assimp VS imgui-node-editor

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++.

Looks more like https://github.com/thedmd/imgui-node-editor/ to me - both are great libraries though.

I'm taking this low level node widget library: https://github.com/thedmd/imgui-node-editor

This sort of node graph?

It looks nice. If UI performance is a concern, one could move the GUI part to C++ and do some quick pybind11 Python bindings for better performance.

I've used this C++ ImGui node editor with similar features for some hacky synthesizer gui using this library: https://github.com/thedmd/imgui-node-editor

imgui-node-editor

Yes, I am looking for something like this https://github.com/thedmd/imgui-node-editor, but for C instead of C++
