[vtk-developers] Compute view bounds

[jojo1309]

Hi,

I'm new to VTK, so maybe my problem is very simple.

I can dispay a planesource, I can zoom in and out with the wheel mouse, and
I can pan it.

My problem know is that I would like to avoid pan or zoom if it goes outside
the planesource. I'd like the view to stay inside the planesource. (the view
stays orthogonal to the plane)

I was looking for a way to get the viewbounds and to block the pan or the
zoom if it goes outside, but maybe there's a better way.

Thanks a lot for your help, and sorry for my poor english....
