Oct 27, 2007· It is, as the illustration shows. So depending on where V is, there can be either one or two geodesics. The key to finding the dividing lines between the 1-geodesic and 2-geodesic regions is to realize that a straight line from an image of F must stay completely within the unrolled cone. This restricts the 2-geodesic region to the area reachable from both images of F.
