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.

Implement the specific strategy.

Implements vtkFindCellStrategy.

◆ SetClosestNPoints()

◆ Initialize()

int vtkClosestPointStrategy::Initialize
override

Provide the necessary initialization method (see superclass for more information).

This method sets up the point locator, vtkPointSet relationship. It will use the vtkPointSet's default locator if not defined by SetPointLocator() below.
