Detailed Description

This class helps to transform, export and import vtk point sets.

Note: As it is a pure transformer, all the methods are static.

◆ buildVtkPointSet()

vtkSmartPointer< vtkPointSet > VtkMeshUtil::buildVtkPointSet	(	std::string	vtkFileName,
		VtkPointSetType	whatIsIt = `UNKNOWN`
	)

static

Static method that could be used from anywhere to build a vtkPointSet from a vtk file.

Currently only vtkUnstructuredGrid, vtkPolyData and vtkStructuredGrid are supported. To support more file format build a specific component extension!

Parameters

vtkFileName	the name of the vtk file to use as input
whatIsIt	(optional) if you already know the file type, it is quicker to give it here

Returns: the new vtkPointSet

static

static method to get the vtk header string from a vtk file

Parameters

vtkFileName	the name of the vtk file to get the header from
whatIsIt	(optional) if you already know the file type, it is quicker to give it here

◆ saveGeometryToFile()

bool VtkMeshUtil::saveGeometryToFile	(	camitk::Geometry *	g,
		std::string	vtkFileName
	)

static

Static method that could be use to store any Geometry instance in a vtk file.

Parameters

g	the Geometry instance to save
vtkFileName	the name of the vtk file to use as output

Returns: true if everything was saved ok.

	)

static

save a vtkDataset into a given file.

Parameters

ps	the vtkPointSet to save
fname	the file name to save to
oname	the name of the object to save (wrote in the header)

◆ savePolyDataToFile()

void VtkMeshUtil::savePolyDataToFile	(	vtkSmartPointer< vtkPolyData >	pData,
		std::string	fname,
		std::string	oname = `""`
	)

static

save a given vtkPolyData into a given file

Parameters

pData	the vtkPolyData to save
fname	the file name to save to
oname	the name of the object to save (wrote in the header)

◆ saveStructuredGridToFile()

void VtkMeshUtil::saveStructuredGridToFile	(	vtkSmartPointer< vtkStructuredGrid >	sGrid,
		std::string	fname,
		std::string	oname = `""`
	)

static

save a given vtkStructuredGrid into a given file

Parameters

sGrid	the vtkStructuredGrid to save
fname	the file name to save to
oname	the name of the object to save (wrote in the header)

◆ saveUnstructuredGridToFile()

void VtkMeshUtil::saveUnstructuredGridToFile	(	vtkSmartPointer< vtkUnstructuredGrid >	uGrid,
		std::string	fname,
		std::string	oname = `""`
	)

static

save a given vtkUnstructuredGrid into a given file

Parameters

uGrid	the vtkUnstructuredGrid to save
fname	the file name to save to
oname	the name of the object to save (wrote in the header)

◆ typeOf() [1/2]

VtkMeshUtil::VtkPointSetType VtkMeshUtil::typeOf ( std::string vtkFileName )

static

static method that tells you what kind of vtk file it is.

If it returns VtkManager::UNKNOWN, it means the vtk data are not supported.

Parameters

vtkFileName the name of the vtk file to check

Returns: the VtkPointSetType of the file given in parameter

◆ typeOf() [2/2]

VtkMeshUtil::VtkPointSetType VtkMeshUtil::typeOf ( vtkSmartPointer< vtkPointSet > aPointSet )

static

static method that tells you what kind of vtkPointSet it is.

If it returns VtkManager::UNKNOWN, this is an unsupported type of vtkPointSet.

Parameters

aPointSet the pointset data to analyze

Returns: the VtkPointSetType of the file given in parameter

References POLY_DATA, STRUCTURED_GRID, UNKNOWN, and UNSTRUCTURED_GRID.

◆ vtkPointSetToVtkPolyData()

vtkSmartPointer< vtkPolyData > VtkMeshUtil::vtkPointSetToVtkPolyData ( vtkSmartPointer< vtkPointSet > aPointSet )

static

static method that transform any vtkPointSet to a vtkPolyData.

If the vtkPointSet is already a vtkPolyData, nothing is done.
If the vtkPointSet is a vtkUnstructuredGrid or vtkStructuredGrid, then it uses a vtkDataSetSurfaceFilter to extract the surface
Parameters

aPointSet the vtkPointSet to transform

Returns
the vtkPolyData corresponding
