The 3D Text source can be used to add polygonal text into the 3D scene. By default, the text will have an origin of (0,0,0) and will lie on the z=0 plane. The text can be translated, rotated, and scaled using the Actor control area of the Display tab for this source, and it can be interactively positioned using the Move operation of the camera. The object created by this source is a vtkVectorText object, and the output of this source is vtkPolyData. An example of 3D Text is given below.
The 3D Text source has only one parameter:
