[vtkusers] vtkCamera Dolly & FocalPoint

[Maurizio Turatti]

Hi,
I want to move my camera over a terrain, like a flight sym (more like an
helicopter). I have a question about the Dolly method, because the focal point
distance decreases as I Dolly the camera, until I can can't move, because
distance is too small. How can I translate my camera on a parallel plane over my
terrain, keeping the focal point on the terrain but at constant distance from
the camera? (I'm using vtk 3.1.2 nightly 5-9-2000)

Thanks for every hint,
Maurizio
