1. A method for modeling a world database that is a spheroid in a computer graphics simulation system, comprising the steps of: modeling the world database using a plurality of geodetic terrain gridposts; creating a triangulated network mesh based on the geodetic terrain gridposts in real-time as a function of eye position and the triangulated network mesh is stored in geodetic coordinates; converting the triangulated network mesh from geodetic coordinates to Cartesian coordinates including multiplying a longitude portion of the geodetic coordinates by a latitude-dependent scale factor to obtain a Cartesian coordinate; rendering the triangulated network mesh using geometry formed by the triangulated network mesh to form an image displayable to a user; and reducing a terrain facet size of the triangulated network mesh as the latitude increases.
