"Heightfield" is a key term here. The idea is that you can assign different
depths to light and drak areas in a raster image. There are applications of
this that are very sophisticated. 4 in stance, Stereoplotting, where aerial
stereo-photographs are used as the database to make contour maps.

This is different than "Digitized" data for reverse engineering. It is
gathered by a co-ordinate measurement device. This yields "hard" data as
opposed to "soft" data that would need to be interperted in some way.

This is very related to robotic vision stuff...

   I do not know if it is true, but I imagine that there are
scientists who, by following the paths of the so-called 
"cold" intellect -possibly without being aware of it- are plumbing the
depths of a mystery rather than searching for the solution to a problem...
