[vtkusers] Scaling question

[Paul Tait]

I'm displayind a surface and by using the Scale(x, y, z) method I'm
deforming it to exagerate the Z axis ie. making it bumpier or flatter

As I do this I've got 2 problems

1. My vtkAxes/vtkTubeFilter stay where I originally placed them using
SetOrigin()

2. the surface moves off the top/bottom of the window

So

1. How can I sync my axes to the surface

2. how can I keep my camera centred on the surface


Thanks Paul Tait
