Member Function Documentation

vtkKWEGPUImageAlgorithmDriver::vtkTypeRevisionMacro	(	vtkKWEGPUImageAlgorithmDriver	,
		vtkImageAlgorithm
	)

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

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkKWEImageGradientMagnitude.

vtkRenderWindow* vtkKWEGPUImageAlgorithmDriver::GetContext ( )

Get/Set the context. Note that the context is not reference counted.

virtual void vtkKWEGPUImageAlgorithmDriver::SetContext ( vtkRenderWindow * ) [virtual]

Get/Set the context. Note that the context is not reference counted.

virtual ExtentTypes vtkKWEGPUImageAlgorithmDriver::GetSplitMode	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, pure virtual]`

The method should return how the streamer should break up extents. This is not much different from the split mode specified on vtkExtentTranslator.

Implemented in vtkKWEImageGradientMagnitude.

virtual int vtkKWEGPUImageAlgorithmDriver::MapOutputExtentToInput	(	int	input_extent[6],
		int	port,
		int	connection,
		vtkInformation *	inInfo,
		const int	output_extent[6]
	)			`[protected, pure virtual]`

Given the output_extent that we need to produce, what extents does the subclass need from the input on the indicated (port, connection). Return value is a an int indicating the minimum dimensionality of the texture created for the corresponding input. Returns value 0 (or less) indicates error.

Implemented in vtkKWEImageGradientMagnitude.

virtual bool vtkKWEGPUImageAlgorithmDriver::InitializeExecution	(	vtkInformation *	vtkNotUsedrequest,
		vtkInformationVector **	vtkNotUsedinputVector,
		vtkInformationVector *	vtkNotUsedoutputVector
	)			`[inline, protected, virtual]`

Gives the subclasses an opportunity to do some initialization before the looping begins.

Definition at line 96 of file vtkKWEGPUImageAlgorithmDriver.h.

virtual bool vtkKWEGPUImageAlgorithmDriver::Execute	(	vtkBuses *	upBuses,
		vtkDataTransferHelper *	downBus
	)			`[protected, pure virtual]`

Actual execution method.

Implemented in vtkKWEImageGradientMagnitude.

virtual void vtkKWEGPUImageAlgorithmDriver::Execute ( ) [inline, protected, virtual]

Actual execution method.

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkKWEImageGradientMagnitude.

Definition at line 106 of file vtkKWEGPUImageAlgorithmDriver.h.

virtual bool vtkKWEGPUImageAlgorithmDriver::FinalizeExecution	(	vtkInformation *	vtkNotUsedrequest,
		vtkInformationVector **	vtkNotUsedinputVector,
		vtkInformationVector *	vtkNotUsedoutputVector
	)			`[inline, protected, virtual]`

Gives the subclasses an opportunity to do some cleanup after the looping ends.

Definition at line 112 of file vtkKWEGPUImageAlgorithmDriver.h.

virtual int vtkKWEGPUImageAlgorithmDriver::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, virtual]`

Actual execution. Subclasses should not override this method. They should override Execute() instead.

Reimplemented from vtkImageAlgorithm.

int vtkKWEGPUImageAlgorithmDriver::RequestUpdateExtent	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, virtual]`
