Another way is to use vtkTextMapper with a vtkActor2D .The
you can specify the coordinate sytem through

vtkCoordinate* coord = _actor->GetPositionCoordinate();
coord->SetCoordinateSystemToWorld();
coord->SetValue( _x, _y, _z );

This works fine within our project. For a class example look
at the cvs repository of the homepage below. 
The files VtkText.h/VtkText.cc are located in the GUI/Visualization
directory.
