I have for this purpose, in my case a bacteria carpet in 3D, applied
a from me so-called "blanket" transformation:
A 2D image is generated where each pixel is assigned the maximum
stack number (Z-coordinate) of the binarized 3D-data set.
Unluckily I did that in IDL since I was not able to do it in ImageJ.
Perhaps there are ImageJ gurus with a solution in ImageJ. The result
is something like an umbra, if you are familiar with morphologie
mathématique, or a distance map where each pixel represents the
distance from the base in multiples of the Z step size. I have called
it blanket, since it is similar to let fall a very flexible blanket
over your 3D-object.
