[vtkusers] Re: vtkCamera::SetViewPlaneNormal how to replace

[Jaco Schieke]

Thanks for the help.  The solution that did the trick for me was:

from Numeric import array
camera.SetFocalPoint(tuple(plane_origin))
camera.SetPosition(plane_origin+distance*array(normal))
ren.ResetCameraClippingRange()
camera.SetViewUp((0,0,1))
