MINIMUM DISTANCE BETWEEN TWO CURVES [message #20442]

Given:
a=f(x,y,z) and b=g(x,y,z), both a and b are separate curves. (Not straight
lines. Nor do they loop over themselves). f and g are unknown functions.
Only know g and f by some points in 3D space. Points are irregularly spaced.

Objective:
Find the minimum distance between a and b. Give the coordinate where this
minimum occurs in term of the nearest point on a and the nearest point on b.

Needs help:
Does anyone have a routine to do such calculation using IDL? Any other
suggestions appreciated.

Thanks in advance,
Mark Chan
