[vtkusers] Importing a set of coloured lines

[David Netherway]

I have a wireframe model in wrl format consisting of a set of lines with a
colour associated with each line.

I can read the file in and display it using the example VRMLImporter by
simply changing the importer filename.

But I wish to add the lines to an existing renderer. How can I access the
lines and colours for adding the actors to the renderer?

Does anyone have suggestions as to a reasonable way to proceed?

Thanks, David
