extract geometry for structured points
vtkImageDataGeometryFilter is a filter that extracts geometry from a structured points dataset. By specifying appropriate i-j-k indices (via the "Extent" instance variable), it is possible to extract a point, a line, a plane (i.e., image), or a "volume" from dataset. (Since the output is of type polydata, the volume is actually a (n x m x o) region of points.)
The extent specification is zero-offset. That is, the first k-plane in a 50x50x50 volume is given by (0,49, 0,49, 0,0).
