Detailed Description

implement a specific vtkPointSet::FindCell() strategy based on the N closest points

vtkClosestNPointsStrategy is implements a FindCell() strategy based on locating the closest N points in a dataset, and then searching attached cells. This class extends its superclass vtkClosestPointStrategy by looking at the additional N points.
