Sample COLLADA files for development of an importer?

Question

Hi all,

I'm preparing to write a COLLADA importer in Java. There aren't any pre-written importers, and even if there were I would probably be picky, so I believe this is best. I am going with COLLADA 1.4 because I do not need the 1.5 features, and many programs don't yet support it. I found the spec for it and plan on following it, but it is much easier to follow by example and reference the spec for additional information.

So with all that... Can some of you who are experienced in COLLADA point me to some simple models that I can use to learn and test my importer as I write it? I will export a few with just geometry, but I need some with textures or materials, with skeletal and keyframe animation, etc. Any suggestions?

Alternatively, I know that Blender can export COLLADA 1.4 and it can import most formats. If you have a really good suggestion for a site that has simple 3D models in another format that I will just import and export as COLLADA, that would be fine too!

Thanks!

Answer 1

Okay I'm going to add an answer to my own question, because after writing this I've continued my searching and actually just found a very valuable resource.

The COLLADA Test Model Bank allows anonymous access and has numerous COLLADA files. It is located at collada.org, so it is official and I would expect all models to be correctly formatted.

I look forward to everyone else's answers as well.

Answer 2

I know two decent places at least:

• Thingiverse tag: 3D
• Google 3D Warehouse

The google site has lots of collada files, thingiverse has more in the way of stl (sterio lithography) files.
