OpenFlight
OpenFlight〔(【引用サイトリンク】title=OpenFlight Standard )〕 (or .flt) is a 3d geometry model file format originally developed by Software Systems Inc. for its MultiGen〔(【引用サイトリンク】title=Multigen-Paradigm 25th Anniversary )〕 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〔(【引用サイトリンク】title=Creator - 3D Modeling Software )〕) and the OpenFlight format were rapidly adopted by the early commercial flight simulation industry in the later 80's and early 90's. NASA Ames was the first customer for the MultiGen modeling package.
The early advantage OpenFlight held over many 3d geometry model file formats (.obj, .dxf, .3ds) was its specific real-time 3d graphics industry design. This means that the format is polygon based (rather than NURB surfaces), and provides a real-time tree structure essential for real-time IG systems. Most early graphics file formats worried more about visual esthetics for non-real-time based rendering graphics packages such as Wavefront Technologies, or Alias Systems Corporation.
The OpenFlight file format is still widely used today in the high end real-time visual simulation industry as the standard interchange format between different IG systems, and is currently administrated by Presagis.
