...A simulation developer can use OpenFrames to specify what they want to visualize, without having to know any details of computer graphics programming.
OpenFrames is currently used by three NASA programs: Copernicus (NASA JSC), the General Mission Analysis Tool (GMAT, NASA GSFC), and a VirtualReality exploration tool (NASA GSFC).
...It was designed particularly for the needs of videogames, but the library is usable for non-game tasks, such as any other type of applications (rendering/visualisation/virtualreality) and tools.
