I have a set of points, all mixed up with no particular order of creation. If I run a little python script to draw a line using the points, I get a "messy" curve, like the drawing below.
I would like to know an approach to get only the boundary points to generate a curve which does not intersect itself... It is also not necessary to use all points.
I read something about it in http://forums.cgsociety.org/showthread.php?t=455797
but I still couldn't figure it out...
Thank you a lot
