OpenFlight (original) (raw)

OpenFlight (or .flt) is a 3d geometry model file format originally developed by Software Systems Inc. for its real-time 3d modeling package in 1988. Originally called Flight, the format was designed as a nonproprietary 3d model format for use by real-time 3d visual simulation image generators. The format was later renamed to OpenFlight to denote its nonproprietary image generation (IG) usage. The MultiGen modeling package (known now as Creator) and the OpenFlight format were rapidly adopted by the early commercial flight simulation industry in the later 1980s and early 1990s. NASA Ames was the first customer for the MultiGen modeling package.
