Detailed Description

Divergence of a vector field.

vtkImageDivergence takes a 3D vector field and creates a scalar field which which represents the rate of change of the vector field. The definition of Divergence: Given V = P(x,y,z), Q(x,y,z), R(x,y,z), Divergence = dP/dx + dQ/dy + dR/dz.

Member Function Documentation

static vtkImageDivergence* vtkImageDivergence::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

static int vtkImageDivergence::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 vtkThreadedImageAlgorithm.

virtual int vtkImageDivergence::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 vtkThreadedImageAlgorithm.

static vtkImageDivergence* vtkImageDivergence::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkThreadedImageAlgorithm.

virtual vtkObjectBase* vtkImageDivergence::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkThreadedImageAlgorithm.

vtkImageDivergence* vtkImageDivergence::NewInstance

(

)

const

Reimplemented from vtkThreadedImageAlgorithm.

virtual int vtkImageDivergence::RequestUpdateExtent	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)		[protected, virtual]

Subclasses can reimplement this method to translate the update extent requests from each output port into update extent requests for the input connections.

Reimplemented from vtkImageAlgorithm.

virtual int vtkImageDivergence::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		[protected, virtual]

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

void vtkImageDivergence::ThreadedExecute	(	vtkImageData *	inData,
		vtkImageData *	outData,
		int	ext[6],
		int	id
	)		[protected, virtual]

Reimplemented from vtkThreadedImageAlgorithm.
