* @class vtkOctreeImageToPointSetFilter
* @brief Convert an octree image to point set
*
* vtkOctreeImageToPointSetFilter is a filter that converts an image with an octree unsigned char
* cell array to a pointset. Each bit of the unsigned char indicates if the cell had a point close
* to one of its 8 corners.
*
* It can optionally also output a point data array based on an input cell data scalar array by
* setting SetInputArrayToProcess. This array will have one of the components of the input array.
*
* @warning
* This class has been threaded with vtkSMPTools. Using TBB or other
* non-sequential type (set in the CMake variable
* VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
*
