[vtkusers] Scale visibility

I am having a problem with the scale of my objects.  I have an overhead
view for users to select specific objects.  The problem I have is that
the area that the objects are spread out over is so large that the
objects don't show up (drawing as less than a pixel).  The size of the
are is:

min: X:188783 Y:3270 Z:569306
max: X:460554 Y:5375 Z:840257

and the camer info is:

Camera Pos : X:324669 Y:952404 Z:704782
Focal Point: X:324669 Y:4821   Z:704782                              

I know the numbers are large, but this is a geology vis program so I
need large scale.

Is there an easy way with VTK to make the object scale to a visible size
automatically?  I know I can set up an ad hoc method using scaling, but
I hope there is an easier way.  I need an answer fairly quick, since I
need to show this to a customer next week.
