Type of format3D file formats

The early advantage OpenFlight held over many 3d geometry model file formats (.obj, .dxf, .3ds) was its specific real-time 3d graphics industry design.[citation needed] 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, such as Wavefront Technologies, or Alias Systems Corporation[citation needed], tried to focus more on visual aesthetics for non-real-time based rendering graphics packages.

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[citation needed], and is currently administrated by Presagis.

Associated File Formats

OpenFlight models can have several associated files in different formats, that define elements such as material characteristics or shaders.

Modeling Tools

There are several modeling tools currently on the market that both read and write the OpenFlight file format. The standard bearer of the file format Presagis Creator offers the widest compatibility with the file format. Another modeling tool using OpenFlight as its native format in Remo 3D[2] from Remograph. Blender previously had integrated support for importing models in OpenFlight format. However, it appears as though this functionality has been abandoned in newer versions and there is currently no support for exporting to this format.[3] Autodesk 3DS Max still supports exporting to OpenFlight format as of the 2024 version of their software.[4]

Vendor specific alterations

Because the OpenFlight file format allows for vendor specific data field additions, some modeling and simulation tools might not fully support vendor specific additions to the file format.
