Detailed Description

merge exactly coincident points

vtkMergePoints is a locator object to quickly locate points in 3D. The primary difference between vtkMergePoints and its superclass vtkPointLocator is that vtkMergePoints merges precisely coincident points and is therefore much faster.

int vtkMergePoints::InsertUniquePoint ( const double  x[3],
vtkIdType ptId

overridevirtual

Determine whether point given by x[3] has been inserted into points list.

Return 0 if point was already in the list, otherwise return 1. If the point was not in the list, it will be ADDED. In either case, the id of the point (newly inserted or not) is returned in the ptId argument. Note this combines the functionality of IsInsertedPoint() followed by a call to InsertNextPoint().

Implements vtkIncrementalPointLocator.
