------------- The problem: Find a nice formula for the distance between arbitrary circles in 3 dimensions. The circles can be in any orientation relative to one another. The distance is defined to be the minimum distance between any two points on the circles. The circles could intersect, for instance. I hesitate to submit this because I wanted to do it myself. I don't know if there IS is a nice formula! Maybe I'll figure it out before anyone sends the answer... Charlie Perkins, IBM T.J.

When you say "points on the circle" do you mean points on the perimeter? Under certain orientations, interior points will provide the minimum distance.

------------- By circle I meant a "hoola-hoop" -- NOT a disk (or frisbee). A "circular line". -- Charlie Perkins, IBM T.J. Watson Research philabs!polaris!charliep, perk%YKTVMX.BITNET@berkeley, perk.yktvmx.ibm@csnet-relay
