[vtkusers] Using PointLocator and insert points

[Bryn Lloyd]

Hello,


For "normal" usage, where all points are added at once, you can setup 
the locator by passing it a dataset: 
vtkPointLocator::SetDataSet(vtkDataSet *)



For your usage you need to use the function 
vtkPointLocator::InitPointInsertion(vtkPoints *newPts, const double 
bounds[6])
This function expects a vtkPoints object and the bounds in which the 
point locator operates. It will not find points outside the bounds.
The vtkPoints could be shared by the locator and the polydata.
