Interpolation with Delaunay triangulation

Having a cloud point in the form of a distorted paraboloid, I would like to use Delaunay triangulation to interpolate points. I tried other methods (f.ex. splines) but could not provide the required behavior.

I was wondering if there is a quick way to use the results scipy.spatial.Delaunayin such a way that I can give the coordinates (x, y) and get the z-coordinate of the point on the simplex (triangle). From the documentation, it looks like I can get the simplex index, but I'm not sure how to get it from there.
