Sorry it took so long to approve your post. I didn't see it through the waves of spam comments we get here :) As for simplifying the longer edges, it's simply a case of testing the dot product of the line Vn -> Vn+1 with the line Vn -> Vn+2 (remembering to normalise them first). If they are the same, then the three vertices (Vn, Vn + 1, Vn + 2) are co-linear, and so you can remove Vn + 1 from the list. Thanks. Sorry it took so long to approve your post.

As a big fan of geometry I'm always amazed from the magic of Geometry. Thumbs up! Thanks for the informative post. As a big fan of geometry I’m always amazed from the magic of Geometry. Thumbs up!
