|
||
|
|
* @brief direct / check-free point insertion.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* As a special sub-class of vtkPointLocator, vtkNonMergingPointLocator is
|
||
|
|
* intended for direct / check-free insertion of points into a vtkPoints
|
||
|
|
* object. In other words, any given point is always directly inserted.
|
||
|
|
* The name emphasizes the difference between this class and its sibling
|
||
|
|
* class vtkMergePoints in that the latter class performs check-based zero
|
||
|
|
* tolerance point insertion (or to 'merge' exactly duplicate / coincident
|
||
|
|
* points) by exploiting the uniform bin mechanism employed by the parent
|
||
|
|
* class vtkPointLocator. vtkPointLocator allows for generic (zero and non-
|
||
|
|
* zero) tolerance point insertion as well as point location.
