:-) Ah sorry, I aimed my response toward doing as much in POV-Ray as 
possible given you seemed averse to intersecting the shapes with solid 
pigments and using a stand-alone edge detection program.

To just try the -render perspective camera above, below and combine 
idea- do one set of frames with the camera above and stick those frames 
in a directory aboveFramesDir and similarly a camera below scan.

You're already using your own image->df3 program. Read in both above 
frame and below frame images and take the max r,g,b found before you 
write the df3 sample position. If the method works, refinements in 
position etc, can wait until you find you need them. Might be the basic 
idea doesn't work for some reason I don't see(1)...

(1) - There are issues where any scan approach will run into 
complications beyond those being considered presently. Interior textures 
different than outside textures for objects scanned, for example.
