[vtkusers] vtkPointLocator

[Bryn Lloyd]

Hi


I would like to use the vtkPointLocator in the point insertion mode, 
i.e. I would like to incrementally insert points and search for them.

The incremental point insertion mode works with the functions: 
InsertNextPoint, IsInsertedPoint, FindClosestInsertedPoint


There is, however, no method to search for the N closest points.

I tried FindClosestNPoints with no success. I tried first calling 
BuildLocator on the locator but get error messages (No points to 
subdivide).
What do I need to do, in order to use the function FindClosestNPoints in 
point insertion mode?



Another function that is "missing" is point removal, although I can 
probably live with this.

Is there a better code for doing what I need?



Thanks for any suggestions & help.
