[vtkusers] Transform 3ds Modell

[Gopalakrishnan, Gowri]

You can access the actors from the importer. I tried it for VRML and it
worked. But if your model has many actors then you will have to individually
do them all. It can be tedious.
But if it is just for scaling or positioning (for your entire model instead
of 
Individual objects) then I think you can use the camera to achieve this
effect.
