vtkCamera.cxx states that the perspective transform matrix is used in
converting between view and world coordinates. Since the camera view
transform is not aware of the viewport, I'd guess you're right on the
While we're on camera docs ... the .h file for Elevation() states
Rotate the camera about the cross product of the direction of projection
and the view up vector centered on the focal point.
and the .cxx file
Rotate the camera about the cross product of the NEGATIVE of the
direction of projection and the view up vector centered on the focal
I believe the .cxx is correct.
Hope these corrections make to the latest docs.
