Detailed Description

extract subset of unstructured grid geometry

vtkExtractUnstructuredGrid is a general-purpose filter to extract geometry (and associated data) from an unstructured grid dataset. The extraction process is controlled by specifying a range of point ids, cell ids, or a bounding box (referred to as "Extent"). Those cells lying within these regions are sent to the output. The user has the choice of merging coincident points (Merging is on) or using the original point set (Merging is off).

Warning:: If merging is off, the input points are copied through to the output. This means unused points may be present in the output data. If merging is on, then coincident points with different point attribute values are merged.

virtual const char* vtkExtractUnstructuredGrid::GetClassName ( ) [virtual]

Reimplemented from vtkUnstructuredGridAlgorithm.

static int vtkExtractUnstructuredGrid::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 vtkUnstructuredGridAlgorithm.

virtual int vtkExtractUnstructuredGrid::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 vtkUnstructuredGridAlgorithm.

static vtkExtractUnstructuredGrid* vtkExtractUnstructuredGrid::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkUnstructuredGridAlgorithm.

void vtkExtractUnstructuredGrid::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.
