			FSX introduced a three-dimensional ''geoid'', again based on a local origin, (reasonably relative-to-user),
	<br>		<br>
	~~This was termed~~ '~~round earth~~' ~~in the marketing material and introduced some issues with scenery design~~.		which then renders curvature of the earth, subsequently displaying a 'relatively-true' horizon.

			The geoid representation/implementation is supposedly optimized for the simulator's primary-market's population-centres, (with a quad-tree optimzed for 1:1 aspect ratio @ 45* latitude).

			It is unknown/untested/unpublished just how accurately the FSX geoid addresses various IRL aspects

			e.g. ''equatorial-bulge'', (i.e. the gravitometric anomalies which affect local MSL, and subsequent in-simulation mapped elevations),
