I'm also wondering if those edges Shapes are more or less quicker in term of calculation speed than a bunch of normal convex polygons.
That's what I was wondering too. I haven't seen anything yet which says either way.
Perhaps they'll answer your post :-)
Maybe it would be easier to think about a new helper method to transform or directly use blitzMax array instead.
Possibly... one which expects an array of coordinates. Something for me to ponder...
