RIB (.rib)


    RenderMan RIB user entity file.
    3D geometry format.
    Used for photorealistic modeling and rendering.
    Stores 3D object definitions and scene descriptions.
    Native format of the RenderMan application.
    RIB is an acronym for RenderMan Interface Bytestream.
    Developed by Pixar in 1990.

Import and Export

  • Import["file.rib"] imports a RIB file Graphics3D object.
  • Export["file.rib",expr] exports a Graphics3D expression to a RIB file.
  • Import["file.rib"] returns an expression of the form Graphics3D[ GraphicsComplex[vertices,primitives,opts]].
  • Import["file.rib",elem] imports the specified element from a RIB entity file.
  • Import["file.rib",{elem,suba,subb,}] imports a subelement.
  • Import["file.rib",{{elem1,elem2,}}] imports multiple elements.
  • The import format can be specified with Import["file","RIB"] or Import["file",{"RIB",elem,}].
  • Export["file.rib",expr,elem] creates a RIB entity file by treating expr as specifying element elem.
  • Export["file.rib",{expr1,expr2,},{{elem1,elem2,}}] treats each expri as specifying the corresponding elemi.
  • Export["file.rib",expr,opt1->val1,] exports expr with the specified option elements taken to have the specified values.
  • Export["file.rib",{elem1->expr1,elem2->expr2,},"Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
  • ImportString and ExportString support the RIB format.


  • General Import elements:
  • "Elements"list of elements and options available in this file
    "Rules"full list of rules for each element and option
    "Options"list of rules for options, properties, and settings
  • Data representation elements:
  • "Graphics3D"RIB user entity file represented as a Graphics3D object
    "GraphicsComplex"list of GraphicsComplex objects, each representing a 3D geometry stored in the file
    "PolygonData"polygon data in indexed form
    "PolygonObjects"list of Polygon primitives given in absolute coordinates
    "VertexColors"colors associated with each vertex, given as a list of color primitives
    "VertexData"list of vertex coordinates
    "VertexNormals"normal vectors corresponding to the vertices given by "VertexData"
  • Import and Export use the "Graphics3D" element by default for RIB files.
  • The "VertexData" element corresponds to the first argument of GraphicsComplex.
  • When rendering a RIB color model, Import automatically uses the setting Lighting->"Neutral".


  • General Import options:
  • BackgroundAutomaticwhat background color to use
    ImageSizeAutomaticoverall size of the graphics to display
    LightingAutomaticwhat simulated lighting to use in coloring 3D surfaces
  • Meta-information options:
  • "Comments"Nonelist of strings, representing user comments
    "CreationDate"Automatictime and date when the file was created, given as a string
    "Creator"Automaticapplication used to generate the file
    "Scene"Automaticscene name associated with the entity file
