Caligari trueSpace is a 3D art and animation program, now discontinued, from a company that was bought out by Microsoft. Its files are of two basic categories: objects and scenes. Each comes in two format varieties, ASCII and binary. The file extensions (.cob and .scn) distinguish the objects and scenes, but do not indicate whether the files are text or binary; this requires inspecting the contents. The Wikidata and PRONOM IDs shown in the infobox are for the ASCII and binary versions in that order.
