Kick ass Matt great to hear form you.
I believe that the linear Algebra Class in Numpy can get that done as long as you feed in the right matrix. I guess I don;t know how to get a covariance matrix from a mesh. It think it is something like gettinng the centroid of an object. Those libraries are great is there an easy way to call them from Python that you know ?
