OFF (Object File Format) is a scene description language originally developed by Randi J. Rost at Digital Equipment Corporation's Workstations Systems Engineering.

Format

There is both a binary (.off), and a text (.aoff) version of the format.

An OFF "file" can actually be a collection of files, consisting of a main .off or .aoff file, and other files referenced by it. The conventional filename extensions for these other files are .geom, .bgeom, .pcol, .bpcol, .vcol, .bpcol, .vcol, .bvcol, .ipcol, .bipcol, .ivcol, .bivcol, .pnorm, .bpnorm, .vnorm, and .bvnorm.

Identification

An .aoff file has lines that begin with keywords such as "name", "author", "description", "type", "geometry", etc.
