stu96art has asked for the
wisdom of the Perl Monks concerning the following question:
Thanks for everyone's help on my "Inside??" question, but I think that it would be easier to be able to tell if an order of points is going clockwise or counter-clockwise. My problem is that I have points on the line and a command that I use (in the final output) that will connect two points with an arc. What I need to do is make sure the arc curves inside (making an notch, not a tab-curving outward). I can do this if I can order my points in a clockwise fashion. Once again, thanks for all the help with the Inside?? problem, but if you could help me with finding out how to order the points in a clockwise manner. Thanks.
