title: Creating a Delaunay Triangulation around Polygons
body: <p>It's possible to <a href="http://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.spatial.Delaunay.html" rel="nofollow noreferrer">create a Delaunay Triangulation in python</a> from a set of points, but how can I do the same for a set of polygons? For example, in the picture, I'd like to have the square be a kind of "obstacle", and generate the triangulation around that. I'd also like a way to know what the center point of each triangle is if possible.</p>
