Cal3D files importer (.cmf, .csf...)

[Somwonere]

Cal3D is an open source model format that nobody has made a (good) importer for.

A 3DS game uses them and i'm trying to rip the models.

I would love a Noesis plugin and i also included the demo. cal3ddemo.zip

I found a noesis plugin on the XeNTaX archive for that, (link) but only the skeleton (fmt_csf.py) works (screenshot)

List of Cal3D files:

• .cmf (Mesh)
• .csf (Skeleton)
• .crf (Material)
• .caf (Animation)
• .cpf (Morph Animation)
• .cfg (Model Configuration, probably exclusive to demo)
• .xmf (XML, Mesh)
• .xsf (XML, Skeleton)
• .xrf (XML, Material)
• .xaf (XML, Animation)
• .xpf (XML, Morph Animation)

• Cal3D on Github
• Format Documentation

Maybe because Cal3D is assumed to be dead?

Yes it's dead.

My programs support the following Cal3D file formats:

• cal3D ASCII Mesh *.XMF
• cal3D Binary Mesh *.CMF
• cal3D Binary Mesh (IMVU) *.XMF
   

 

- 3D Object Converter (Windows);

- 3D Object Converter (AmigaOS)

- i3DConverter x64 macOS

- i3DConverter amd64|x64 Linux

Good luck.

Well, first I've to admit I don't like the mesh format, so I'm biased.

I don't understand the logic how vertex blocks are built in cally_head.cmf.

After getting a stop condition assembling the vertices was not too hard but I didn't get the face indices applied.

So I used meshlab for building the mesh.

I’d make one if this format was actually used somewhere

Content Creation Platforms: Platforms like the virtual world IMVU and the filmmaking software Moviestorm use the Cal3D system for their models and animation files.

Specific Software: Various specific projects and tools have integrated Cal3D, including:

• A Tale in the Desert (MMORPG)
• The Nebula Device (3D engine)
• ReplicantBody (character animation toolkit)
• HALCA (a real-time character engine used in the XVR virtual reality system) 

edit: if you thought (like me) to get some models for free after having installed ATaleInTheDesert: forget about it!

It's a subscription based game.

Oh, my bad should have backread. I’ll make it when I’ll have some more time, if i do ill definitely link it here

I also noticed that the file spec linked above for .cmf files is different to the samples provided, i.e. the samples are earlier versions of the format and don't match the spec exactly.  Some of the samples are versions 700 and 1100.
