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.

Confused in terms of where to start with framework/technology etc. Need help picking between learning ShaderToy v/s OpenGL v/s WebGL
If you want to go all the way, https://learnopengl.com/ is a favorite around here. You could build a glTF viewer from scratch starting from that tutorial and https://github.com/jkuhlmann/cgltf and eventually building towards https://google.github.io/filament/Filament.html or whatever wacky artsy direction you like.

Best courses for learning graphics programming?
Use https://github.com/jkuhlmann/cgltf to parse the files. https://github.com/ocornut/imgui for your UI. Maybe https://www.libsdl.org/ just to set up a window, handle mouse clicks and initialize the GL context in that window.

I was learning OpenGL and, I needed a suggestion : Which are the best 3D model formats (In terms of ease of loading)
Use glTF and https://github.com/jkuhlmann/cgltf Or, looks like you are using C#, so https://github.com/vpenades/SharpGLTF

What is the best FBX loader for modern OpenGL? (C++)
Do you really have to use fbx? An open format like gltf is better supported, and there are bazillions loaders(I use cgltf without any issues, which is also used by raylib, Unigine and bgfx). It's also a perfect fit for OpenGL.

PortableGL: An implementation of OpenGL 3.x-ish in clean C
I recently discovered this pattern in cgltf (https://github.com/jkuhlmann/cgltf), and I agree, it makes deployment so much nicer.
-
Good entry-level model format with animation
Use https://github.com/jkuhlmann/cgltf It’s the most popular loader.
- Any opensource lib for loading gitf files? Something lightweight if possible
-
Is it worth writing a software raytracer before going into hardware accelerated RTX?
It's easy to generate a BVH for a generated triangle set (like a fractal pyramid or a dense cube). But, quickly generating a high quality BVH for a loaded model requires some research. Use https://github.com/jkuhlmann/cgltf to load models.

How to become a tools/graphics/engine programmer
Write a simple glTF viewer in OpenGL. This is a throw-away warm-up. So, don't fret over the code. Don't do anything complicated. Shoot for a simple, forward renderer for a simple, animated character with trivial Phong lighting, diffuse map, normal map and a basic directional shadow map. Use OpenGL ES 3.0/GL 4.3 API with no crazy features. Don't worry about performance. Use https://github.com/jkuhlmann/cgltf to load the files. KTX is a great container for textures.

Will the same texture used in many gltfs be duplicated in memory?
and https://gltf-transform.donmccurdy.com/
-
Memory limit for meshes
Is there any optimization being done on the model (KTX compression for the textures, DRACO compression on the mesh data, etc)? 210 MB is indeed a lot and I'm not sure there's any good way to be able to use that while keeping the scene renderable. You might want to look into glTF-Transform if you haven't already.

Decreasing .glb file size
You can give https://github.com/donmccurdy/glTF-Transform a go.
