First I'll thank you for your real-time-feedback.

I think that it is a common aspectation
that ResetCamera bring everything in view
whatever is the aspect-ratio
of the RenderWindow.
So in my modest opinion this behavoir is wrong.

Anyway

- Do you think that change implementation of
   vtkCamera::ComputePerspectiveTransform
   like I show in my previous mail
   may have some bad side-effect ?

- can you make vtkCamera::ComputePerspectiveTransform
   virtual ?

Many thanks -- Silvano
