Intractive Method for Scanning Three Dimensional Datasets

      Disclosed is an interactive method of scanning through a 3D
dataset, successively viewing slice by slice different parts of the
image in different directions.  Interaction by mouse clicking is
simplified without distracting users attention from the data being
viewed.

      For various reasons, it is often convenient to scan through a
3D dataset slice-by-slice, where the scan may involve moving through
any of the orthogonal (x, y, z) dimensions.  Note that the principle
of this disclosure is in no respect restricted to motion orthogonal
to any of the principal axes.

      The present conventional approach is to make a specific slice
selection, either by type-in or by means of an interactor such as a
scale bar or dial.  (See AVS* [Application Visualization System]  or
DX** [Data Explorer]).  Inevitably, such an approach distracts the
user's attention from the image of interest; this disclosure
overcomes that problem.

      Consider a stack of slices, one of which slices is being viewed
on the screen as a 2D image.  By way of example, a mouse-button click
in the upper half of the image moves the current slice up one
position towards the origin of the stack (slice:=slice-1).
Similarly, a click in the lower half moves the current slice one
position towards the bottom (slice:=slice+1).

      If the slicing is in one of the other orthogonal dimensions (x
or y), it might be more intuitive...
