FBX2glTF VS assimp

I've recently done this but not fbx only, was textures and some other asset files. Converted the model to gltf and then loaded it in for an augmented reality app. Just be cautious on load times. I had to compress it using this https://github.com/facebookincubator/FBX2glTF

i use maya to make blendshapes in FBX format then use https://github.com/facebookincubator/FBX2glTF to make the gltf and https://meshoptimizer.org/gltf/ to make the GLB

FBX can be converted to GLTF via this tool https://github.com/facebookincubator/FBX2glTF After convertation import GLTF as usual file

Using this tool (https://github.com/facebookincubator/FBX2glTF) FBX2glTF-linux-x64 on the POLYGON MINI characters I get this output

I found the https://github.com/facebookincubator/FBX2glTF project invaluable as a resource for seeing how to get useful information out of FBX.

I'm using the FBX2glTF found here and this is what I'm getting before the orientation fix;

If you use something like libassimp https://github.com/assimp/assimp it will allow you to import these and access the data to generate your Vertex Array Objects then render to a frame buffer object.

If you just want to load other data in a relatively simple fashion, assimp https://www.assimp.org supports loading a bunch of different formats and is pretty easy to use.

The emscripten interface for the assimp library. It runs entirely in the browser, and allows you to import 40+ 3D file formats and access the result in JSON or glTF format. This is not a full port of assimp, but an easy to use interface to access it's functionality.

I ran into what sounds like a similar problem a few months ago. It turns out this was an assimp bug: https://github.com/assimp/assimp/issues/1974

You could give assimp a go (there is a python version) i've used it for 3DS before then you can export to something else. https://github.com/assimp/assimp/blob/master/port/PyAssimp/README.md

I have checked the source code for GLTF for this and it is not handled by Assimp. I created an issue as in their Github.

Assimp is your friend

Have you read the license? It's quite permissive. https://github.com/assimp/assimp/blob/master/LICENSE

There is probably some library more specific to your use case, but you can use assimp to load 3d models in C++.
