Earthview is an orbital rendering engine for FlightGear designed to get credible visuals when using spacecraft such as [[Vostok-1]]. It is based on projecting a simple textured sphere representing Earth into the scene using ray optics. Since there is only a single object in the field of view, performance is generally very good provided that there is enough texture memory available.

A long standing problem in FlightGear's atmosphere definition has now been addressed and JSBSim spacecraft should now be able to reach any orbital altitude within their capabilities (previously flight was restricted to be below 150 km altitude).

Thorsten remarked that a good way to see the blue planet from high up was to start FG using the ufo at a high altitude (around 10 million ft is quite good with the texture resolution provided), open the GUI from the View menu, push start, wait for the textures to load and admire the view.
