I mean really... just try a "trivial" case on your idea... Like *ANY* two points... It is obvious that the enclosing circle here would have a radius of 1/2 the distance between the two with the center at the midpoint of the line connecting them... Not, as you suggest, centered at either of them and a radius of the distance between them. I think you missed the point that the original poster was looking for the smallest enclosing circle, not an arbitrary enclosing circle. -Patrick ___________________________________________ | | | Internet: naughton@sun.soe.clarkson.edu | | BITNET: naughton@CLUTX.BITNET | | uucp: {rpics, gould}!clutx!naughton | |___________________________________________|
