What's in an FBX file

FBX files are normally saved in a binary format, but they can also be saved in an ASCII format. Here are the first few lines of a small ASCII-format FBX file:

; FBX ...

; ----------------------------------------------------

FBXHeaderExtension: {

    FBXHeaderVersion: 1003

    FBXVersion: 6000

    CurrentCameraResolution: {

        CameraName: "Model::Producer Perspective"

        CameraResolutionMode: "Window Size"

        CameraResolutionW: 1

        CameraResolutionH: 1

    }

    CreationTimeStamp: {

    ...

    }

}

;Object definitions

Definitions: {

    Count: 2

    ObjectType: "Model" {

    Count: 2

    }

}

Both kinds of FBX files use the .fbx filename extension. You can convert FBX files from binary to ASCII using FBX SDK, or you can use a utility program: see FBX Converter.

One way to get a feel for FBX is to view and a small FBX file in a 3D viewer, study the file in a text editor, and study the program that created the file or that processes it in some way.
