[vtkusers] Zooming etc

[James C. Robinson]

Dear All,

Has anyone any ideas on how to get more or different control over a vtk
render window. For example, is it possible to have a classic zoom function
whereby the user defines a rectangle to which the image will zoom (by moving
the camera)?

Also, how does one get a set of axis to sit in the corner of the screen
denoting x,y,z - never moving (just rotating as the camera position rotates)
and never changing scale (as the camera zooms).

Regards,

Jim
