OOF documentation where?

Post by Diedel »

The one on descent-network.com might be outdated. I need a current version.

Thought I already posted this...DBB must have swallowed it up...lol :D

This is from OOF Editor and is in VB. Lemme know if you can follow it. This is from D3, might be differences to D2.

Code: Select all

***** OOF File Format *****

The beginning of every OOF file has a File Header which contains
the file ID and version number of the OOF. After that is a series
if chunks that each begin with a Chunk Header describing the type
of chunk.

Ofc I can follow - thx very much! :D

(Geez, these guys are really pushing me into adding hires models ... :roll: )

Of course we are! It will be the coolest thing since you started the project. :mrgreen:

Look around the D3 development section at PD, some of the OOF tools are opensource. (If you do not have enough info already)

Whee! Thanks for appearing SS! I'd been looking for you to get that which you just posted. :P

We love you Deidel. :D

OOFs in D2!!! YAY!
Who's going to head up the D3 models to D2 project? :P

Let's see...

[x] Better Dynamic Lighting
[x] Particle systems
[x] High-res Textures (NovacroN's Descent Relived)
[x] Better polymodel format (oof)
[ ] OOF Higher-poly models of all D2 and D2: Vertigo Robots.
[ ] High-res robot textures to complement said models and the new level textures.

Looks like we need to find a couple project captains... :P

I would volunteer, but I can't do crap with either a 3D modeler or a photo editor...

I'll model some higher-poly ships if you want (and I get time)! PM me about it...

There's still a lot of work to. First I've got to get oof model rendering to work. And it's another story to have complex robots with moving parts. I am not a math expert, I have to read that matrix and vector stuff everytime again I need it.

Yay!! :D Take as much time as you need to get it right.

I can't model either or I would volunteer. :(
Might I recommend using a system like the Freespace Upgrade for Freespace2 at Hard Light Productions? This would allow multiple modellers to remain coordinated.

iirc the descent network still has a repository of descent 2 robot models that somone did in truespace. they are slightly better than the originals but they would probibly require some work for compatability. might be worth looking into.
