[vtkusers] How to translate a scene

[David Brayford]

Hi,

I am trying to translate a scene along one axis and would normally
translate the camera position rather than apply the translation to the
whole scene. However, I don't know the commands to do the equivalent
of glTranslate(20, 0, 0); or the equivalent rotation glRotate(theta,
1, 0, 0). I am finding the transformations in VTK difficult to
implement, even though I know the required mathematical operations.

Thanks
David
