Detailed Description

create polygonal text

vtkVectorText generates vtkPolyData from an input text string. Besides the ASCII alphanumeric characters a-z, A-Z, 0-9, vtkVectorText also supports ASCII punctuation marks. (The supported ASCII character set are the codes (33-126) inclusive.) The only control character supported is the line feed character "\n", which advances to a new line.

To use thie class, you normally couple it with a vtkPolyDataMapper and a vtkActor. In this case you would use the vtkActor's transformation methods to position, orient, and scale the text. You may also wish to use a vtkFollower to orient the text so that it always faces the camera.

Member Function Documentation

static vtkVectorText* vtkVectorText::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkPolyDataAlgorithm.

static int vtkVectorText::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 vtkPolyDataAlgorithm.

virtual int vtkVectorText::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 vtkPolyDataAlgorithm.

static vtkVectorText* vtkVectorText::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkVectorText::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkVectorText* vtkVectorText::NewInstance

(

)

const

Reimplemented from vtkPolyDataAlgorithm.

void vtkVectorText::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 vtkVectorText::SetText

(

const char *

)

[virtual]

Set/Get the text to be drawn.

virtual char* vtkVectorText::GetText

(

)

[virtual]

Set/Get the text to be drawn.

int vtkVectorText::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		[protected, virtual]

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

Reimplemented from vtkPolyDataAlgorithm.
