ROFF

ROFF (sometimes construed as Raven Object File Format, but actually stands for Rotation, Origin File Format, or perhaps Rotation Object File Format) is a 3D animation file format used by the Ghoul 2 game engine from Raven Software, alongside the GLA format. It may be found in such games as Star Wars Jedi Knight: Jedi Academy.
