I am trying to create a polygon in VB6 using the polygon function.

I have many points in random order that I would like to create the polygon with.

Unfortunately, the order is important when developing a polygon, as i get a jagged looking polygon, as opposed to a nice closed polygon.

I was wondering if anyone had any good ideas/tricks to develop an algorithm that can go through these points and put them in an appropriate order.

Thanks so much!

I used the Graham Scan Algorithm to actually go ahead and solve this problem.

If you follow the pseudocode, be careful.

The line

while ccw(points[M-1], points[M], points[i]) <= 0:

Should be

while ccw(points[M-1], points[M], points[i]) >= 0:
