/**

* @class vtkImageConnector
|
||
|
|
* @brief Create a binary image of a sphere.
|
||
|
|
*
|
||
|
|
* vtkImageConnector is a helper class for connectivity filters.
|
||
|
|
* It is not meant to be used directly.
|
||
|
|
* It implements a stack and breadth first search necessary for
|
||
|
|
* some connectivity filters. Filtered axes sets the dimensionality
|
||
|
|
* of the neighbor comparison, and
|
||
|
|
* cannot be more than three dimensions.
|
||
|
|
* As implemented, only voxels which share faces are considered
|
||
|
|
* neighbors.
