In this ongoing work we present a method to associate to an object a set of spheres representing its shape (skeleton and thickness) and orientation. The notion of direction is defined with spheres and mereotopological relations. The study of the relative position of two directions leads to the notion of angle. We completely survey the case of shape representation of 2D convex objects, and propose a construction algorithm.
