RIB (.rib)

Import and Export support Version 1.1 of the RIB entity file format.
Import reads planar convex polygon data from RIB entity files, ignoring possible directives for geometric transformations.

Background & Context

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,sub_a,sub_b,…}] 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 expr_i as specifying the corresponding elem_i.
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.

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 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:
Background Automatic what background color to use

ImageSize Automatic overall size of the graphics to display

Lighting Automatic what simulated lighting to use in coloring 3D surfaces
Meta-information options:
"Comments" None list of strings, representing user comments

"CreationDate" Automatic time and date when the file was created, given as a string

"Creator" Automatic application used to generate the file

"Scene" Automatic scene name associated with the entity file
