Constructor & Destructor Documentation

◆ OclDataSetToDataSetFilter()

mitk::OclDataSetToDataSetFilter::OclDataSetToDataSetFilter ( )

protected

OclDataSetToDataSetFilter Default constructor.

Definition at line 18 of file mitkOclDataSetToDataSetFilter.cpp.

References m_Output, and mitk::OclDataSet::New().

◆ ~OclDataSetToDataSetFilter()

mitk::OclDataSetToDataSetFilter::~OclDataSetToDataSetFilter ( )

protectedvirtual

Destructor.

Definition at line 23 of file mitkOclDataSetToDataSetFilter.cpp.

Member Function Documentation

◆ GetBytesPerElem()

int mitk::OclDataSetToDataSetFilter::GetBytesPerElem ( )

protectedvirtual

Get the memory size needed for each element.

Definition at line 38 of file mitkOclDataSetToDataSetFilter.cpp.

References m_CurrentSizeOutput.

◆ GetGPUOutput()

mitk::OclDataSet::Pointer mitk::OclDataSetToDataSetFilter::GetGPUOutput ( )

Returns a pointer to the graphics memory.

Use this method when executing two and more filters on the GPU for fast access. This method does not copy the data to RAM. It returns only a pointer.

Definition at line 27 of file mitkOclDataSetToDataSetFilter.cpp.

References m_Output.

◆ GetOutput()

void * mitk::OclDataSetToDataSetFilter::GetOutput ( void )

Returns an pointer to the filtered data.

Definition at line 32 of file mitkOclDataSetToDataSetFilter.cpp.

References mitk::OclFilter::m_CommandQue, and m_Output.

◆ InitExec()

bool mitk::OclDataSetToDataSetFilter::InitExec	(	cl_kernel	ckKernel,
		unsigned int *	dimensions,
		vcl_size_t	outputDataSize,
		unsigned int	outputBpE
	)

protected

InitExec Initialize the execution.

Parameters

ckKernel The GPU kernel.

Exceptions

mitk::Exception if something goes wrong.

Returns: True for success.
