void FindClosestNPoints(int N, const double x[3], vtkIdList *result) override
Find the closest N points to a position.
void BuildLocatorInternal() override
This function is not pure virtual to maintain backwards compatibility.

Given a position x and a radius r, return the id of the point closest to the point in that radius.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard type and print methods.
void GenerateRepresentation(int level, vtkPolyData *pd) override
See vtkLocator interface documentation.
