This allows optional creation of geodesic lines, which represent the shortest distance between the points based on the ellipsoid.
When geodesic mode is used, it is possible to split the created lines at the antimeridian (±180 degrees longitude), which can improve rendering of the lines. Additionally, the distance between vertices can be specified. A smaller distance results in a denser, more accurate line.
