Cut locus information


Geodesics on an ellipsoid (blue) from a single point (for flattening f = 110, latitude φ1 = −30°) form a segment of a circle of latitude; geodesic circles are shown in green and the cut locus in red.

In differential geometry, the cut locus of a point p on a manifold is the closure of the set of all other points on the manifold that are connected to p by two or more distinct shortest geodesics.[1] More generally, the cut locus of a closed set X on the manifold is the closure of the set of all other points on the manifold connected to X by two or more distinct shortest geodesics.
