* @class vtkImageToPoints
|
|
* @brief Extract all image voxels as points.
|
|
*
|
|
* This filter takes an input image and an optional stencil, and creates
|
|
* a vtkPolyData that contains the points and the point attributes but no
|
|
* cells. If a stencil is provided, only the points inside the stencil
|
|
* are included.
|
|
* @par Thanks:
|
|
* Thanks to David Gobbi, Calgary Image Processing and Analysis Centre,
|
|
* University of Calgary, for providing this class.
