Detailed Description

Divergence of a vector field.

Date:: 2002/01/22 15:32:21

Revision:: 1.29

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

vtkImageDivergence* vtkImageDivergence::New ( ) [static]

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

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

Reimplemented from vtkImageToImageFilter.

int vtkImageDivergence::IsTypeOf ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkImageToImageFilter.

virtual int vtkImageDivergence::IsA ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkImageToImageFilter.

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

Reimplemented from vtkImageToImageFilter.

void vtkImageDivergence::ComputeInputUpdateExtent ( int inExt[6],

int outExt[6]

) [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageDivergence::ExecuteInformation ( vtkImageData * inData,

vtkImageData * outData

) [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageDivergence::ExecuteInformation ( ) [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter.
Definition at line 63 of file vtkImageDivergence.h.
References vtkImageToImageFilter::ExecuteInformation().

void vtkImageDivergence::ThreadedExecute ( vtkImageData * inData,

vtkImageData * outData,

int ext[6],

int id

) [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.
Reimplemented from vtkImageToImageFilter.
