Grand Prix Legends .3DO File Format by P.A.Flack 1999
>> INCOMPLETE! (but getting there...) <<
last revised 7/June1999
07/June/99: More information on the Tracks section (almost finished !)
24/May/99: Complete reorganisation; new animation :-)
The 3DO files are the most complex I've seen as they consist of several sections which are linked together.  At the start of a 3DO file is a header of the standard sort (see the main page).  This header serves simply to show how big the rest of the file is.

The various sections that make up the 3DO file are now listed, but not in the order they appear in the file.  Not all sections always appear either, and the header doesn't seem to offer any clue as to which sections do exist.  The only way to find out is to read each section in turn, and find out what sort it is by looking at the section header (standard sort).

The structure of this page has been reorganised as follows:

Vertices, Planes, Normals and Strings
Primitives
Handles
General 3DOs - a sort of tutorial, which doesn't quite fit in with the rest of these pages...
Tracks
Cars

If you find any mistakes or new information then I'd like to know - you'll get credited for it.
If you re-post this somewhere, don't do it in pieces as it wouldn't mean much then...
If you use this or repost it, credit me so I know how useful it has been :-)
