[vtkusers] VRML

[Tom Citriniti]

The VRML Importer has the abilility to return an object by the DEF name used
in the class. Check out the class page and look at the method that returns
an object by name. This is broken in the current version. I have a fixed
version I have not checked back into CVS. Let me know if this will help you.
Otherwise you can simply rip through all the actors and output the
underlying Polydata objects and pick the one you want.
