For anyone following along at home still, I believe I’ve found a fairly helpful answer on stack overflow.
Note that the solution is intended for actual points in a polygon, so if you intend to apply the method to a Shape2d object containing a series of Path2d objects, I recommend looking into (and using) the subdivide function in the Path2d object, as that will generate the actual points along the polygon, as opposed to the more abstract (but generally more useful) representation in the Path2d object.
If you don’t know what I mean or still have issues, feel free to put that in a response below.
Unfortunately, in my instance I believe I’ve run into a bug with getting Shape2d objects from Svg data in Cinder which I’ll be posting about, and linking to here once complete.
Cheers,
