Geodesic

A geodesic is the shortest possible path between two points on a curved surface or space. Imagine stretching a rubber band tightly around a globe; the band follows a geodesic, which is the most direct route on that curved surface. On a sphere like Earth, geodesics are great circles (like the equator or a longitude line). In more complex spaces, geodesics are determined by the geometry’s rules, representing natural, shortest-distance routes without any unnecessary detours. Essentially, a geodesic is the straightest, most efficient line possible within the shape’s curved context.
