Detailed Description

generate scalars from Euclidean norm of vectors

vtkVectorNorm is a filter that generates scalar values by computing Euclidean norm of vector triplets. Scalars can be normalized 0<=s<=1 if desired.

Note that this filter operates on point or cell attribute data, or both. By default, the filter operates on both point and cell data if vector point and cell data, respectively, are available from the input. Alternatively, you can choose to generate scalar norm values for just cell or point data.

virtual const char* vtkVectorNorm::GetClassName ( ) [virtual]

Reimplemented from vtkDataSetAlgorithm.

static int vtkVectorNorm::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 vtkDataSetAlgorithm.

virtual int vtkVectorNorm::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 vtkDataSetAlgorithm.

static vtkVectorNorm* vtkVectorNorm::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkDataSetAlgorithm.

void vtkVectorNorm::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 vtkDataSetAlgorithm.

static vtkVectorNorm* vtkVectorNorm::New ( ) [static]

Construct with normalize flag off.

Reimplemented from vtkDataSetAlgorithm.

virtual void vtkVectorNorm::SetNormalize ( int ) [virtual]

Specify whether to normalize scalar values.

virtual int vtkVectorNorm::GetNormalize ( ) [virtual]

Specify whether to normalize scalar values.

virtual void vtkVectorNorm::NormalizeOn ( ) [virtual]

Specify whether to normalize scalar values.

virtual void vtkVectorNorm::NormalizeOff ( ) [virtual]

Specify whether to normalize scalar values.

virtual void vtkVectorNorm::SetAttributeMode ( int ) [virtual]

Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

virtual int vtkVectorNorm::GetAttributeMode ( ) [virtual]

Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

void vtkVectorNorm::SetAttributeModeToDefault ( ) [inline]

Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

const char* vtkVectorNorm::GetAttributeModeAsString ( )

Control how the filter works to generate scalar data from the input vector data. By default, (AttributeModeToDefault) the filter will generate the scalar norm for point and cell data (if vector data present in the input). Alternatively, you can explicitly set the filter to generate point data (AttributeModeToUsePointData) or cell data (AttributeModeToUseCellData).

int vtkVectorNorm::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			`[protected, virtual]`

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.
