Another freebie, actually pretty good:
August 17, 2012 – FlightGear v2.8.0 is Released
The FlightGear development team is happy to announce the v2.8.0 release of FlightGear, the free, open-source flight simulator. This new version contains many exciting new features, enhancements and bugfixes.
V2.8.0 includes improvements making FlightGear world more realistic than ever before. Placement of random buildings and trees match the underlying terrain texture, and urban areas now have denser random buildings. Textures can be region specific, and users can select between summer and winter textures in-sim. An improved atmospheric scattering and terrain haze model means the lighting of the terrain is more realistic. Finally, a new automated system is now available for scenery submissions that automatically get rolled into the scenery distribution to be enjoyed by everyone.
A very exciting new addition is “Project Rembrandt”. This is still considered experimental and not enabled by default. This enables real-time shadows, and support for multiple light sources such as landing lights. Even rotating beacons illuminate the surroundings correctly.
Founded in 1997, FlightGear celebrated the 15th anniversary of it’s first official release in July. FlightGear is developed by a worldwide group of volunteers, brought together by a shared ambition to create the most realistic flight simulator possible that is free to use, modify and distribute. FlightGear is used all over the world by desktop flight simulator enthusiasts, for University research and education, for a variety of aerospace engineering and visualization work in industry, and even for interactive exhibits in museums.
FlightGear features more than 400 aircraft, a worldwide seamless scenery database, a multi-player environment, detailed sky modelling, a flexible and open aircraft modelling system, varied networking options, multiple display support, a powerful scripting language, and an open architecture. Best of all, being open-source, the simulator is owned by the community and everyone is encouraged to contribute.
