Editing Vertices in a Mesh/Sphere

        v.x += sy * sz * deform;
        v.y += sx * sz * deform;
        v.z += sx * sy * deform;
        v *= float(rad);
        vertices.setVertex(i,v);
    }

if i run this code in an actual Version of openFrameWorks, i still see an unmodified sphere. Can Anyone help please? How to properly edit the Vertex of a sphere?
