.RIB File

The rib file extension is used for a Renderman Interface Bytestream 3D graphics format. Format probably developed by PIXAR.

A rib file consists of ASCII RenderMan language commands in use for 1) transporting a complete scene and frame description to a RenderMan-compliant renderer, or for 2) storing resources. It is not commonly used for moving objects between 3D applications.

RenderMan at its inception over a decade ago was hailed as "the 3D PostScript," and the comparison is still apt.

One a "scene description" and the other a "page description" language, both RenderMan and PostScript literally program their target devices--a 3D renderer or 2D printer, and the user won't see a .rib or .ps file if commands are sent directly to the device.

However, "encapsulated" PostScript (*.ai and *.eps) files are widely employed for graphics interchange, while the RenderMan equivalent--the RIB entity file, has little support.
