Very extensive list ! I also propose AMF (http://en.wikipedia.org/wiki/Additive_Manufacturing_File_Format) loader. (3d file format used for 3d printing). I already have the basics of the loader done, so I could modify it a bit and add to the examples.
Most of these loaders are more important for special cases such as an editor, because for let's say games it might be better to convert into the three.js format straight away, right? In these cases the converters/exporters are more important.
We've tested glTF as a replacement for three's formats as an optimization - there the data is binary and can be compressed with geom compression.

@kaosat-dev Added to the list! @Herst Yes. It's mostly for editors or apps that don't require fast load times.
I am also looking for a IGES loader. I would even maybe start building one myself but not sure where to start.
About 3DS Loader :
Hi everyone, long time ago, I needed to make a 3DS loader for 3DzzD Web 3D engine, that was a little hard to do... not difficult to obtain some first results but rather to handle all the chunks correctly, but after some times I managed to produce a pretty efficient loader. the 3DS file format spécifications are difficult to find, but I finished to find one that worked pretty well. I 've built the loader for 3DzzD with this documentation and it works even better than the one in the current photoshop (better handle on pivot/smooth groups/scale/ keyframe/etc...), so here is the spécifications I have used (3DzzD source code is opensource and may help but code is really ugly... a ten years old project...)

About OBJ Loader :
I modified the current OBJ loader and get about at least 10/15 FPS more on a lot of 3d models, but for now I did not found how I should do to post these changes ?
The problème was mainly due to the fact that the current OBJ loader create too many objects (more than the original 3d model, one object created at each material change) and also the 3dFaces with same material was not groupped together even within the same object, and was producing too many WebGL calls

Thanks! Added to the first post.

Oh! Interesting. You mean the OBJMTLLoader one though. Right?
Oh! Interesting. You mean the OBJMTLLoader one though. Right?
Yes,, to be more precise the "if ( /^usemtl /.test( line ) ) " block create a new object/mesh for each material switch, this ends with poor performance and a wrong objects hierarchy.
I will post a simple test case showing the difference between both the current loader and the one modified (difference is mainly noticeable on mobile device)
Here is the test case for the current loader and the one optimised :
http://demo.dzzd.fr/threejs/OBJMTLLoaderTest/
EDIT: I got 10 FPS on GalaxyTab3 with the current loader and more than 60 FPS with the new one, difference may be hard to see on fast devices
PS: If you wonder where the 3D model comme from :)
Does anyone know about IGES. I could really use an IGES loader. If someone could just point me in a direction to start on how to build one? Or if there is one out there somewhere. I noticed the folks at http://www.3dfile.io/ and some of the other 3D visualization sites are using ThreeJS and allowing for IGES uploads.
K3D.js (MIT license) has a parser for OBJ, 3DS, MD2 and Collada. http://k3d.ivank.net. See #3843.
I really hope for the .m2 models, its a huge community arround. I would offer my help with model files etc. you can contact me for that case on skype: deexone . As hint from one lib developer http://bridge.net/ could be maybe used to transform his lib to js.
Hey I have a BVH loader that parses through a BVH file and outputs a THREE.Skeleton and AnimationClip for easy use with the Mixer: https://github.com/herzig/BVHImporter and the working example: http://herzig.github.io/BVHImporter/ It's mainly tested on the CMU BVH files and some others.
Are there any guidelines on how the loader API should look like?
@herzig Sweet! A BVHLoader would be awesome! Loaders basically have a .load() and .parse(). You can use MD2Loader as reference, but I would be happy to clean up your code if you do a PR with what you have now (an example + sample animation would be much appreciated too).
Hi there, just to sync this list with files loader in the repo...
3MFLoader is missing in the list but already implemented. BinaryLoader is missing in the list but already implemented. DDSLoader is missing in the list but already implemented. FBXLoader is unchecked but already implemented. HDRCubeTextureLoader is missing in the list but already implemented. MD2Loader is unchecked but already implemented. NRRDLoader is unchecked but already implemented. PCDLLoader is missing in the list but already implemented. PlayCanvasLoader is missing in the list but already implemented. RGBLLoader is missing in the list but already implemented. SVGLoader is unchecked but already implemented. TGALoader is missing in the list but already implemented. TTFLoader is missing in the list but already implemented.
next:
ASCLoader should be added to the list, and PR will be send in few days. LASLoader should be added to the list, and PR will be send in few days. XYZLoader should be added to the list, and PR will be send in few days.
Best regards, Tristan
OpenCTM might be a good addition, since Autodesk is using it for their cloud service https://en.m.wikipedia.org/wiki/OpenCTM

I'm working with some iOS devs in the AR space, might there be a loader for the binary SCN files used by Apple in ARKit? I'm working on making use of the BinaryLoader and we'll see if I can get that working.
@mrdoob Sorry I'm so late. NIfTI is a NMR data format which transferred from DICOM. My current solution is get a 3D shape from it as VTK/OBJ format.
How about IFC loader. This format is using very common in construction for its 3d model
@mrdoob what are the guidelines + knowledge prerequisites to build a three.js loader ? I want to build one, but it want to be sure to make it the right way. Thanks
