[vtkusers] how to handle camera to travel inside a tube

[vaibhav agarwal]

Hi, 

I am trying to simulate a medical data. I have the
colun, it is a tube kind of structure. I have
generated the axis of this complex structure. The tube
like structure is hollow inside.

Now what i want, i want my camera to move along the
direction of axis. So basically there would be two
directions forward and backword along the axis, which
i want to bind to two keys.

How should i go about this problem? Any suggestion,
pointers or help is warmly welcomed.
