[vtkusers] How to associate character strings (textual lablels) with 3D points ?

Dear Giancarlo:

thank you very much for your reply ... I will think about this.

What I originally wanted was the string to be contained in the dataset,
because I have to send the points and their labels across network using
the vtkSocketCommunicator. I then want to render the string as 2D in the
overlay plane ...


Thanks in advance,
