Detailed Description

extract cells that lie either entirely inside or outside of a specified implicit function

vtkExtractGeometry extracts from its input dataset all cells that are either completely inside or outside of a specified implicit function. Any type of dataset can be input to this filter. On output the filter generates an unstructured grid.

To use this filter you must specify an implicit function. You must also specify whethter to extract cells lying inside or outside of the implicit function. (The inside of an implicit function is the negative values region.) An option exists to extract cells that are neither inside or outside (i.e., boundary).

A more efficient version of this filter is available for vtkPolyData input. See vtkExtractPolyDataGeometry.

Member Function Documentation

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

Reimplemented from vtkUnstructuredGridAlgorithm.

static int vtkExtractGeometry::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 vtkExtractGeometry::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 vtkExtractGeometry* vtkExtractGeometry::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkUnstructuredGridAlgorithm.

void vtkExtractGeometry::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 vtkUnstructuredGridAlgorithm.

static vtkExtractGeometry* vtkExtractGeometry::New ( ) [static]

Construct object with ExtractInside turned on.

Reimplemented from vtkUnstructuredGridAlgorithm.

unsigned long vtkExtractGeometry::GetMTime ( ) [virtual]

Return the MTime taking into account changes to the implicit function

Reimplemented from vtkObject.

virtual void vtkExtractGeometry::SetImplicitFunction ( vtkImplicitFunction * ) [virtual]

Specify the implicit function for inside/outside checks.

virtual vtkImplicitFunction* vtkExtractGeometry::GetImplicitFunction ( ) [virtual]

Specify the implicit function for inside/outside checks.

virtual void vtkExtractGeometry::SetExtractInside ( int ) [virtual]

Boolean controls whether to extract cells that are inside of implicit function (ExtractInside == 1) or outside of implicit function (ExtractInside == 0).

virtual int vtkExtractGeometry::GetExtractInside ( ) [virtual]

Boolean controls whether to extract cells that are inside of implicit function (ExtractInside == 1) or outside of implicit function (ExtractInside == 0).

virtual void vtkExtractGeometry::ExtractInsideOn ( ) [virtual]

Boolean controls whether to extract cells that are inside of implicit function (ExtractInside == 1) or outside of implicit function (ExtractInside == 0).

virtual void vtkExtractGeometry::ExtractInsideOff ( ) [virtual]

Boolean controls whether to extract cells that are inside of implicit function (ExtractInside == 1) or outside of implicit function (ExtractInside == 0).

virtual void vtkExtractGeometry::SetExtractBoundaryCells ( int ) [virtual]
