Member Function Documentation

static int vtkAMRUtilities::IsTypeOf

(

const char *

name

)

[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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkAMRUtilities::IsA

(

const char *

name

)

[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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkAMRUtilities* vtkAMRUtilities::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkAMRUtilities::NewInstanceInternal

vtkAMRUtilities* vtkAMRUtilities::NewInstance

(

)

const

Reimplemented from vtkObject.

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

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static void vtkAMRUtilities::StripGhostLayers	(	vtkOverlappingAMR *	ghostedAMRData,
		vtkOverlappingAMR *	strippedAMRData,
		vtkMultiProcessController *	myController = NULL
	)		[static]

This method detects and strips partially overlapping cells from a given AMR dataset. If ghost layers are detected, they are removed and new grid instances are created to represent the stripped data-set otherwise, each block is shallow-copied. .SECTION Assumptions 1) The ghosted AMR data must have complete metadata information.

static bool vtkAMRUtilities::HasPartiallyOverlappingGhostCells

(

vtkOverlappingAMR *

amr

)

[static]

A quick test of whether partially overlapping ghost cells exist. This test starts from the highest-res boxes and checks if they have partially overlapping cells. The code returns with true once partially overlapping cells are detected. Otherwise, false is returned.

static void vtkAMRUtilities::DistributeProcessInformation	(	vtkOverlappingAMR *	amr,
		vtkMultiProcessController *	myController,
		std::vector< int > &	ProcessMap
	)		[static]

Compute map from block indices to process ids

static void vtkAMRUtilities::BlankCells	(	vtkOverlappingAMR *	amr,
		vtkMultiProcessController *	myController
	)		[static]

Blank cells in overlapping AMR

static void vtkAMRUtilities::CopyFieldsWithinRealExtent	(	int	realExtent[6],
		vtkUniformGrid *	ghostedGrid,
		vtkUniformGrid *	strippedGrid
	)		[static, protected]

Given the real-extent w.r.t. the ghosted grid, this method copies the field data (point/cell) data on the stripped grid.

static void vtkAMRUtilities::CopyFieldData	(	vtkFieldData *	target,
		vtkIdType	targetIdx,
		vtkFieldData *	source,
		vtkIdType	sourceIdx
	)		[static, protected]

Copies the fields from the given source to the given target.

static vtkUniformGrid* vtkAMRUtilities::StripGhostLayersFromGrid	(	vtkUniformGrid *	grid,
		int	ghost[6]
	)		[static, protected]

Strips ghost layers from the given grid according to the given ghost vector which encodes the number of cells to remote from each of the 6 sides {imin,imax,jmin,jmax,kmin,kmax}. For example, a ghost vector of {0,2,0,2,0,0} would indicate that there exist 2 ghost cells on the imax and jmax side.
