We introduce the concept of couple points as a global feature of surfaces. Couple points are pairs of points $({\mathbf x}_1,{\mathbf x}_2)$ on a surface with the property that the vector ${\mathbf x}_2 - {\mathbf x}_1$ is parallel to the surface normals both at ${\mathbf x}_1$ and ${\mathbf x}_2$. In order to detect and classify them, we use higher order local feature detection methods, namely a Morse theoretic approach on a 4D scalar field. We apply couple points to a number of problems in Computer Graphics: the detection of maximal and minimal distances of surfaces, a fast approximation of the shortest geodesic path between two surface points, and the creation of stabilizing connections of a surface.
