Shouldn't your definition for the taxicab distance (dT) be written
Quote:
dT(A, B) = |AX - BX| + |AY - BY| + |AZ - BZ| + ...
And with Rob's hints, I think I figured out your "segment" formula:
Quote:
A segment = {P | dT(P, A) + dT(P, B) = dT(A, B)}
If I indeed understand it correctly, a "segment" turns out to be all points on or within a rectangle* with points A and B at opposite corners.

*Or a rectangular prism in three dimensions, or a rectangular hyper-prism in more than three.
