The Unofficial 3DStudio 3DS File Format

V1.0 By Jeff Lewis (werewolf@worldgate.com)

Notice

This document is an attempt to document the AutoDesk 3DS file format. This was made difficult in that I don't own or have access to a copy of the program, only to sample files. Fortunately, someone used AutoDesk's own 3DS file development kit to create a program which dumps the contents of a 3DS file into a human readable form - albeit somewhat inaccurately. The codes listed and their names come from that program and have been confirmed by testing.

It should be known that the 3DS format is, as far as I know, a proprietary format of AutoDesk and that the format details are not widely known or are protected by AutoDesk.

It is not my intent to infringe on AutoDesk's rights, but simply to make a large collection of 3D image files accessable to people who do not use 3D Studio - or cannot use it because AutoDesk has not chosen to provide a version of 3D Studio for the computer they use (ie: The Macintosh in my case).

Warning

This document is not intended to be a definitive definition of the 3DS format and is not authorised by AutoDesk. While every effort has been made to ensure its accuracy, or at least warn you when there's doubt about its accuracy, no guarantee of accuracy in any of it can be given. Use this document at your own risk.

Document layout and format information

In the following document, chunk names which are in bold mean the chunk format has been determined with certainty. Chunk names which are not bold but have a struct following means that this is a guess but is not substantiated. All others are unknown.

A short is always a two byte integer.
A long is always a four byte integer.
A float is always a four byte IEEE floating point number.
A cstr is a zero byte terminated ASCII string without a length.
A char is a single byte integer.

3DS File Format

A 3DS file consists of blocks of data called chunks. Every chunk starts the same way:

• short chunk_id;
• long chunk_len;

The chunk_id is a unique code which identifies the type of data in this chunk and also may indicate the existence of subordinate chunks. The chunk_len indicates the length of following data to be associated with this chunk. Note, this may contain more data than just this chunk. If the length of data is greater than that needed to fill in the information for the chunk, additional subordinate chunks are attached to this chunk immediately following any data needed for this chunk, and should be parsed out. These subordinate chunks may themselves contain subordinate chunks.

Unfortunately, there is no indication of the length of data which is owned by the current chunk, only the total length of data attached to the chunk, which means that the only way to parse out subordinate chunks is to know the exact format of the owning chunk. On the other hand, if a chunk is unknown, the parsing program can skip the entire chunk and subordinate chunks in one jump.

In the following list, I try when possible to indicate that a chunk is likely to have subordinate chunks and what kinds of subordinate chunks I've seen attached to it.

Another problem lies in cstr names. I've seen cases where the space used by a name is riddled with fragments of old names. It seems that the space reserved for a name is not cleared if a smaller name replaces it. If the name is removed, you'll get a zero byte indicating an immediate end of string, followed by an undetermined number of characters and nulls. This seems to happen only when the cstr is at the end of a block of data and so you can assume that the length of the chunk contains no other subchunks. See viewport_data for an example of this.
