Member Function Documentation

◆ AddSourceFile()

void mitk::OclFilter::AddSourceFile ( const char * filename )

Add a source file from the resource files to the OpenCL shader file list. Multiple files can be added to the list.

Parameters

filename of the file in the resource system

◆ CompileSource()

void mitk::OclFilter::CompileSource ( )

protected

Compile the program source.

◆ ExecuteKernel()

bool mitk::OclFilter::ExecuteKernel	(	cl_kernel	kernel,
		unsigned int	workSizeDim
	)

protected

Execute the given kernel on the OpenCL Index-Space defined by the local and global work sizes.

◆ ExecuteKernelChunks()

bool mitk::OclFilter::ExecuteKernelChunks	(	cl_kernel	kernel,
		unsigned int	workSizeDim,
		size_t *	chunksDim
	)

protected

Execute the given kernel on the OpenCL Index-Space defined by the local and global work sizes, but divide it into chunks of dimension chunksDim.

virtual unsigned long mitk::OclFilter::GetDeviceMemory ( )

virtual

Returns the amount of global memory of the used device in bytes.

◆ GetModule()

virtual us::Module* mitk::OclFilter::GetModule ( )

protectedpure virtual

Get the Module of the filter. Needs to be implemented by every subclass. The filter will load the OpenCL sourcefiles from this module context.

Implemented in mitk::OclBinaryThresholdImageFilter.

◆ Initialize()

bool mitk::OclFilter::Initialize ( )

protected

Initialize all necessary parts of the filter.

The Initialize() method creates the command queue and the m_clProgram. The program is either compiled from the given source or taken from the OclResourceManager if the program was compiled already.

virtual bool mitk::OclFilter::IsInitialized ( )

virtual

Returns true if the initialization was successfull.

Parameters

SourceCodeList	holds the sourcecode for every file as string, the SourceCodeSizeList holst the size of every file in bytes.
SourceCodeSizeList

Parameters

flags to the modulefolder that contains the gpuSource

◆ SetSourcePreambel()

void mitk::OclFilter::SetSourcePreambel ( const char * preambel )

protected

Add some source code on the beginning of the loaded source.

In this way, some preprocessor flags for the CL compiler can at the beginning of the filter

Parameters

preambel Source preambel for e.g. #define commands to be inserted into the OpenCL source

◆ SetWorkingSize()

void mitk::OclFilter::SetWorkingSize	(	unsigned int	locx,
		unsigned int	dimx,
		unsigned int	locy = `1`,
		unsigned int	dimy = `1`,
		unsigned int	locz = `1`,
		unsigned int	dimz = `1`
	)

protected

Set the working size for the following OpenCL kernel call.
