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.
-
Scene organization
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.

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.

Issues with Assimp Loader and Bones
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
-
What is the best way to read .3DS files?
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
-
How can I retrieve normal scale and occlusion strength properties from GLTF 2.0 PBR materials using Assimp?
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.

A TRIANGLE!!! with OpenGL! Awesome right? 😅😜
Assimp is your friend

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

i wanna turn 3d models into a sprite and a normal map (the same way dead cells does it) Any library recommendations that i can use for this? Simpler and easier to learn the llibrarry the better as this is the only thing i am going to do with it.
There is probably some library more specific to your use case, but you can use assimp to load 3d models in C++.

Nanite-like LODs experiments
1) I used meshoptimizer to simplify meshes and building meshlets. But to combine these meshlets (for more efficient simplifying) I built a graph with weights and partition it. In this weight some metrics are included: the shared border length of a pair of meshlets, their facing direction and other similar metrics. The next step is to simplify these groups of meshlets (fixate borders for each of them and simplify meshlets within the group). So, you can make dependencies of newly generated meshlets on the initial ones.

Will the same texture used in many gltfs be duplicated in memory?
Here are some amazing tools for compressing GLTFs: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md

Maximum size of scene or a project in THREE.JS
I've also had good results with this tool: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md and kt2tdecoder + meshopt_decoder

[Part 7] Update of my Vulkan renderer: LODs, Multiple different meshes, Memory Allocator, Render architecture and more
Implemented Mesh LOD system. LOD selection is done completely on GPU. I generate LODs using meshoptimizer.
-
Given a mesh without indices, how I generate indices for that mesh and remove the duplicate vertices?
Maybe Meshoptimizer can be useful?
-
[Part 4] Update of my Vulkan toy renderer: Mesh Shader Pipeline, Reversed-Z Depth Buffer, SPIRV-Reflect and many more
Added NVidia mesh shader pipeline support, with old pipeline still supported on top. Meshlets are generated using meshoptimizer.
-
Algoritm to simplify geometric data similar to texture bitmapping
I've used the "Simplification" operation of meshoptimizer to simplify 3D model geometry: https://github.com/zeux/meshoptimizer
-
help implementing LOD edge collapse algorithm
I call meshopt_simplify(). It uses a quadric error metric based mesh simplification of some sort. I haven't really looked into the details of how it works, but the code (with some comments referencing papers) can be found here: https://github.com/zeux/meshoptimizer/blob/master/src/simplifier.cpp
