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.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkIncrementalPointLocator.
Reimplemented in vtkSMPMergePoints.
Determine whether point given by x[3] has been inserted into points list.
Return id of previously inserted point if this is true, otherwise return -1.
Implements vtkIncrementalPointLocator.
Determine whether or not a given point has been inserted.
Return the id of the already inserted point if true, else return -1. InitPointInsertion() should have been called in advance.
Implements vtkIncrementalPointLocator.
Definition at line 50 of file vtkMergePoints.h.
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.
