Detailed Description

identify and fill holes in meshes

vtkFillHolesFilter is a filter that identifies and fills holes in input vtkPolyData meshes. Holes are identified by locating boundary edges, linking them together into loops, and then triangulating the resulting loops. Note that you can specify an approximate limit to the size of the hole that can be filled.

Warning:

Note that any mesh with boundary edges by definition has a topological hole. This even includes a reactangular grid (e.g., the output of vtkPlaneSource). In such situations, if the outer hole is filled, retriangulation of the hole will cause geometric overlap of the mesh. This can be prevented by using the hole size instance variable to prevent the larger holes from being triangulated.

Note this filter only operates on polygons and triangle strips. Vertices and polylines are passed through untouched.

Member Function Documentation

static vtkFillHolesFilter* vtkFillHolesFilter::New

(

)

[static]

Standard methods for instantiation, type information and printing.

Reimplemented from vtkPolyDataAlgorithm.

virtual const char* vtkFillHolesFilter::GetClassName

(

)

[virtual]

Reimplemented from vtkPolyDataAlgorithm.

static int vtkFillHolesFilter::IsTypeOf

(

const char *

type

)

[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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkFillHolesFilter::IsA

(

const char *

type

)

[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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataAlgorithm.

static vtkFillHolesFilter* vtkFillHolesFilter::SafeDownCast

(

vtkObject *

o

)

[static]

Reimplemented from vtkPolyDataAlgorithm.

void vtkFillHolesFilter::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 vtkPolyDataAlgorithm.

virtual void vtkFillHolesFilter::SetHoleSize

(

double

)

[virtual]

Specify the maximum hole size to fill. This is represented as a radius to the bounding circumsphere containing the hole. Note that this is an approximate area; the actual area cannot be computed without first triangulating the hole.

virtual double vtkFillHolesFilter::GetHoleSize

(

)

[virtual]

Specify the maximum hole size to fill. This is represented as a radius to the bounding circumsphere containing the hole. Note that this is an approximate area; the actual area cannot be computed without first triangulating the hole.

int vtkFillHolesFilter::RequestData	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			[protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.
