 * The orthographic projection is an azimuthal perspective projection,
 * projecting the Earth's surface from an infinite distance to a plane.
 * It gives the illusion of a three-dimensional globe.
 *
 * Its disadvantage is that it fails to render the whole world in one view.
 * However, since the distortion is small at the center of the view, it is great
 * at rendering limited areas of the globe, or at showing the positions of areas
 * on the globe.
