- Impulse registered the FORM TDDD ("Three Dimensional Data Description") and
- it appears in the new Devices RKM. The format is basically tailored to
- store information pertinent to the Turbo Silver and Imagine rendering
- software, but since it is IFF you could add your own (inofficial) chunks to
- the file and keep it compatible with an existing standard. Exactly what IFF
- was created for. Not only that, but you would be able to draw on a store of
- existing 3D objects, and your own efforts might be usable in Imagine, too!
-
- The TDDD.doc is 11 pages long, so I can't give you much information about
- it. Suffice to say that it describes the geometry of a 3D world (objects
- especially) using points to build edges, and from these construct
- triangular faces. Attribute information includes color, reflectivity,
- transparency, and several others. I'm sure that extending these wouldn't
- be difficult.
- Your best bet might be to get the RKM:Devices (ISBN 0-201-56775-X)
- published by Addison-Wesley (#56775)
