[vtkusers] Importing VRML into a vtkAssembly

[david ignacio]

Is it possible, or is there any clean way of importing a VRML file
into a vtkAssembly?  The current vtkVRMLImporter just dumps everything
into the current vtkRenderer without allowing you to have any real
control over it.

The motivation behind this is that I have pretty large VRML files that
I want to load into multiple vtkRenderers without having to have more
than one copy in memory.  I also want to be able to add and remove the
vrml files from the Renderers dynamically.

Does anyone have any ideas of how to solve this?  Or is a re-write of
the vtkImporter Classes required?

Thanks
Dave
