[vtkusers] vtkPointLocator

[Alejandro Galindo Mateo]

Hello,

Thanks for the answer, vtkPointLocator is what I was looking for, but I have 
a problem.  When I used this class with  FindPointsWithinRadius I get an 
error:

   "vtkPointLocator [0x0249F520] No points to subdivide"

Can anybody tell me what I have to do?

Thanks for all
