Hello Jeff,

      Thanks for your interest on my question. I've taken a look to the 
examples provided for vtkTextActor (for Python, I only have TestText.py), but 
it seems to me that it can be used only to place text in a 2D world... and I 
have a 3D structured grid filled with scalars and many other Actors in my VTK 
window. Am I wrong? Can I use it also in a 3D world with 3D coordinates to 
positioning it?

Sorry for the probably silly question...

Andrea.
