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

[Markus Neff]

Dear mailinglist:

I am new to VTK and I want to associate textual labels with 3D points in
a dataset. Is there a standard way of doing this or do I have to write
my own "vtkLabeledDataMapperString" which gets the string char by char
from field data and renders them in the overlay plane ?

Thanks in advance,
Markus Neff
