FBX (.fbx)

Background & Context

    • Filmbox file format.
    • ASCII or binary format.
    • Commonly used for storage and interchange of 3D assets.
    • Proprietary file format developed by Autodesk.
    • Represents a 3D object or collection of objects as a surface formed by a collection of primitives, including triangles, polygons and spline curves. Can also represent a full scene, including lighting, animation and camera information.
    • Optionally stores vertex normals, colors, textures and generalized shaders.

Import & Export

Notebook Interface

  • Save Selection As... exports the selected part of a notebook as a FBX file.

Import Elements

  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Summary"summary of the file
    "Rules"list of rules for all available elements
  • Data format representation elements:
  • "BinaryFormat"whether the file is a binary or ASCII FBX
    "Comments"comments
    "VertexData"list of vertex coordinates
    "PolygonData"the polygon elements in indexed form
    "UserExtensions"user-defined data associated with polygon vertices
  • Geometry representation elements:
  		• "BoundaryMeshRegion"boundary mesh representation of a solid
    "MeshRegion"mesh representation of a surface
    "Region"region representation of a surface
  • Graphics representation elements:
  • "Graphics3D"FBX file represented as a Graphics3D object
    "GraphicsComplex"FBX file as a GraphicsComplex object
    "PolygonObjects"list of polygon primitives given in absolute coordinates
  • Import and Export use the "MeshRegion" element by default for FBX files.

Options

  • Export option:
  • "BinaryFormat"Truewhether to write a binary or ASCII file

Export a 3D model to an ASCII FBX file:

Print the raw textual contents of the file:

Scope  (10)

Import  (4)

Import works on ASCII FBX files:

Binary FBX file:

Stream:

Import provides access to elements in the FBX file:

Export  (6)

Export works on 3D graphics:

Special regions:

Formula regions:

Import Elements  (10)

"BinaryFormat"  (1)

Test whether this file is a binary or ASCII STL:

"BoundaryMeshRegion"  (1)

Give a boundary mesh region:

"CoordinateTransform"  (1)

The coordinate system used by the FBX format is identical to the Wolfram Language:

"Graphics3D"  (1)

Give the Graphics3D object:

"GraphicsComplex"  (1)

Give the GraphicsComplex object:

"MeshRegion"  (1)

Give a mesh region:

"PolygonData"  (1)

Give the polygon elements in indexed form:

"PolygonObjects"  (1)

Give the list of Triangle primitives given in absolute coordinates:

"Summary"  (1)

Give the summary of properties:

"VertexData"  (1)

Give the vertex coordinates:

Export Options  (2)

By default, a binary file is generated when exporting:

Print the raw textual contents of the file:

Use "BinaryFormat"False to generate an ASCII file:
