// .NAME vtkImageConnector - Create a binary image of a sphere.
|
|
// .SECTION Description
|
|
// 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.
