[vtkusers] Using PointLocator and insert points

[Charles Monty Burns]

Hello,

I will use the vtkPointLocator to detect wheather a point exist in a
special space in my polydata-mesh. If no one exist I will add one, but
the added point should be available to the locator for a further
search.

How can I do this? The point will be added to the mesh and should also
available to the locator.

Greetings
