New model format

[revanic]

Here I have attached a zip containing the files needed for loading and drawing MDO's in Q3. Everything needed is in tr_model_mdo.c, including the loading and tag finding. The only thing you need to do is add the remaining code yourself ( such as the registration, MOD_MDO, SF_MDO, etc ). I'll be uploading the blender exporter soon. There is just a bit of trouble I am having with the auto positioning.

Edit: Decided to upload the blender exporter " as is " for now. It's in beta I guess. Tags require specific rotations to face forward, you'll have to figure out which way to rotate the tag bones on your own. Don't use auto position for either the floor or origin, they don't work as intended.

A "Derigify" checkbox like the IQM exporter could be useful, having it export only DEF- prefixed bones


Also I've committe dthe code so far into the openarena/engine git

I undertand that MDO will not be feasible for public usage before a new OpenArena version will be released (years, probably)... however when you will want to create a page about it in OA wiki, feel free to ask me if you need help (but I can guess someone with your programming skills does not require any help for using a wiki! :-)).

By the way, what about proposing the new standard also to ioquake3 guys?

[revanic]

I don't think the IOQ3 guys would want just another version of MD4. IQM bests MDO if only because it can support true skeletal deformation if anyone bothered, though MDO can be expanded to include such abilities. LODs inside the model format itself is pretty advantageous though. Maybe.

Another thing that may be noticed is that the Matrix3x4Lerp I included has a "SLERP" option. It's not a true SLERP, but does re-normalize the matrix to undo any squashing that happens while lerping. This can be useful for preventing "Tiny limb syndrome", but can be turned off by setting the final parameter in the function to qfalse ( of course ). Could create a cvar for it if desired.

As for now, I will try to work on that de-rigify option.

Fromhell: I just looked into the Git, careful with trying to check ident in RegisterMDO. It uses straight chars like IQM( I don't know why I really did that ) so you can't check it as an int. should leave it as

Code:

loaded = R_LoadMDO(mod, buf.u, filesize, name);

without the ident check.

The engine still doesn't render MDOs after I changed that also.


i hope to have something someday. This is the crap i'm dealing with in an MDR pipeline

[revanic]

I'm gonna go ahead and check your code in the repository, however MDO's not loading may have something to do with rigify ( which I have yet to do a de-rigify option due to laziness and not wanting to do too much after finally getting something to work, just yet. )
