static

◆ IsA()

virtual vtkTypeBool vtkBillboardTextActor3D::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 vtkProp3D.

Reimplemented in vtkOpenGLBillboardTextActor3D.

◆ PrintSelf()

void vtkBillboardTextActor3D::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkObjectBase.

Reimplemented in vtkOpenGLBillboardTextActor3D.

◆ GetActors()

void vtkBillboardTextActor3D::GetActors ( vtkPropCollection * )

overridevirtual

For some exporters and other other operations we must be able to collect all the actors or volumes.

These methods are used in that process. In case the viewport is not a consumer of this prop: call UpdateGeometry() first for updated viewport-specific billboard geometry.

Reimplemented from vtkProp.

◆ UpdateGeometry()

void vtkBillboardTextActor3D::UpdateGeometry ( vtkViewport * vp )

Updates the billboard geometry without performing any rendering, to assist GetActors().

◆ SetInput()

void vtkBillboardTextActor3D::SetInput ( const char * in )

The UTF-8 encoded string to display.

◆ GetInput()

virtual char * vtkBillboardTextActor3D::GetInput ( )

virtual

The UTF-8 encoded string to display.

◆ GetDisplayOffset() [1/3]

virtual int * vtkBillboardTextActor3D::GetDisplayOffset ( )

virtual

Can be used to set a fixed offset from the anchor point.

Use display coordinates.

◆ GetDisplayOffset() [2/3]

virtual void vtkBillboardTextActor3D::GetDisplayOffset	(	int &	,
		int &
	)

virtual

Can be used to set a fixed offset from the anchor point.

Use display coordinates.

◆ GetDisplayOffset() [3/3]

virtual void vtkBillboardTextActor3D::GetDisplayOffset ( int [2] )

virtual

Can be used to set a fixed offset from the anchor point.

Use display coordinates.

◆ SetDisplayOffset() [1/2]

virtual void vtkBillboardTextActor3D::SetDisplayOffset	(	int	,
		int
	)

virtual

Can be used to set a fixed offset from the anchor point.

Use display coordinates.

◆ SetDisplayOffset() [2/2]

void vtkBillboardTextActor3D::SetDisplayOffset ( int [2] )

Can be used to set a fixed offset from the anchor point.

Use display coordinates.

◆ SetTextProperty()

void vtkBillboardTextActor3D::SetTextProperty ( vtkTextProperty * tprop )

The vtkTextProperty object that controls the rendered text.

◆ GetTextProperty()

virtual vtkTextProperty * vtkBillboardTextActor3D::GetTextProperty ( )

virtual

The vtkTextProperty object that controls the rendered text.
