The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Quickly setting up a 3D scene?
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.

Noob question: Between WebGL, OpenGL ES and emscripten, what is the recommended usage and relationship between them for creating an interactive browser based graphics app?
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.

Using Assimp library for commercial game development
Have you read the license? It's quite permissive. https://github.com/assimp/assimp/blob/master/LICENSE

What library would be good for loading .obj vertices, normals and texture coordinates?
I believe assimp is C. There is an example here.

I think I've managed to port my 2D/3D Engine to Linux [free download link in description]
I recommend checking out Assimp for model loading. What graphics API does it use and what did you use for the UI?

Deus Ex Machina engine first public repository commit! :D [+Talking about BOC state]
Thats is because to do internal test for load things I used blender (open source), but the professional world or at least seems that most of them still uses autodesk maya, and that is how last of 2021 came and final 3D models for the EA was ready to implement but Assimp have a open issude since 2018 relating problems to load animations with .fbx format if it was exported from maya ....

For your own engine, do you use an existing format or build your own managing meshes, materials etc in your scene?
You may be interested in the Open Asset Import Library. I recently replaced my own gltf import with this and it's been a real breeze, and a good reference for basing my own internal models on. Lots of supported file types and language ports.

Rotation problems when importing magicavoxel?
Check out ogt_vox.h by /u/jpaver which can read/write vox files.
-
VoxelEditor with the best OBJ Export?
If you can program you might be able to do this yourself using a library like ogt_vox to write out the resulting vox file, along with code like Assimp to import the geometry. If the vertices are all on a unit grid it should be relatively trivial to go through the quads (2xtriangles), calculate the face normal, and modify the voxel just below the quad with the texture sampled from the texture coordinates.

MagicaVoxel imported palette out of order
You might find looking at the implementation in ogt_vox.h useful, along with this discussion about the materials.
