::SetMaximumNumberOfSubdivisions ( int ) [virtual]

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

virtual int vtkSplineFilter::GetMaximumNumberOfSubdivisions ( ) [virtual]

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

virtual void vtkSplineFilter::SetSubdivide ( int ) [virtual]

Specify how the number of subdivisions is determined.

virtual int vtkSplineFilter::GetSubdivide ( ) [virtual]

Specify how the number of subdivisions is determined.

void vtkSplineFilter::SetSubdivideToSpecified ( ) [inline]

Specify how the number of subdivisions is determined.

Definition at line 81 of file vtkSplineFilter.h.

void vtkSplineFilter::SetSubdivideToLength ( ) [inline]

Specify how the number of subdivisions is determined.

Definition at line 83 of file vtkSplineFilter.h.

const char* vtkSplineFilter::GetSubdivideAsString ( )

Specify how the number of subdivisions is determined.

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().

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().

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.

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.

virtual void vtkSplineFilter::SetSpline ( vtkSpline * ) [virtual]

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

virtual vtkSpline* vtkSplineFilter::GetSpline ( ) [virtual]

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