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

[Jaco Schieke]

I would like to do the same as Jan.  I have a plane (with a normal) at which I want the camera to look straight at.  Since
SetViewPlaneNormal is now deprecated, how do one go about this?

Thanks, and I hope it's third time lucky for this post.
