[vtk-developers] vtkPlane non-static wrappers

[Francois Bertel]

That would be more object-oriented for sure. Go for it.

Just be careful that you cannot just pass the normal of the object to
the static method as I don't see in the documentation of the class any
class invariant stating that the magnitude of the normal has to be 1.
On the contrary, the static method DistanceToPlane() explicitly has
the magnitude of the normal to be 1  as a pre-condition.
